Find the mean and the mad. [note: type your answers as decimal numbers, rounded to the nearest tenth.]

135, 160, 145, 155, 170, 150, 142

mean :

mad(mean absolute deviation):

Part 1) The mean is 151

Part 2) The mean absolute deviation (MAD) is 9.1

Step-by-step explanation:

we have

set of data

step 1

Find the mean

Sum all the values and divide by the number of values

step 2

 Determine the  absolute value of subtract the mean from each value

step 3

Find the mean of those distances

----> this number is called the mean absolute deviation (MAD)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
