Answer:
Hence, the minimum required sample size (n) should be = 1692
Step-by-step explanation:
Solution:-
- The estimation error, E = 2%
- The confidence level, CI = 90 %
- Since the proportion of the positive lab tests for prostate cancer are actually proven correct through subsequent biopsy are unknown we will assume the corresponding proportion to be p = 0.58
- The required sample size is a function of confidence value and error of estimation (E):
Where,
- The critical value of the confidence level = 90% would be:
significance level ( α ) = 1 - CI = 1 - 0.90 = 0.1
Z-critical = Z_α/2 = Z_0.05 = 1.645
- The required sample size (n) can be calculated:
- Hence, the minimum required sample size (n) should be = 1692
Given function is
Now question says to find the graph that shows the axis of symmetry for the given function.
Graph is missing but I can help you to find the correct graph.
Given equation is in the vertex form whose formula is given by
Comparing given function with above formula, we get:
a=1, h=2 and k=1.
For the vertex formula , we know that axis of symetry is given by equation:
x=h
So for the given function, axis of symmetry will be x=2
Graph of x=2 will be a vertical line crossing x-axis at x=2
So you just need to find the graph from given choices which contains a vertical line crossing x-axis at x=2.

Answer:
exponential growth by 1600
Step-by-step explanation:
The discount is $100 -85 = $15. As a fraction of the original price, the discount is
$15/$100 = 15/100 = 15%
_____
It can be helpful to think of "%" as another way to write "/100".
