The probability of rolling a one on the first die and a four on the second die is 1/36.

This is because there are six possible outcomes for each die (1, 2, 3, 4, 5, and 6) and the probability of rolling a specific number on one die is 1/6. To find the probability of rolling a specific number on two dice, you would multiply the individual probabilities of each die (1/6 x 1/6 = 1/36). Since there is only one combination of rolling a one on the first die and a four on the second die, the probability is 1/36.

The range of scores that Steve needs to get an average of 70 to 79 is 66 to 87 Points.

To find the range of scores that Steve needs to have to stay in the 70 to 79 range we first need to define the variables that we need to find.

Let x = Score that Steve needs

Since the exam is worth 3 exams, we will then use 3x to denote the weight of the final exam.

Now we need to add all the other exams and divide it by the number of exams.

[tex]\frac{3x + 70+77+71+71}{7} = 70[/tex]

3x + 292 = 7 *70

3x = 490 -292

3x = 198

[tex]\frac{3x}{3} =\frac{198}{3}[/tex]

x = 66

Now let's look for the score that Steve needs to get to a 79 average.

[tex]\frac{3x + 70+77+71+71}{7} = 79[/tex]

3x + 292 = 7 * 79

3x + 292 = 553

3x = 553 - 292

3x = 261

x = 87

So the range of scores is 66 to 87 Points.

The probability that the sum of all the top faces is divisible by 6 is 1/6.

1.This is because there are six possible outcomes when the dice are thrown, and only one of these outcomes (where the sum of the top faces is divisible by 6) has a probability of 1/6.

2.The other five outcomes have a probability of 0.
3.To explain this further, consider the following example: if we throw 10 dice, the possible outcomes are 6^10, or 6,561 outcomes. Of these 6,561 outcomes, only 1,089 will result in a sum of the top faces that is divisible by 6.

4.Therefore, the probability that the sum of all the top faces is divisible by 6 is 1,089/6,561, or 1/6.

There are 49 distinct ordered pairs of positive integers (x, y) such that the least common multiple of x & y is 1,000.

The least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, usually denoted by lcm, is the smallest positive integer that is divisible by both a and b.

Given that, how many distinct ordered pairs of positive integers (x, y) such that the least common multiple of x & y is 1,000,

1000 = 10³ = 2³×5³

y = [tex]2^c[/tex]×[tex]5^d[/tex]

where

0 ≤ a, b, c, d ≤ 3

a or c = 3

Case 2 : Exactly 3 of  a, b, c, d = 3

a = b = c = 3, d = 0, 1, 2

a = b = d = 3, c = 0, 1, 2

a = c = d = 3, b = 0, 1, 2

b = c = d = 3, a = 0, 1, 2

4(1×1×1×3) = 12

Case 3 : Exactly 4 of a, b, c, d = 3

The length of the side XY taken out by using trigonometric formulas is 12.208 cm.

Now we know that ΔWXY is a right-angled triangle. With ∠XWY = 90°

Hence we see that we can use the trigonometric formulas to find the length of XY

Since ∠YWX = 35° with XW being the corresponding side and XY being the hypotenuse we can use the formula

cosx = base/hypotenuse

Now using a scientific calculator we can calculate

cos35 to be 0.81915

or, base/hypotenuse = 0.81915

or, WX/XY = 0.81915

or, 10/XY = 0.81915

or, XY = 10/0.81915

or, XY = 12.208 cm

Hence the length of side XY is 12.208 cm.

The speed travelled by mars in miles per minutes is 900. As Given that the mars revolves around the sun at a rate of approximately 15 miles per second.

We know that , Speed = distance / time

Hence we have speed of the mars as  15 miles/sec.

To convert the rate from miles/sec to miles/ minute we have to multiply the given with minute i.e 60 sec.

                    miles x min    =   miles x 60 sec          

                     sec x min              sec x min

           since , 1 minute = 60 sec

 hence, new speed = 15 x 60 miles/ minute.

Therefore , the speed travelled by mars in miles per minutes is 900.

( a) In two minutes mars will travel 900 x 2 times with the same rate.

The graph that represents the system is option D.

The first inequality y ≥ 3x + 1 represents a line with a slope of 3 and a y-intercept of 1, and it is shaded above the line. This line is a solid line.

The second inequality x < -3 represents a vertical line with an x-intercept of -3, and it is shaded to the left of the line. This line is a dashed line.

The solution of the system is the intersection of the two regions, which is the area on the coordinate plane that is shaded above the solid line and to the left of the dashed line.

So the graph that represents the system is the one that shows a solid line with a slope of 3 and a y-intercept of 1, with shading above the line, and a dashed line with an x-intercept of -3, with shading to the left of the line. This is option D.

He open his chutes at t = (3 ± √(-31)) / 2 seconds.

To find the time at which the person opened their parachute, we need to find the point of intersection between the two equations, F(t) and P(t).

The first equation is F(t) = -t^2 + 2t + 305, represents the fall before the parachute is open.

The second equation is P(t) = -t + 295, represents the fall after the parachute is open.

We can find the point of intersection by setting the two equations equal to each other and solving for t.

-t^2 + 2t + 305 = -t + 295

-t^2 + 3t = -10

t^2 - 3t + 10 = 0

using quadratic formula

t = (3 ± √(3^2 - 4110)) / 2*1

t = (3 ± √(9 - 40)) / 2

The function represent the given graph is f(x)= 1·(1/2)ˣ. Therefore, option B is the correct answer.

Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

As, seen from the graph passes through (0,1) point.

Now, put x = 0, we get

y = 1 from equation B or D.

Now, as the value of x increases towards negative direction i.e. -5, -6, ....

Then, the value of y will be zero.  

So, the function represent the graph is f(x)= 1·(1/2)ˣ

To calculate the speed of the Pepsi bottle when it has 1.2 seconds left in its fall, we would need to know the acceleration due to gravity. Assuming a standard gravitational acceleration of 9.8 m/s^2, we can use the following equation to calculate the speed:

Speed = (2 * acceleration * distance)^(1/2)

For the given quadratic function, the coefficient b is equal to 12.

The quadratic function can represent a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function, the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

The question gives some points of the quadratic function, see below.

  x  f(x)

−10  24

−9  17

−8  12

−7  9

−6  8

−5  9

−4  12

From the given data you can find the coefficients by solving the system linear equation.

You can write a system linear equation using the points: (-10,24) ,(-9,17) and (-8,12) for example. Then, you have three equations:

100a-10b+c=24 (1)

81a-9b+c=17    (2)

64a-8b+c=12   (3)

Isolate the coefficient a, you have [tex]a=\frac{24+10b-c}{100}[/tex]. Replacing the variable a in equations 2 and 3, you have:

[tex]81* \frac{24+10b-c}{100}-9b+c=17 (2) \\\\ 64* \frac{24+10b-c}{100}-8b+c=12 (3)[/tex]

Simplifying, you can rewrite it as:

[tex]\frac{-90b+19c+1944}{100}=17 (2) \\ \frac{-40b+9c+384}{25}=12 (3)[/tex]

Next step, you should isolate the coefficient b from the previous equation 2. You have:

[tex]\frac{-90b+19c+1944}{100}=17\\ \\ -90b=1700-19c-1944\\ \\ -90b=-244-19c\\ \\ b=-\frac{-244-19c}{90} = \frac{244+19c}{90}[/tex]

[tex]b=\frac{(244+19c)}{90} (4)[/tex]

Replacing the variable b in the previous equation 3, you have:

[tex]\frac{-40*\frac{244+19c}{90}+9c+384 }{25} =12\\[/tex]. Multiplying both sides by 25, you find the coefficient c:

[tex]\frac{25*(-40(\frac{244+19c}{90})+9c+384)}{25}=12*25\\ \\ -40(\frac{244+19c}{90})+9c+384=300\\ \\ -4(\frac{244+19c}{9})+9c+384=300\\ \\ (\frac{-976-76c}{9})+9c+384=300\\ \\ -976-76c+81c+3456=2700\\ \\ -76c+81c=2700+976-3456\\ \\ 5c=220\\ \\ c=44[/tex]

From the previous equation 4, you finally find the coefficient b. See below.

[tex]b=\frac{244+19c}{90} \\ b=\frac{244+19*44}{90}\\ \\ b=\frac{244+836}{90}\\ \\ b=\frac{1080}{90}\\ \\ b=12[/tex]

We'll use the pythagorean theorem converse.

Consider a triangle with sides a,b,c where c is the longest side.

There are 3 scenarios possible:

The middle or second scenario is probably what you're most familiar with. That's the famous pythagorean theorem without the term "converse" attached to it.

--------------

The two given sides are 8 inches and 10 inches.

Let's say the third side was 5 inches (choice F)

This means we have a triangle with sides a = 5, b = 8, c = 10

Then compute the following:

Since 89 < 100, we see that a^2+b^2 < c^2 is the case. Therefore the triangle with sides 5,8,10 is obtuse.

This will allow us to rule out choice F since we're looking for an acute triangle.

--------------

Now onto choice G.

This time the sides are: a = 6, b = 8, c = 10

Both results (a^2+b^2 and c^2) are the same at 100; so we see that a^2+b^2 = c^2.

Therefore we have a right triangle. We can rule out choice G.

--------------

Now onto choice H.

The triangle now has sides: a = 8, b = 10, c = 12

Since 164 > 144, we see that a^2+b^2 > c^2 is the case. Therefore the triangle with side lengths 8,10,12 is acute.

--------------

For the sake of completeness, let's go over choice J.

We find 164 < 169 which leads to the scenario a^2+b^2 < c^2. The triangle for choice J is obtuse. We can rule out choice J.

You can use something like GeoGebra to help visually verify these results.

While,

Target sale

1/2 × 100 = 50% off

Answer:

Target (option b/second option)

Step-by-step explanation:

We have to first convert the fraction rates into percentage rates. To change a fraction to a percentage, you can divide the numerator by the denominator then multiply the result by 100. Alternatively, you can multiply the numerator by 100 first then divide the result by the denominator of the fraction.

1/2 = 50%

1/3 = 33.33%

Now reviewing this data, we see that a 50% decrease of a price is more than a 33.33% decrease.

The formula for the cost, C, of hiring a DJ for n hours is C = hn + e

a. The formula for the cost, C, of hiring a DJ for n hours is C = hn + e, where h is the hourly fee and e is the equipment setup fee.

n = (C - e) / h

The new formula represents the number of hours the DJ was hired for given the cost, C, and the hourly fee, h.

c. If the DJ charged $550, we can use the inverse formula to find the number of hours she was hired for.
