31 people
Step-by-step explanation:
Hamzah soccer team is trying to raise the amount of $620 to travel to a tournament in Florida
The soccer team decide to organise a pancake breakfast
Each person that attends the breakfast must pay $20

Answer:
% Change = (87.5 - 125) / 125 * 100%
= -37.5 / 125 * 100%
= -0.3 * 100%
= -30 %
The percent change is -30 % or 30% decrease.
Answer:
c) skewed to the right.
Step-by-step explanation:
We need to remember that is a distribution is skewed to the right then we have the following condition satisfied:
And if is skewed to the left then we have:
If the distribution is symmetric we need to satisfy:
For this case since we have most of the values between 200000 and 500000 when we put atypical values like 15000000 that would affect the sample mean and on this case the sample mean would larger than the sample median because the median is a robust measure of central tendency not affected by outliers.
So for this special case we can say that the 
. And probably the median would be higher than the mode so then we can conclude that the best answer for this case would be:
c) skewed to the right.
Answer:
78 mg
Step-by-step explanation:
370 mg - 110 mg = 260 mg (amount decayed in the 8 total years)
260 mg ÷ 8 years = 32.5 mg decayed per year
32.5 × 9 years (years between 2008 and 2017) = 292.5 mg
370 mg - 292.5 mg = 77.5 mg, rounded to 78 mg
