Mean is when you add all of them together and divide by the amount of data you collected. Mean is considered the average. So, all of them added together would be 14. Divide that by 7. You should get 2 and that is the average.
Answer:
The answer to your question is (g°f)(x) = 7
Step-by-step explanation:
Data
g(x) = 3x - 2
f(x) = x + 5
(g°f)(-2)
Process
1.- Evaluate g(x) on f(x)
(g°f)(x) = 3(x + 5) - 2
-Expand
(g°f)(x) = 3x + 15 - 2
-Simplify
(g°f)(x) = 3x + 13
2.- Evaluate (g°f)(x) on -2
(g°f)(-2) = 3(-2) + 13
-Expand
(g°f)(-2) = -6 + 13
-Simplify
(g°f)(x) = 7
You can cut 15.4 pieces or rounded to 15 pieces just take 12.32 and divide by 0.8 giving you 15.4
Divide the amount he has to pay off with the 8 months. That is 200 divided by 8 which is 25. He has to pay 25 each month.
PB and PA make two sides a rhombus. Since the lengths of the short sides of a rhombus are equal— this also applies for the long sides— PB=PA
PA = 8
Good luck!
