this would have to be an inequality equation.
Marathon is 26.2 miles
they get to a hill that is at least 10 miles into the race
26.2-10=16.2
so they have at most 16.2 miles to go
the equation is X<=16.2
Answer:
Solution
Step-by-step explanation:
If im wrong let me know okay!
If im wrong Im sorry Im only 15 and im working here to help
First arrange the data in an order
3, 3, 3, 7, 7, 10, 10, 12, 12, 13, 14, 17, 17, 18, 21
a.) Q1 = (N + 1)/4th item = (15 + 1)/4 = 4th item = 7
Q2 = 2(16)/4 = 16/2 = 8th item = 12
Q3 = 3(16)/4 = 3(4) = 12th item = 17
IQR = (Q3 - Q1)/2 = (17 - 7)/2 = 10/2 = 5
b.) 82nd percentile = 82(16)/100 = 13th item = 17
c.) 12 is the 8th item which is in the middle of the data set, so the percentile rank is 50%
600
Because the tens digit is less than 5, round down to 600
30%
If the price went up to 65 from 50, that is an increase of 15. 15 is 30% of 50.
