Answer:
B or
Lower quartile: 124
Median: 131
Upper quartile: 137
Step-by-step explanation:
To find the median first make the data in order from greatest to least:
118,122,124,129,129,133,135,137,139,142
Then find the middle 2 numbers which are 129 and 133
129+133=262 (divide by 2 to find average) so
median= 262/2=131
To find the Lower quartile find the number in the middle of the first 5 numbers which is 124
To find the Upper quartile find the number in the middle of the second 5 numbers which is 137 so
B or
Lower quartile: 124
Median: 131
Upper quartile: 137
Billy get 5.9% raise after completing first year.
<h3>What is PERCENTAGE?</h3>
A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.
Here, Billy's initial salary = $ 42,500
After raise, salary become $ 45,000
Change in salary = Raised salary - Initial salary
= 45000 - 42500
= $ 2500
% Change = change / initial salary X 100
= 2500 / 42500 X 100
= 0.0589 X 100
≈ 5.9 %
Thus, Billy get 5.9% raise after completing first year.
