Answer:
22
Step-by-step explanation:
mean is calculated as
mean = 
Given the mean of 12 numbers is 20 , then
= 20 ( multiply both sides by 12 )
sum = 240
Given the mean of 8 numbers is 25 , then
= 25 ( multiply both sides by 8 )
sum = 200
Total sum of the 20 numbers = 240 + 200 = 440, then mean of 20 numbers is
mean = 
= 22
125

Answer:
-28
Step-by-step explanation:
If y = 98 when x is 14, y is always seven times x. We know this because x = y/7.
So if Y is seven times bigger, -4 * 7 = -28

Answer:
The answer is C, 296. 73
Step-by-step explanation:
Top Surface Area = π×4.52
= 63.617251235193 inches2
Bottom Surface Area = π×4.52
= 63.617251235193 inches2
Lateral Surface Area = 2π×4.5×6
= 169.64600329385 inches2
Total Surface Area = 296.88050576424 inches2
