Answer:
Step-by-step explanation:
We'll look for a line with the form of y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).
A parallel line will have the same slope as the reference line, For y=3x-8, the slope is 3. We can write:
y =3x + b for the new line. We need a value of b that will cause the line to include point (6,-4). To find a b that will work, simple use the given point in the above equation and solve for b:
y =3x + b
-4 =3(6) + b for (6,-4)
-4 =18 + b
b = -22
The parallel line that goes through point (6,-4) is y = 3x - 22

Answer:
A sample size of 61 will produce a margin of error of 9% with 90% confidence level
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 confidence interval is:
For this problem, we have that:
90% confidence level
So , z is the value of Z that has a pvalue of , so .
What sample size will produce a margin of error of 9% with 90% confidence level
This is n when M = 0.09. So
A sample size of 61 will produce a margin of error of 9% with 90% confidence level
Answer:i believe its 3 correct me if im wrong
Step-by-step explanation:
Answer:
There are 78 apples in the bushel that are not granny smith apple.
Step-by-step explanation:
We are given the following in the question:
Number of apples in the bushel,n = 104
Probability of a granny smith apple from The bushel = 25%
P(Granny smit apple) =
Thus, probability thta the apple is not a granny smith apple is
P( Not a granny smit apple) =
Number of apples that are not granny smit apple =
Thus, there are 78 apples in the bushel that are not granny smith apple.
