The number of cubes in the rectangle prism will be 320. Then the correct option is D.

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as

V = L x W x H

A right rectangular prism is completely filled with small cubes. Each small cube has edges that are 1/4 inches long. The volume of the prism is 5 inches.

Let 'n' be the number of cubes. And all the sides of the cube are congruent. Then the volume of each cube is calculated as,

Volume of cube = (1/4) x (1/4) x (1/4)

Volume of cube = 1 / 64 cubic inches

The volume of the rectangle and the volume of small 'n' cubes will be equal. Then we have

Volume of 'n' cube = Volume of a rectangle

(1 / 64) n = 5

n = 5 x 64

n = 320

The number of cubes in the rectangle prism will be 320. Then the correct option is D.

Complete Question

A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthorn wand has a price of 45.20. What proportion of wand prices are lower than the price of the blackthorn wand? You may round your answer to four decimal places

Answer:

0.1151

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = $45.20

μ is the population mean = $50

σ is the population standard deviation = $4

We are solving for x < 45.20

Hence:

z = 45.20 - 50/4

z = -1.2

Probability value from Z-Table:

P(x<45.20) = 0.11507

Approximately to 4 decimal places = 0.1151

Therefore, the proportion of wand prices that are lower than the price of the blackthorn wand is 0.1151

Answer:

18x ≥ 160

Step-by-step explanation:

Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week.

Let the number of hours = x

At least = Greater than or equal to

Slope intercept form

= y = mx + c

y = $160

Hence

10x + 8x ≥ 160

18x ≥ 160

Answer:

Actually, 20 divided by 2 1/3 equals 8.57 repeating (8.571428...), which can be rounded to 8.57 to two decimal places.

To see why, we can convert the mixed number 2 1/3 to an improper fraction:

2 1/3 = (2 * 3 + 1) / 3 = 7/3

Then, we can rewrite the division as a fraction and simplify:

20 / (7/3) = 20 * (3/7) = 60/7 = 8.571428...

So, 20 divided by 2 1/3 is approximately 8.57.

Answer:

The runner with a mean running time of 6.2

Step-by-step explanation:

The value range parameters of the three runners are;

The mean running time of the runner, A = 6.2

The mean running time of the runner, B = 7.4

The mean running time of the runner, C = 6.9

The interquartile range of the runner, A = 1.1

The interquartile range of the runner, B = 0.02

The interquartile range of the runner, C = 0.08

Whereby the number of running times for the 3 runners is large, and with the assumption that distribution of the mean is normal, we have

The mean = The mode of  the data

Therefore, the minimum, and maximum running time of the runners are;

Runner A;

Minimum running time = 6.2 - 1.1 = 5.1

Maximum running time = 6.2 + 1.1 = 7.3

Runner B;

Minimum running time = 7.4 - 0.02 = 7.38

Maximum running time = 7.4 + 0.02 = 7.42

Runner C;

Minimum running time = 6.9 - 0.08 = 6.82

Maximum running time = 6.9 + 0.08 = 6.98

The fastest runner has the lowest running time;

Therefore, the fastest runner is runner A with a mean running time of 6.2  with a minimum running time of 5.1
