The answer would be A. 5 because each time you add 5 hope this helps and make me branliest please(:
Answer:
a. .92
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error of the interval is:
The lower bound is the point estimate subtracted by the margin of error.
The upper bound is the point estimate added to the margin of error.
Point estimate:
The confidence interval is symmetric, so it is the mean between the two bounds.
In this problem:
Sample of 400, which means that
Margin of error is the estimate subtracted by the lower bound. So
We have to find z.
has a pvalue of 0.96.
This means that:
Confidence level:
So the correct answer is:
a. .92
A.
Step-by-step explanation:
Range of a function is the value that we get when a function is solved.
Say, f(x) = y.
We say this "set of x is domain" whereas "set of y is range".
Suppose,
set A = {1,2} & set B = {1,2,3} & f(x) = y
Let,
f(1) = 1, & f(2) = 2.
What we get is that there is no x for 3.
We say this fact by "set A is domain" & "set B is co domain" & set {1,2} (output) is range.
245,195,145,95,45
explanation: 245-195 is 50 so you subtract 50 from 195 and get 145 and subtract 50 from that and get 95
F = final amount = unknown
P = 7000 is the principal (amount loaned)
i = 0.05 is the decimal form of 5% interest rate
t = 3 years go by
Plug those three values into the formula below and simplify
F = P*(1+i)^t
F = 7000*(1+0.05)^3
F = 7000*(1.05)^3
F = 7000*(1.157625)
F = 8103.375
F = 8103.38
<h3>Answer: Choice A) $8,103.38</h3>
