Answer:
-63
Step-by-step explanation:
This arithmetic progression
The formula is a+(n-1)d
a means the first value
n is the nth term
d is the difference
So a is -5
n is 30
d is -2
So let's substitute
-5+(30-1)-2
-5+(29)-2
-5-58
-63
Therefore the final answer is-63
Just follow the step and the general formula, you will get your final answer
5(x + 1)....distribute the 5 thru the parenthesis...that means multiply the 5 by everything in the parenthesis.
5(x + 1) = 5 * x + 5 * 1 = 5x + 5
Answer:
0.078
Step-by-step explanation:
Margin of error = z√(p(1-p)/n)
Given
p-hat = 0.43
n = 270
z at 99% confidence interval = 2.576
Substitute
MOE = 2.576√0.43(1-0.43)/270
MOE = 2.576√0.43*0.57/270
MOE = 2.576√0.2451/270
MOE = 2.576*0.030129
MOE = 0.078
Hence the margin og error is 0.078
