My sister needs on this? can anyone give an explanation and answer/show work? you'll be brainliest if you do! you so much for taking the time : ) v felicity recorded the number of laps she swam each month for 7 months. her data is shown. 112,134,150,98,120,68,116 which is the mean absolute deviation to the nearest whole number of felicity's lap data? a.16 b.18 c.20 d.36

Answer C

to calculate mean absolute deviation, we need to use the formula = (∑|x-mean|)/n

where x is each term given in data set

n is number of terms = 7

mean = sum of terms / n = (112+134+150+98+120+68+116)/7 = 114

now find (∑|x-mean|) = 138

MAD = (∑|x-mean|) / n = 138 /7 = 19.714 = 20

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

c ) y = 2.5 x - 26.25
