8,14,20,26
8 to 14 is 6
14 to 20 is 6
20 to 26 is 6
The next term will be 26 + 6 = 32
Because there is a gap of 6 between each number

Answer:
31x³-60x²+7x-75
Step-by-step explanation:
(30x³-49x³+7x)+(50x³-60x²-75)
(-19x³+7x)+(50x³-60x²-75)
-19x³+50x³+7x-60x²-75
31x³-60x²+7x-75
Answer: 18
Step-by-step explanation:
The formula to find the minimum sample size is given by :_

, where
= population standard deviation.
z*= critical z-value.
E= Margin of error.
Given : 
E= ± 8
We know that critical value corresponding to 99% confidence level = z*=2.576 [Using z-table]
Then, the required sample size would be :


[Round to next integer.]
Hence, the required minimum sample size = 18
