If x is the average of m and 9, y is the average of 2m and 15, and z is the average of 3m and 18, what is the average of x, y, and z in terms of m

If X Is The Average Of M And 9, Y Is The Average Of 2m And 15, And Z Is The Average Of 3m And 18, What

Answers

Answer 1

Answer: To find the average of x, y, and z in terms of m, we first need to find expressions for x, y, and z in terms of m:

x = (m + 9)/2

y = (2m + 15)/2

z = (3m + 18)/3 = (m + 6)

To find the average of x, y, and z, we add them up and divide by the number of terms:

average = (x + y + z)/3

Substituting the expressions for x, y, and z, we get:

average = [(m + 9)/2 + (2m + 15)/2 + (m + 6)]/3

Simplifying the expression by combining like terms, we get:

average = (4m + 30)/6

Simplifying further by dividing both the numerator and denominator by 2, we get:

average = (2m + 15)/3

Therefore, the average of x, y, and z in terms of m is (2m + 15)/3.

A towns population has been decreasing at a constant rate. In 2010 the population was 7,900. By 2012 the population had dropped to 7,700. assume this trend continues. Identify the year in which the population will reach 0. Show work.

Answers

Answer:

Step-by-step explanation:

To identify the year in which the population will reach 0, we need to determine the rate at which the population is decreasing, and use that rate to predict when the population will be 0.

We can use the two data points given to find the rate of population decrease. Let P be the population and t be the time in years since 2010. Then we have:

P(0) = 7900 (population in 2010)

P(2) = 7700 (population in 2012)

We can find the rate of population decrease by using the formula for the slope of a line:

slope = (P(2) - P(0)) / (t(2) - t(0)) = (7700 - 7900) / (2 - 0) = -100/year

The negative sign indicates that the population is decreasing, and the magnitude of the slope (-100/year) tells us the rate at which it is decreasing.

To find the year in which the population will reach 0, we can use the point-slope form of a line:

P - P(0) = slope * (t - t(0))

where P is the population, t is the time in years since 2010, P(0) is the population in 2010, and t(0) is 0 (the year 2010).

Substituting the known values, we get:

P - 7900 = -100 * (t - 0)

Simplifying, we get:

P = -100t + 7900

To find the year in which the population will reach 0, we set P = 0 and solve for t:

0 = -100t + 7900

100t = 7900

t = 79

Therefore, the population will reach 0 in the year 2010 + 79 = 2089.

The solution is, the population will reach 0 in the year 2089.

What is  simplification?

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Substituting the known values, we get:

P - 7900 = -100 * (t - 0)

Simplifying, we get:

P = -100t + 7900

To find the year in which the population will reach 0, we set P = 0 and solve for t:

0 = -100t + 7900

100t = 7900

t = 79

Therefore, the population will reach 0 in the year 2010 + 79 = 2089.

Determine the equation of the circle graphed below.

Answers

Answer:

(x - 3)² + (y + 4)² = 29

Step-by-step explanation:

the equation of a circle in standard form is

(x - h )² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

we are given the centre  and require to find the radius r

the distance from the centre to a point on the circle gives r

using the distance formula to find r

r = [tex]\sqrt{(x_{2}-x_{1 )^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (3, - 4 ) and (x₂, y₂ ) = (8, - 2 )

r = [tex]\sqrt{(8-3)^2+(-2-(-4))^2}[/tex]

  = [tex]\sqrt{5^2+(-2+4)^2}[/tex]

  = [tex]\sqrt{25+2^2}[/tex]

  = [tex]\sqrt{25+4}[/tex]

  = [tex]\sqrt{29}[/tex]

then equation of circle with centre (3, - 4 ) and r = [tex]\sqrt{29}[/tex] is

(x - 3)² + (y - (- 4) )² = ([tex]\sqrt{29}[/tex] )² , that is

(x - 3)² + (y + 4)² = 29

Answer:

[tex](x-3)^2+(y+4)^2=29[/tex]

Step-by-step explanation:

To find:-

The equation of the graphed circle.

Answer:-

We can see that the centre of the given graphed circle is (3,-4) and one of the point on the circumference of the circle is (8,-2) .

Now we can calculate the radius of the circle using these two points as radius is the distance between centre and any point on the circle.

Distance formula:-

[tex]\longrightarrow \boxed{ d =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2}} \\[/tex]

On substituting the respective values, we have;

[tex]\longrightarrow d = \sqrt{ (8-3)^2+\{ -4-(-2)\}^2}\\[/tex]

[tex]\longrightarrow d =\sqrt{ 5^2 + (-4 +2)^2}\\[/tex]

[tex]\longrightarrow d =\sqrt{ 5^2+2^2} \\[/tex]

[tex]\longrightarrow d =\sqrt{25+4} \\[/tex]

[tex]\longrightarrow d =\sqrt{ 29}\rm{units}\\[/tex]

Now we can use the standard equation of circle to find out the equation of the circle as ,

Standard equation of circle:-

[tex]\longrightarrow \boxed{ (x-h)^2+(y-k)^2=r^2} \\[/tex]

where ,

(h,k) is the centre.r is the radius.

On substituting the respective values, we have;

[tex]\longrightarrow (x-3)^2+\{ y-(-4)\}^2 = (\sqrt{29})^2 \\[/tex]

[tex]\longrightarrow \underline{\underline{\red{(x-3)^3+(y+4)^2=29}}}\\[/tex]

This is the required equation of the circle.

You answered 7 out of 11 correctly. Asking up to 12.

Answers

The sales of bottled water and carbonated soft drinks will be the same in the year 2028 (in 5.323 years).

How to find the amount sold will be same

To find the year when the sales of soda and water will be equal, we need to solve the equation:

Soda = Water

12.5 - 0.2475t = 8.2 + 0.56t

where

t = time

collecting like terms

12.5 - 8.2 = 0.2475t + 0.56t

4.3 = 0.8075t

Then we can solve for t by dividing both sides by 0.8075:

t ≈ 5.323

If t is in years, this tells us that the sales of soda and water will be equal in approximately 5.323 years.

To find the year when this will happen, we need to add 5.323 to the current year.

Assuming the current year is 2023, we get:

2023 + 5.323 ≈ 2028.323

The AP Chemistry class is mixing 100 pints of liquid together for an experiment. Liquid A contains 10% acid, liquid B contains 40% acid, and liquid C contains 60% acid. If there are twice as many pints of liquid A than liquid B, and the total mixture contains 45% acid, find the number of pints needed for each liquid.

Answers

Therefore, they need 25 pints of liquid A, 12.5 pints of liquid B, and 62.5 pints of liquid C to make the final mixture.

What is equation?

An equation is a mathematical statement that shows that two expressions are equal. It contains one or more variables, and the goal is to solve for the value(s) of the variable(s) that make the equation true.

Given by the question.

Let's denote the number of pints of liquid A, B, and C as A, B, and C, respectively. We know that:

A + B + C = 100 (since they are mixing 100 pints in total)

We also know that the concentration of acid in the final mixture is 45%, so:

0.1A + 0.4B + 0.6C = 0.45(100) = 45

Finally, we are told that there are twice as many pints of liquid A as liquid B, so:

A = 2B

We can use these three equations to solve for A, B, and C. First, substitute A = 2B into the equation A + B + C = 100:

2B + B + C = 100

3B + C = 100

Next, substitute A = 2B into the equation 0.1A + 0.4B + 0.6C = 45:

0.1(2B) + 0.4B + 0.6C = 45

0.2B + 0.4B + 0.6C = 45

0.6B + 0.6C = 45

Simplify this equation by dividing both sides by 0.6:

B + C = 75

We now have two equations with two variables:

3B + C = 100

B + C = 75

Subtracting the second equation from the first, we get:

2B = 25

B = 12.5

Substituting this value back into B + C = 75, we get:

12.5 + C = 75

C = 62.5

Finally, using A = 2B, we get:

A = 25

The normal distribution is  X ~ N(17, 0.8), the median is equal to mean which is 17 feet, the z-score is 2.5, the probability that a randomly selected giraffe will be shorter than 18 feet tall is 0.8944.

What is the distribution of X

a. The distribution of X is normal, which we can write as X ~ N(17, 0.8).

b. Since the normal distribution is symmetric, the median is equal to the mean, which is 17 feet.

c. To find the z-score for a giraffe that is 19 feet tall, we use the formula:

z = (x - μ) / δ

where x is the height of the giraffe, mu is the mean height of the population (17 feet), and sigma is the standard deviation (0.8 feet). Plugging in the values, we get:

z = (19 - 17) / 0.8 = 2.5

So the z-score for a giraffe that is 19 feet tall is 2.5.

d. To find the probability that a randomly selected giraffe will be shorter than 18 feet tall, we need to find the area under the normal distribution curve to the left of x = 18. We can use a standard normal distribution table or a calculator to find this area, or we can standardize the value of x and use the standard normal distribution table or calculator. Using the latter method, we have:

z = (x - μ) / δ = (18 - 17) / 0.8 = 1.25

Looking up the area to the left of z = 1.25 in a standard normal distribution table or using a calculator, we find that the probability is approximately 0.8944. So the probability that a randomly selected giraffe will be shorter than 18 feet tall is 0.8944.

e. To find the probability that a randomly selected giraffe will be between 16.7 feet and 17.5 feet tall, we need to find the area under the normal distribution curve between x = 16.7 and x = 17.5. Again, we can standardize the values of x and use a standard normal distribution table or calculator. We have:

z1 = (16.7 - 17) / 0.8 = -0.38

z2 = (17.5 - 17) / 0.8 = 0.63

Looking up the area between z1 = -0.38 and z2 = 0.63 in a standard normal distribution table or using a calculator, we find that the probability is approximately 0.2981. So the probability that a randomly selected giraffe will be between 16.7 feet and 17.5 feet tall is 0.2981.

f. The 90th percentile for the height of the giraffe is the height x such that 90% of the giraffes have a height below x. In other words, we need to find the value of x such that the area under the normal distribution curve to the left of x is 0.9. Using a standard normal distribution table or calculator, we can find the z-score corresponding to the 90th percentile, which is approximately 1.28. We can then use the formula for z-score to find the corresponding height x:

z = (x - μ) / δ

1.28 = (x - 17) / 0.8

Solving for x, we get:

A nurse’s aide has earned $21,670. She earned $1,970 this month. How much is deducted this
month for Social Security? For Medicare?

Answers

Answer:

The Social Security tax rate is 6.2% and the Medicare tax rate is 1.45%. To calculate the amount deducted from the nurse's aide's earnings this month for Social Security and Medicare:

Social Security:

Multiply the earnings for the month by the Social Security tax rate:

$1,970 x 0.062 = $121.94

Therefore, $121.94 is deducted from the nurse's aide's earnings this month for Social Security.

Medicare:

Multiply the earnings for the month by the Medicare tax rate:

$1,970 x 0.0145 = $28.54

Describe Sine?

In trigonometry, the sine function is one of the primary trigonometric functions that relates the ratio of the length of the side opposite an acute angle in a right triangle to the length of the hypotenuse. The sine function is defined as:

sine (θ) = opposite / hypotenuse

where θ is the measure of the acute angle in radians or degrees.

The sine function is a periodic function, meaning it repeats itself after every 2π radians or 360 degrees. The graph of the sine function is a wave that oscillates between -1 and 1, with the midline at y = 0. The amplitude of the wave is 1, which represents the maximum height of the wave above and below the midline.

The sine function is used in many real-world applications, such as in engineering, physics, and astronomy to model waves, oscillations, and periodic phenomena. It is also used in geometry to calculate the sides and angles of triangles, as well as in calculus to solve differential equations and to describe the motion and behavior of complex systems.

Using a calculator, we get sin88° ≈ 0.99. Rounding to the nearest hundredth, sin88° ≈ 0.99.

What are a definition and an example of a linear equation?

Equations with variables of power 1 are referred to as linear equations. One example with only one variable is where ax+b = 0, where a and b are real values and x is the variable.

                                 An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

1/4x + 2 = -5/8x - 5

Add 5 to both sides.

In Vincent garden 1/6 of the flowers are daisies, and 1/8 of the flowers are snapdragons.

Answers

In Vincent's garden, about 34/48 of the flowers are neither daisies nor snapdragons.

We need to find the fraction of flowers in Vincent's garden that are neither daisies nor snapdragons. To do this, we need to subtract the fractions of daisies and snapdragons from 1.

The fraction of flowers that are daisies is 1/6, and the fraction that are snapdragons is 1/8. To find the common denominator, we can multiply 6 and 8 to get 48.

So, the fraction of flowers that are neither daisies nor snapdragons is:

1 - 1/6 - 1/8

= 48/48 - 8/48 - 6/48

= (48 - 8 - 6)/48

= 34/48

Therefore, 34/48 of the flowers in Vincent's garden are neither daisies nor snapdragons.

The Pearson correlation coefficient r for the given points is: 0.191.

How to find the r Pearson correlation coefficient r?

We can use the formula for Pearson correlation coefficient r:

r = [nΣ(xy) - ΣxΣy] / sqrt([nΣ(x²) - (Σx)²][nΣ(y²) - (Σy)²])

where n is the number of data points, Σ represents the sum, x and y are the variables, and xy, x², and y² represent the products and squares of the variables.

We can first calculate the sums and products:

n = 7

Σx = 28

Σy = 36

Σ(x²) = 140

Σ(y²) = 248

Σ(xy) = 152

Using these values, we can plug them into the formula for r:

r = [nΣ(xy) - ΣxΣy] / sqrt([nΣ(x²) - (Σx)² ][nΣ(y²) - (Σy)²])

= [7(152) - (28)(36)] / sqrt([7(140) - (28)^2][7(248) - (36)²])

=  56 / 293

= 0.191

Martina's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Martina $4.30 per pound, and type B coffee costs $5.55 per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of $689.00. How many pounds of type A coffee were used?

Answers

Hence, in response to the provided question, we can say that Martina equation used 26 pounds of type A coffee in the mix as a result.

What is equation?

An algebraic equation is a method of connecting two quotes by using the equals symbol (=) to express equality. In algebra, an explanation is a definitive expression that verifies the equivalency of two formula. For example, the identical character divides the numbers 3x + 5 and 14. A linear equation might be used to recognize the connection that existing between the texts written on separate sides of a letter. The product and application both frequently the same. 2x - 4 equals 2, for example.

Assume Martina used x pounds of type A coffee in her blend. Then, based on the information provided, she used 4 pounds of type B coffee.

Type A coffee costs $4.30 per pound, so x pounds of type A coffee costs $4.30x dollars.

Because the entire cost of the blend is given as $689.00, we may formulate the following equation:

4.30x + 22.20x = 689.00

Mixing similar phrases yields:

26.50x = 689.00

When we divide both sides by 26.50, we get:

x = 26

4. Find each interior angle


Sort from smallest to largest

Answers

Answer:

50, 75, 90, 105, 110

Step-by-step explanation:

All angles of a pentagon add up to 540 degrees

So;

Finding all the inner angles first;

x = 180 - 50 = 130

y = 180 - 75 = 105

So, 130 + 105 + 90 + (2x + 10) + (2x + 5) = 540

or, 4x = 200

Therefore, x = 50

2x + 5 = 105

2x + 10 = 110

Hence, the angles in ascending order are:

50, 75, 90, 105, 110
