A local summer art camp admits kids from ages 5 to age 13. In the summer of 2015, the camp had the following
distribution of ages for its 25 participants:
a. What percent of the kids attending are less than 8 years
old?
b. Which is greater, the mean or the median of this data
set? By how much?
c. What is the interquartile range of this data set? Show
how you calculated your answer.
d. The box plot below shows the distribution of ages at a dance camp. Which of the two camps has the greater
range of ages? Support your answer.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
