Step-by-step explanation:
Answer:
The margin of error for a 90% confidence interval is 16.4
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 25
Standard deviation = 50

Margin of error =

Putting the values, we get,

Thus, the margin of error for a 90% confidence interval is 16.4
Answer:
3a^4
Step-by-step explanation:
The cube root can be written as ^ 1/3
( 27 a ^12) ^ 1/3
We can write ( ab) ^c as a^c * b^c
27 ^ 1/3 a ^12 ^1/3
Rewriting 27 as 3^3
3^3 ^ 1/3 a ^12 ^1/3
We also know that a^b^c = a^(b*c)
3 ^(3* 1/3) a ^(12 *1/3)
3^1 a^4
3a^4
Answer:
14
Step-by-step explanation:
aₙ = a₁ + (n-1)*d
59 = 2 + (20-1) * d
59 = 2 + 19d
19d = 59-2 = 57
d = 3
5th term: a₅ = 2 + 4 * 3 = 14
