You work at a local grocery store. Your paychecks over the past 6 weeks were $56.05, $41.50, $22.50, $52.90, $49.85 and $31.00. Find the mean, median and mode.
Answers
Mean is the average of all the paychecks, so it will be: (56.05 + 41.50 + 22.5 + 52.9 + 49.85 + 31)/ 6
The mean is: $42.30. So on average she earns $42.30 each week.
We can find the median by arranging from smallest to larges so: 22.5, 31, 41.5, 49.85, 52.9 and 56.05. Since we have an even number of entries, we will take the average of the middle two entries: (41.5 + 49.85)/2
So the median is: 45.68 (rounded to the nearest tenth)
Mode is the number that appears the most in a given set. In this set we can see, that no number is repeated. Therefore there is no mode.

What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of kids = 3
Number of kids who sang = 2
The number of kids who do notsing.
= 3 - 2
= 1
The percentage of kids who do not sing.
= 1/3 x 100
= 33.33%
Thus,
33.3% do notsing in the talent show.

The percentage is the change with respect to the original thus the percentage increase in her pay will be 20%.
What is the percentage?
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicatinghundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Originalamount = $10
Increased pay = $12
% increase = (12 - 10)/10 x 100
⇒ 20%
Hence "The percentage is the change with respect to the original thus the percentage increase in her pay will be 20%".
