Answer:
Students have a choice between taking a test on paper or on the computer. Mrs. Gazi graphed the relationship between the number
of students taking the test on the computer and the number of test pages she would need to print.
(graph below)
What feature of the graph represents how many pages Mrs. Gazi would need to print if none of the students take the test on the computer?
a) slope
b) x-intercept
c) y-intercept
d) none of the above

Answer:
1120°
Step-by-step explanation:
Use the sum of interior angles formula:
Where n is the number of sides.
In a nonagon, there are 9 sides, substitute 9 for n:
Since our nonagon is a regular nonagon, all 9 angles measure the same, so each angle measures:
Subtract 140 from 1260:
Answer:
0.003
Step-by-step explanation:
By formula we know that:
z (x) = (x - m) / [sd / sqrt (n)]
where x is the value we want to know (60,000), m is the mean (63500), sd is the standard deviation (6100) and n is the sample size (35).
Replacing we have:
z (60000) = (60000 - 63500) / [6100 / sqrt (35)]
z = -3.39
If we look in the normal distribution table (attached), we have that the probability is 0.0003.
