If a trench is 102’-6” long by 5’-4” wide and 3’-3” deep, what is the volume of the soil that was removed per cubic feet?
zzz [600]

Considering that the trench is modeled by a rectangular prism, the volume that was removed is 1776 cubic feet.

The volume of a <u>rectangular prism of length l, width w and height h</u> is given by:

V = lwh

In this problem, we want the measures in feet, and considering that 1 feet is 12 inches:

  • The length is of 102' 6''(102 feet and 6 inches), hence l = 102.5.
  • The width is of 5' 4'', hence w = 5.33.
  • The depth(height) is of 3' 3'', hence h = 3.25.

Then:

V = lwh = 102.5(5.33)(3.25) = 1776

The volume that was removed is 1776 cubic feet.

<h3>What is expected value?</h3>

The expected value is the long term average of the data or the mean of the data.

In order to better decide how to market a new line of clothing, Mary is researching the demographics of the customers of a certain clothing store.

She counted the number of customers who visited the store over the course of a month, and found out how many of the customers were high school students.

Her collected data is in the table below.

  • Week                1          2         3            4
  • Customers    2,848    3,141    3,861    3,911
  • Students       2,033    1,937   2,076    1,721

Mary predicts that the store will see 4,238 customers next week.

From using the long term mean value calculator for the provided data, the predicted value of the next week we get as 2392.

Hence, the number of high school students which should the store expect next week, Mary predicts that the store will see 4,238 customers next week is 2392.

timurjin [86]

Answer: Caroline = 225

Step-by-step explanation:

Let Sarah be x

Caroline will be 3x

Bridget will be 2(3x) = 6x

x + 3x + 6x = 750

10x = 750

x = 750 / 10 = 75

Caroline gets 3x = 3 * 75 = 225
