Answer:
You will need to sample at least 3108 students.
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
.
In this problem, we have that:

99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The margin of error is:

How many students will I need to survey if I want to estimate, with 99% confidence, the true proportion to within 2%?
You need a sample size of at least n.
n is found when M = 0.02. So







You will need to sample at least 3108 students.
The probability will be the same on each roll.
P(6) = 1/6 no matter how many times you roll the die.
A is located at (-3,-5) B is located at (1,-9)
-3 + 1 = -2/2 =-1
-5 + -9 = -14/2 = -7
midpoint is (-1,-7)

Step-by-step explanation:
(-14w) - (-3) - (-5w) equals
-9w + 3
or if what you're saying is
-14w - 3 - 5w it equals
-19w - 3
or if what youre saying is
(-14w - 3) - 5w it equals
-19w - 3
