Answer:
4.4
Step-by-step explanation:
Data set = 79, 93, 92, 86, 90
Xmean = (79 + 93 + 92 + 86 + 90)/5
= 440/5
Xmean = 88
MAD =
(79 - 88) + (93 - 88) + ( 92 - 88) + ( 86 - 88) + ( 90 - 88)/ 5
=
(9) + (5) + (4) + (2) + (2)/ 5
=
22/5
Mean Absolute Deviation = 4.4

Answer:
12 hits
Step-by-step explanation:
Let x be the number of hits needed
1 hit equals an at-bat.
(45+x)hits / (130+x)at-bats = 0.4
(45+x) = 0.4(130+x)
45 + x = 52 + 0.4x
45 - 52 = 0.4x - x
-7 = -0.6x
x = -7/-0.6
x = 11.667
x = 12(approximately)
12 hits are necessary since there are no fraction of hits
