Answers
How did we go about computing the above missing figures from the given table?
1) In the first line item - the Sales Price, Percent Saved and Percent Paid are given.
To work out the Original Price, we can state that: if 20% off the value of x = 800 what is x, (where x is the Original Price)?
If 20% is taken off the value of x, we need to find the original value of x before the discount was applied. We can set up the following equation:
x - 20% of x = 800
Simplifying by factoring out x on the left side, we get:
x * (1 - 20%) = 800
Converting 20% to a decimal, we get:
x * (1 - 0.20) = 800
Simplifying, we get:
x * 0.80 = 800
Dividing both sides by 0.80, we get:
x = 1000
Therefore, the original value of x before the 20% discount was applied is $1000.
Since the Original price is $1000, and the Sales price is $800, that means the Amount of Discount ($) is:
Original Price - Sales Price
= $1,000 - $800
= $200
Thus, the discount value for the Television is $200and the original price is $1000.
2) With regard to the sneakers, Original Price was $80 and the percent saved is 25%.The percentage saved is 75%.
Thus, the Sales Price = Original Price - (Original Price * Percent Saved)
Sales Price = 80 - (80 * 25%)
Sales Price = 80 - 20
Sales Price = $60
Since $20 was removed form the Original Price, that means the Amount of Discount ($) is $20.
3)
For the Video Game, we know the Sales Price and the Percent Paid, which is 90%.
That means $54 = 90% of x, where x is the Original Price.
To find x,
54 = 0.9x
x = 54/0.9
x (Original Price) = $60
Thus, the Original Price of the Video Game is $60.
Since Original Price = $60; and
Sales Price = $54
Amount discounted = Original Price - Sales Price
Amount discounted = 60-54
Amount discounted = $6
As a percentage of the Original Price $6 is: 6/60 * 100
= 10%
4) For the MP3 player, we know that that the Sales Price = $51.60 which is 60% (Percent Paid) of the Original Price. We also know that the Percent saved is 40% of the Original price.
Thus, if $51.6 is 60% of the original price, we can use the following proportion to find the original price:
60% = $51.6 / original price
To solve for the original price, we can isolate it by multiplying both sides by the reciprocal of 60%, which is 100% / 60%, or 5 / 3:
original price = $51.6 / (60%)
original price = $51.6 / (0.60)
original price = $86
Therefore, the original price before the 60% reduction was $86.
Amount of Discount = Original Price - Sales Price
= 86 - 51.6
= $34.4
Thus, Original Price and Amount of Discount for the MP3 Player are $86.00 and $34.40 respectively.
5)
For the book, we know that the Amount of Discount is $2.60 which is 80% (Percent Paid) of the Original Price.
If $2.6 is 20% of the original price, we can use the following proportion to find the original price:
20% = $2.6 / original price
To solve for the original price, we can isolate it by multiplying both sides by the reciprocal of 20%, which is 100% / 20%, or 5:
original price = $2.6 / (20%)
original price = $2.6 / (0.20)
original price = $13
Therefore, the original price before the 20% reduction was $13.
Since Original price = $13 and Discount given is $2.60, Thus,
Sales Price = Original Price - Discount Given
Sales Price = 13- 2.60
Sales Price = $ 10.40
Note that the percentage saved (discount) =
2.6/13 * 100
= 20%
Thus, the Percentage Saved = 20%.
6)
For the Snack Bar, we know that the Sales Price is $1.70 and the Amount of Discount is $0.30. This means that the Original Price =
Sales Price + Discount Given = 1.7 + 0.3
Original Price = $2.00
To find what percent 0.3 is of 2, we can use the following proportion:
x/100 = 0.3/2
where x is the percent we want to find.
To solve for x, we can cross-multiply and simplify:
2x = 30
x = 15
Therefore, $0.3 is 15% of $2 which is the percent saved.
If the percent saved is 15%, then the percent paid is:
100 - 15
= 85%
Thus, the percent paid is 85% of the Original Price.

As a result, the arithmetic progression's first term is 22 and its first fifteen terms add up to 735. The AP's initial term is 22 and its first fifteen terms add up to 735.
The total of the first seven terms is seventy-five.
The formulae for the nth term and the sum of an arithmetic progression can be used to solve the issue.
We have the following using the nth term formula:
a + 5d = 37\s(6/2)(2a + 5d) = 147
3a + 15d = 147\sa + 5d = 49

(a + 1/a)³ = a³ + 3a + 3/a + 1/a³
We are given that a + 1/a = 4, so we can substitute that into the identity and simplify:
(a + 1/a)³ = (4)³ = 64
a³ + 3a + 3/a + 1/a³ = 64
a³ + 1/a³ + 3(a + 1/a) = 64
a³ + 1/a³ + 3(4) = 64
a³ + 1/a³ = 52
Therefore, we have proved that a³ + 1/a³ = 52 when a + 1/a = 4.
2100 dollars is placed in an account with an annual interest rate of 5%. To the nearest year, how long will it take for the account value to reach 5100 dollars?
Answers
Therefore, it will take about 11 years for the account value to reach 5100 dollars.
What is percent?Percent is a way of expressing a quantity as a fraction of 100. The symbol "%" is used to represent percent. For example, if we say that an interest rate is 5%, it means that the interest is 5/100 or 0.05 as a decimal. Percentages are commonly used in finance, economics, and everyday life to express rates, proportions, and changes in quantities.
Here,
We can use the formula for compound interest to solve this problem:
A = P(1 + r/n)ⁿˣ
where A is the amount of money in the account after x years, P is the principal amount (initial deposit), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and x is the time (in years).
We are given that P = 2100, r = 0.05, and we want to find the value of x when A = 5100. Let's assume that the interest is compounded annually (n = 1). Substituting the given values into the formula, we get:
5100 = 2100(1 + 0.05)ˣ
Dividing both sides by 2100, we get:
(1 + 0.05)ˣ = 5100/2100
Simplifying the right-hand side, we get:
(1 + 0.05)ˣ = 2.42857
Taking the natural logarithm of both sides, we get:
ln(1 + 0.05)ˣ = ln 2.42857
Using the power rule of logarithms, we can simplify the left-hand side:
x ln(1 + 0.05) = ln 2.42857
Dividing both sides by ln(1 + 0.05), we get:
x= ln 2.42857 / ln(1 + 0.05)
Using a calculator, we get:
x≈ 11.4
Rounding this to the nearest year, we get:
x ≈ 11 years

Similarly, a random sample of 20 Walmart stores (group 2) had an average basket price of $67.635 with a standard deviation of $12.936. Perform a two independent samples t-test on the hypotheses Null Hypothesis: μ1 = μ2, Alternative Hypothesis: μ1 ≠ μ2. What is the test statistic and p-value of this test? You can assume that the standard deviations of the two populations are statistically similar.

4) Test Statistic: -2.052, P-Value: 0.977
5) Test Statistic: 2.052, P-Value: 0.0461
Answers
From the given data, the test statistic is -2.052 and the p-value is 0.0461. The correct answer is option 5.
To perform a two independent samples t-test, we can use the following formula to calculate the test statistic:
t = (x₁ - x₂) / (s_p × √(1/n₁ + 1/n₂))
where x₁ and x₂ are the sample means, n₁ and n₂ are the sample sizes, s_p is the pooled standard deviation, calculated as:
s_p = √(((n₁ - 1) × s₁² + (n₂ - 1) × s₂²) / (n₁ + n₁ - 2))
Let's calculate the test statistic:
x₁ = 60.345, s₁ = 10.8968, n₁ = 25
x₂ = 67.635, s₂ = 12.936, n₂ = 20
s_p = √(((25 - 1) × 10.8968² + (20 - 1) × 12.936²) / (25 + 20 - 2)) = 11.8074
t = (60.345 - 67.635) / (11.8074 × √(1/25 + 1/20)) = -2.052
The degrees of freedom for the t-distribution can be calculated as:
df = n₁ + n₂ - 2 = 43
Using a two-tailed t-test at a significance level of 0.05, the critical t-value is ±2.016.
The p-value for the test is the probability of obtaining a t-value as extreme or more extreme than the calculated t-value, assuming the null hypothesis is true. Since the calculated t-value is outside the critical region (|t| > 2.016), the p-value is less than 0.05 and we can reject the null hypothesis in favor of the alternative hypothesis.

Si O es el centro de la circunferencia de la figura y el ∡ ABC = 40°, halla la medida del ∡X
Answers
As in the given circle, the measure of the value of ∠X is 115°.
Now, let's look at point X. This point is on the same line as point B and is also on the circle. Since the angle subtended by an arc at the center of a circle is twice the angle subtended by the same arc at any point on the circle, we can find the measure of ∠AXB by first finding the measure of arc ACB. Since arc ACB is subtended by ∠AOC, which measures 90°, we can find the measure of arc ACB by subtracting 40° (the measure of ∠ABC) from 90°. Therefore, arc ACB measures 50°. This means that ∠AXB is half the measure of arc ACB, so ∠AXB measures 25°.
Therefore, the measure of ∠X is 180° minus the sum of ∠AXB and ∠ABC, which gives us:
∠X = 180° - (25° + 40°) = 115°.

Answers
The probability that among 10 such cars tested, 3 will average less than 28 miles per gallon, 6 will average from 28 to 32 miles per gallon, and 1 will average more than 32 miles per gallon is given by 0.0020125
Let X be the number of cars among ten that averages less than 28 miles per gallon. Let Y be the number of cars among ten that average from 28 to 32 miles per gallon. Let Z be the number of cars among ten that average more than 32 miles per gallon. We are to find P(X = 3, Y = 6, Z = 1).
Firstly, let us find the probability of getting 3 cars among 10 cars that will average less than 28 miles per gallon.
The probability of getting exactly 3 cars among 10 cars that will average less than 28 miles per gallon is given by the probability mass function:
P(X = 3) = (10C3) (0.4)³ (0.6)⁷
= (10 x 9 x 8 / 3 x 2 x 1) (0.064) (0.096)
= 0.23 (approximately)
Similarly, the probability of getting 6 cars among 10 cars that will average from 28 to 32 miles per gallon is given by the probability mass function:
P(Y = 6) = (10C6) (0.5)⁶ (0.5)⁴
= (10 x 9 x 8 x 7 x 6 x 5 / 6 x 5 x 4 x 3 x 2 x 1) (0.156) (0.063)
= 0.25 (approximately)
Finally, the probability of getting 1 car among 10 cars that will average more than 32 miles per gallon is given by the probability mass function:
P(Z = 1) = (10C1) (0.1)¹ (0.9)⁹
= (10) (0.1) (0.348)
= 0.035
Therefore, the answer is:
P(X = 3, Y = 6, Z = 1) = P(X = 3) P(Y = 6) P(Z = 1)
= 0.23 x 0.25 x 0.035
= 0.0020125 (approximately)

Complete the problem. Let f(x)=(1)/(x) and g(x)=(1)/(x+3). Describe the transformation from f(x) to g(x).
Answers
The transformation from f(x) to g(x) involves a horizontal shift and a change in the slope of the graph.The function g(x) is obtained from the function f(x) by a vertical shift of 3 units to the left.
Specifically, the denominator of g(x), x+3, represents a horizontal shift of 3 units to the left compared to the denominator of f(x), x. As a result, g(x) is shifted to the left relative to f(x). Furthermore, the shift causes the graph of g(x) to be steeper than that of f(x) at x=0. This is because, for small values of x, the difference between (1)/(x) and (1)/(x+3) becomes larger as x gets smaller. Therefore, the transformation from f(x) to g(x) involves a horizontal shift and a change in the slope of the graph.

what is the radius if a circle with diameter 3cm
Which diagram shows how to set a pair of compasses to draw a circle with diameter 3cm
Answers
Answer: The radius of a circle is half of its diameter. Therefore, if the diameter of the circle is 3 cm, then the radius is 1.5 cm.
To set a pair of compasses to draw a circle with diameter 3 cm, open the compasses to a distance of 1.5 cm (which is the radius of the circle). The correct diagram in the link provided shows the compasses set to the correct radius.
So its A
The radius of the circle is 1.5cm.
A circle's diameter is divided in half by its radius. Thus, if the circle's diameter is 3 cm, the radius is:
radius = diameter/2 = 3cm/2 = 1.5cm
what is the radius?Any circular object's radius is the measurement from the centre to its outermost border or boundary. A radius is a dimension that applies to spheres, semispheres, cones with circular bases, and cylinders with circular bases in addition to circles.
It is possible to define a circle as the locus of a point travelling on a plane while maintaining a constant distance from a fixed point. The radius of a circle is the distance from any point on the circle to its centre. The fixed point is referred to as the centre of the circle.
The distance along a line drawn between two points on a circle and through the centre of the circle is the diameter of the circle. It is equivalent to double the circle's radius. It is typically indicated with a d or a D.
Diameter = 2 x Radius
Or
Radius = diameter / 2.
The circle's longest chord equals its diameter.
Moreover, we may relate a circle's area and circumference to its diameter.
Circle circumference equals (Diameter)
Circle area equals /4 (Diameter[tex])^2.[/tex]

In an integer programming problem, if it is desired to have variable X be exactly twice the value of variable Y, the constraint that enforces this condition would be written as: A. 2X + Y = 0 B. X + 2Y = 0 C. 2X - Y = 0 D. X - 2Y = 0
Answers
The constraint 2X - Y = 0 states that the difference between variable X and twice variable Y must be equal to 0, meaning that X must be exactly twice the value of Y.The correct answer is C. 2X - Y = 0.
This constraint states that the difference between variable X and twice variable Y must be equal to 0. In other words, the value of variable X must be exactly twice the value of variable Y. This can be mathematically represented as 2X - Y = 0, meaning that 2 multiplied by X minus Y must equal 0. To illustrate this, let us assume that the value of variable X is 10 and the value of variable Y is 5. This means that 2X is equal to 20 and Y is equal to 5. When we subtract Y from 2X, we get 20 - 5 = 15. However, since the constraint states that the difference between X and twice Y must equal 0, the value 15 does not satisfy the condition. Therefore, the values of X and Y must be adjusted until the difference between X and twice Y equals 0. To satisfy the constraint, the value of X must be equal to 20 and the value of Y must be equal to 10. This means that X is exactly twice the value of Y, which satisfies the condition set by the constraint 2X - Y = 0.

Place the two small triangles on top of the square what is the area of the each small triangle
Answers
The area of each small triangle is equal to √(7)/8 times the square of the length of one side of the square.
First, we need to find the area of the larger triangle that is created by placing the two small triangles on top of the square. Let's call the base of the larger triangle "b" and the height of the larger triangle "h".
To find "b", we can use the length of one side of the square since the two small triangles are placed on top of the square. Let's call the length of one side of the square "s".
Since the two small triangles are congruent, we know that the base of each small triangle is equal to half of one side of the square, which is s/2. Therefore, the total base of the larger triangle is equal to the sum of the bases of the two small triangles, which is s/2 + s/2 = s.
To find "h", we need to use the Pythagorean theorem since the larger triangle is a right triangle. Let's call the hypotenuse of the larger triangle "c". Since the hypotenuse is the diagonal of the square, we know that its length is √(2)*s.
Using the Pythagorean theorem, we can find the height of the larger triangle:
h² + (s/2)² = c² h² + (s/2)² = (√(2)s)² h² + s²/4 = 2s² h² = 7s²/4 h = √(7)/2 x s
Now that we have found "b" and "h", we can use the formula for the area of a triangle:
Area = 1/2 x base x height
Area of the larger triangle = 1/2 x s x √(7)/2 x s = √(7)/4 x s²
Finally, we can find the area of each small triangle by dividing the area of the larger triangle by two:
Area of each small triangle = 1/2 x (√(7)/4 x s²) = √(7)/8 x s²

Jobs arriving to a computer server have been found to require CPU
time that can be modeled by an exponential distribution with a mean of 140 ms
(milliseconds). The CPU scheduling discipline is quantum-oriented so that a job not
completed within a quantum of 100ms will be routed back to the tail of the queue of waiting
jobs.
a. What is the probability that an arriving job is forced to wait for a second quantum (that is,
it will be forced to wait for more than 100ms)?
b. What is the probability that the fifth arriving job of a day will be the first one that is
forced to wait for a second quantum (that is, it will be forced to wait for more than
100ms)
Answers
The probability of the fifth job being the first one that is forced to wait for a second quantum is 0.0266.
What is probability?Probability is the measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. Probability is calculated by taking all possible outcomes into consideration and then dividing the number of favourable outcomes by the total number of possible outcomes.
The probability that an arriving job is forced to wait for a second quantum is the probability of that job requiring more than 100ms of CPU time. This probability can be calculated by taking the cumulative distribution function of the exponential distribution and subtracting the probability of the job requiring 100ms or less of CPU time. The probability of the job requiring more than 100ms of CPU time is 0.6853.
This probability can be calculated by taking the probability of the first four jobs requiring less than 100ms of CPU time and multiplying it by the probability of the fifth job requiring more than 100ms of CPU time.

find the length of the missing side of the right triangle ABC. Leave your answer in simplest radical form
Answers
Very complicated sorry if i’m wrong
Answer:
Step-by-step explanation
ayo so basically this is a pythagorus theorum question
the formula is
c²= a² + b²
where c is the hypotenuse (the longest line , opposite of the right angle aka here 13ft !!)
a and b , where a is the down line as a (4ft ) and b the unknown one
(just remember and lookout for the hypotenuse!)
so now put the numbers in formula
(13)²= (4)² +(b)²
169= 16 +(b)²
169-16=(b)²
153= (b)²
(put b first )
(b)² = 153
√(b)²= √153
(the square gets cut with the square root)
b= 12.36931688

The property tax in one town was $6. 95 per $1000 value in the year 2012. The tax increased to $7. 71 per $1,000 value in 2013. What effect did that have on the property tax for a house with a value of $100,000?
a) increase $76
b) decrease $96
c) increase $ 791
d) decrease $695
Answers
The effect of the tax increase from 2012 to 2013 for a house with a value of 100,000 was an increase of 76.
The property tax in one town was 6.95 per 1000 value in the year 2012. In 2013, the property tax increased to 7.71 per 1000 value. This means that in 2013, the property tax for a house with a value of 100,000 would be 771.
To calculate the effect that the tax increase had on the property tax for a house with a value of 100,000, we can use the following formula:
Effect of Tax Increase = (New Tax Rate - Old Tax Rate) x Value of Property
Using this formula, the effect of the tax increase for a house with a value of $100,000 would be:
Effect of Tax Increase = ($7.71 - $6.95) x $100,000
Effect of Tax Increase = $0.76 x $100,000
Effect of Tax Increase = $76
