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.

Answer:
f(-7) = 21
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>
- Substitute: f(-7) = (-7)² + 4(-7)
- Evaluate: f(-7) = 49 + 4(-7)
- Multiply: f(-7) = 49 - 28
- Subtract: f(-7) = 21

We can use the formula to find volume of square pyramid. The formula is:
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:
The volume = 202.5 cubic meters
