What is the mean absolute deviation (mad) of the data set? {2, 5, 6, 12, 15} enter your answer in the box.

To find the MAD

Step 1 : find the mean of the given data

Data : (xi) : 2, 5, 6, 12, 15

Mean = μ = (2 + 5 + 6 + 12 + 15)/5

Mean = μ = 40/5 = 8

Step 2 : find the difference between each data value and the mean

(xi - μ) = (2-8) , (5-8), (6-8), (12-8) , (15-8)

(xi - μ) = -6, -3, -2, 4,7

Take absolute value of each difference

|(xi - μ) | = 6,3,2,4,7

∑|(xi - μ)| = 6 + 3 + 2 + 4 + 7 = 22

MAD of the data set = 1/5∑|(xi - μ)|

MAD of the data set = 22/5

MAD of the data set = 4.4

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
