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
Please don’t try searching up that link the same person did the same to me on my question
y = 3x-4
You need to find the radius. It is half the diameter
The radius is 2.5
C=2 pi r
C=2 times 2.5= 5. 5 times pi= 15.7
The answer is 15.7
The square root of 3 plus the square root of 2 =3.14626
