Find the mean, median, and mode of the data set. round to the nearest tenth. {2, 10, 6, 9, 1, 15, 11, 10, 15, 13, 15}
a. mean = 9.7, median = 10, mode = 15b. mean = 8.9, median = 10, mode = 8c. mean = 9.7, median = 8, mode = 15d. mean = 8.9, median = 10, mode = 15

A.

Step-by-step explanation:

1, 2, 6, 9, 10, 10, 11, 13, 15, 15, 15

Mean: 1 + 2 + 6 + 9 + 10 + 10 + 11 + 13 + 15 + 15 + 15 = 107/11 = 9.7

Median: 10

Mode: 15

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
