Roman55 [17]

The information illustrated that A. there is a small difference in the mean number of stray cats placed in homes buy a new lease on life animal clinic each week and the mean number of stray cats placed in homes by no raft staff animal hospital each week.

<h3>What is a mean?</h3>

A mean or average is the ratio of the sum of observations to the number of observations.

For the first case:

Mean = (13*5 + 14*10 + 15*19 + 16*13 + 17*4)/75 = 10.21

For the second case:

Mean =(3*2 + 4*10 + 5*21 + 6*11 + 7*5 + 8*3)/33 = 10.48

Therefore, it should be noted that there is a small difference in the mean number of stray cats placed in homes buy a new lease on life animal clinic each week and the mean number of stray cats placed in homes by no raft staff animal hospital each week.

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = x² + 4x

f(-7) is x = -7

<u>Step 2: Solve</u>

  1. Substitute:                    f(-7) = (-7)² + 4(-7)
  2. Evaluate:                       f(-7) = 49 + 4(-7)
  3. Multiply:                        f(-7) = 49 - 28

send me the dimensions of a square pyramid are shown in the diagram the height of the square pyramid is 7.5 M what is the volume
kolezko [41]

Answer:

volume = 202.5 cubic meters

Step-by-step explanation:

We need to find volume of square pyramid, given 7.5m as the height and base of 9m each side (square base).

<em>The image is attached.</em>

<em />

We can use the formula to find volume of square pyramid. The formula is:

V=\frac{1}{3}x^2h

Where

x is the base (here it is 9 meters)

h is the height (which is given as 7.5 meters)

We substitute and find the volume:

V=\frac{1}{3}x^2h\\V=\frac{1}{3}(9)^2(7.5)\\V=202.5

The volume = 202.5 cubic meters
