You have to searh the x values that make f(x) = 0
Factoring this equation is very difficult.
You can divide by x+3 and you will find that the equation can be factored as
(x+3)(x-4)^2
That means that x = -3 and x = 4 make f(x) = 0
Then the points are (-3,0) and (4,0).
8 times 8 is the closest you can get to 71 without going over, since 8 times 9 would be 72.

0.90 x 4 = 3.60 + 2.05 = 5.65

Step-by-step explanation:
A
Answer:
c. confidence/probability
Step-by-step explanation:
The margin of error of a confidence interval is:
M = T*s.
In which T is related to the confidence level and s is the standard deviation of the sample.
In which
z is the zscore that has a pvalue of
.
Before the sample is chosen
We choose our confidence level, which will determine the value of T. So the first answer is confidence.
After the sample is chosen
We are 95% sure that the true mean is in the sample. So the second answer is probability.
So the correct answer is:
c. confidence/probability
