Elena is trying to figure out how many movies she can download to her hard drive. The hard drive is supposed to hold 500 gigabyt
soldi70 [24.7K]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Maximum capacity of hard drive = 500 GB

Space used up = 58 GB

Size per movie = 8GB

Number of movies = x

1)

[(Number of movies * size per movie) + used up space] should be less than or equal to the maximum capacity to f the drive.

From Elena's inequality, the total space taken up by movies + used up space is greater than total capacity of hard drive.

That is ;

[(8x + 58 ≤ 500

8x ≤ 500 - 58

8x ≤ 442

x ≤ 442 / 8

x ≤ 55.25

The maximum number of movies Elena can download is 55

lubasha [3.4K]

Answer:

<h2><u><em>The lengths of the sides of a small cube are = foot. Volume of cube = side x side x side. V = = cubic foot. Number of small cubes that can be packed in the prism = = = = 180 cubes. Hence, 180 cubes can be packed into rectangular prism. Part B: Unit cube volume is 1x1x1 =1 cubic foot. So, 180 cubes will have 180 cubic foot volume.</em></u></h2>

VladimirAG [237]

Answer:

Option C) 0.57

Step-by-step explanation:

We are given the following in the question:

Average, \mu_0 = 260 calories

Standard deviation, \sigma = 35 calories

\mu_1 = 240 calories.

We have to find the Cohen's d effective size.

Formula:

d = \bigg|\dfrac{\mu_1 - \mu_0}{\sigma}\bigg|\\\\d = \bigg|\dfrac{240-260}{35}\bigg|\\\\d = 0.57

Thus, the Cohen's d effective size is 0.57

Thus, the answer is

Option C) 0.57
