Answer:

21

Step-by-step explanation:

Old A: 6    New A: 9

Multiply 6 by 1.5 to get 9.

Therefore multiply 14 by 1.5 as well, which gives you 21.

Answer:

21

Step-by-step explanation:

The equation for direct proportion is

A = kB

We know A and B

6 = k (14)

Divide by 14

6/14 = 14k/14

3/7 = k

Rewriting

A = 3/7 B

Given A =9

9 = 3/7B

Multiply each side by 7/3 to isolate B

7/3 * 9 = 7/3 *3/7 B

21 = B

What whole number dimensions would allow the students to maximize the volume while keeping the surface area at most 160 square f
ycow [4]

Answer:

The whole number dimension that would allow the student to maximize the volume while keeping the surface area at most 160 square is 6 ft

Step-by-step explanation:

Here we are required find the size of the sides of a dunk tank (cube with open top) such that the surface area is ≤ 160 ft²

For maximum volume, the side length, s of the cube must all be equal ;

Therefore area of one side = s²

Number of sides in a cube with top open = 5 sides

Area of surface = 5 × s² = 180

Therefore s² = 180/5 = 36

s² = 36

s = √36 = 6 ft

Therefore, the whole number dimension that would allow the student to maximize the volume while keeping the surface area at most 160 square = 6 ft.

Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Write a probability model for this ex
allsm [11]

Answer:

We estimate to have 8.33 times the number 6 in 50 trials.

Step-by-step explanation:

Let us consider a success to get a 6. In this case, note that the probability of having a 6 in one spin is 1/6. We can consider the number of 6's in 50 spins to be a binomial random variable. Then, let X to be the number of trials we get a 6 out of 50 trials. Then, we have the following model.

P(X=k) = \binom{50}{k}(\frac{1}{6})^k(\frac{5}{6})^{50-k}

We will estimate the number of times that she spins a 6 as the expected value of this random variable.

Recall that if we have X as a binomial random variable of n trials with a probability of success of p, then it's expected value is np.

Then , in this case, with n=50 and p=1/6 we expect to have \frac{50}{6} number of times of having a 6, which is 8.33.
