The answer is D.
Step-by-step explanation:
Well since there are 4 values calculated then 2 would be above the mean because plus the 2 values above the mean. I don't know if it makes since though.

Answer:
208 minutes = 3.47 hours
Step-by-step explanation:
It takes each person 10.4 minutes for 1 wall. So 20 people would take 208 minutes for 20 people to paint 20 walls
52/5 = 10.4
20 x 10.4 = 208
Answer:
1,000,000 times larger
Step-by-step explanation:
2 x
= 200,000,000
2 x
= 200
200,000,000 divided by 200 is 1,000,000
It can also be solved by subtracting the exponents from 10. Then dividing the two number being put the scientific notation.
= 
2 ÷ 2 = 1
Now solve:
1 x
= 1,000,000
We can use FOIL to solve.
(x + 7)(x + 10)
(x * x) + (x * 7) + (7 * x) + (7 * 10)
x² + 7x + 7x + 70
x² + 14x + 70
Best of Luck!
