Answer:
1.5
Step-by-step explanation:
To find the mean, we must add all of our terms, and then divide by the number of terms.

Solve:

Since we have seven terms, we must divide our total (
), by seven.
÷ 
Solve:
÷ 
Therefore, the mean is 
Answer:
r = 0
Step-by-step explanation:
To solve this for r, add 20 to both sides. The result will be -10r = 0, and so
the solution is r = 0.
For the truth

Answer:
BC = 12, AC = 12, ED = 8, DK = 14, EK = 12
Do you have a picture?? Maybe? I’m not good at these
If the population is proportional to the area of the circle, we can use the variation equation:
P1/r1^2 = P2/r2^2
with
P1 = 19465000
r1 = 5
P2 = 25675000
r2 = ?
19465000 / 5^2 = 25675000 / r2^2
r2 = 5.74 inches<span />
