<h3>Answer: B) 31.348</h3>
======================================
Work Shown:
We will never use the alpha = 0.05 value when computing the test statistic. So we can ignore alpha for this particular problem.
-------
n = 40 is the sample size.
s = 2.6 is the sample standard deviation
= sigma = 2.9 is the population standard deviation (ie the claimed standard deviation for all the pay phones)
Test Statistic for chi-square

1)1,2,3,4,5,6
2)1/2
3)1/2
4)1/3
5)5 OR LESS THAN FIVE =1/6
ONLY LESS THAN FIVE (EXCLUDING FIVE)=4/6=2/3
Answer:
4/9
Step-by-step explanation:
8/2=4
18/2= 9
I believe your answer is 8.
Three times a number less than twice the number and nine is seventeen can be written as: 3n - 2n + 9 = 17
Solve for n as follows:
3n - 2n = n
n + 9 = 17
17 - 9 = 8
Hope this helps! :)
Point = (0, 56)
Slope = 1
This is where you would use point slope.
y - y1 = m(x - x1)
y - 56 = 1(x - 0)
y - 56 = x
y = x + 56
Answer is A.
