Answer:
a summary is an average and an average is mean
Step-by-step explanation:
to get the mean add all the cakes sold together then divide by number of years
21+28+19+26+21=115
115/5=23
so....
first one: mean
second one: 23
Let us try and solve it analytically. We have that the side=x+3 together with the short side=s and the diagonal=x+4 satisfy the Pythagorean Theorem. Then we have that

. This yields

which yields s^2=2x+7, hence a) is the correct answer.
Answer:
b = 3/4
Step-by-step explanation:
Hi!!!
You want the value of B. To get that, we have to divide both sides by 16:


Thus the answer to your question is
.
<u>Check:</u>
3/4 * 16 = 3 * 4 = 12.
12 = 12
So we are correct!!!
