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

Answer:
y=7
Step-by-step explanation:
Option A he would be paid:
$15 per session
Option B he would be paid:
$20 per session
Equations
A: Y = 15x + 17250
B: Y = 20x + 14000
When X = 650 the Y values of A and B are equal.
<em>After 650 training sessions, they would be equal.</em>
We are given the expression (5v² + 3v + 9) - (4v² + 2v - 5) + (-8v² - 8v + 8), and are told to simplify. First, we can use the distributive property to get rid of all the paranthesis. This gives us 5v² + 3v + 9 - 4v² - 2v + 5 - 8v² - 8v + 8. Now, just combine like terms. This gives us -7v² - 7v + 22, which is our answer. Hope this helps and have a phenomenal day!
