Answer: 1692
Step-by-step explanation:
Formula to find the sample size :
Given : Confidence level : 
⇒ significance level =
z-value for 90% confidence interval (using z-table)=
Prior estimate of the population proportion (p) of customers who keep up with regular vehicle maintenance is unknown.
Let we take p= 0.5
Margin of error : E= 2%=0.02
Now, the required sample size will be :
Simplify , we get
Hence, the required sample size = 1692
56 6 repeating when rounded to the nerest .1 is 56.7
Subtracting a value from the exponent shifts the graph to the right.
So if you subtract 3, the graph would shift 3 units to the right.
Sometimes...
2^-3 = 1/(2^3) = 1/8
-2^-3 = 1/(-2^3) = -1/8
What are all of the x-intercepts of the continuous function in the table? (0, 8) (–4, 0) (–4, 0), (4, 0) (–4, 0), (0, 8), (4, 0)

The answer would be (–4, 0) (–4, 0), (4, 0) (–4, 0) and (4, 0)
You would be looking for anything that is on the X access on the coordinate plan, so it would somewhat have to be a straight line, the way you can find that is (x, y) so whatever is in X will be your answer!
