Answer:
here are two possible solutions
Step-by-step explanation:
Every confidence interval has associated z value. As confidence interval increases so do the z value associated with it.
The confidence interval can be calculated using following formula:

Where

is the mean value, z is the associated z value, s is the standard deviation and n is the number of samples.
We know that standard deviation is simply a square root of variance:

The confidence interval of 95% has associated z value of <span>1.960.

Answer:
If you are looking for x your answer will be x=2
Use slope formula
(y1-y2)/(x1-x2)
(16 - -19)/(0 - 4) = 35/-4
Answer:
8π(2.5)^2
Step-by-step explanation:
volume = π * r^2 * h
v = π * (2.5)^2 * 8
