Step-by-step explanation:
12, 13, 13, 14, 21, 22, 23
Median: 14
Mean: 16.86
The mean reflects the best measure of the center
Answer:
The answer is B. 70
Step-by-step explanation:
First, since K is the midpoint of line segment JL, JK must equal KL.
So, set 9x-1 = 2x+27 and solve.
7x=28 so x=4
Then, since they are asking for JL, using x=4, add together JK and KL.
So, 9x-1+2x+27 = 11x+26 = 11(4) + 26 = 44+26 = 70
Suzy: (7 days)(5/4 miles per day) = 35/4 miles
Gretchen: (7 days)(3 miles per day) = 21 miles
Subtracting, 21 miles less 35/4 miles = 49 miles (difference)
228-12.4%= 199.728
199.728 rounded to the nearest tenth is *199.7*
