Amar surveyed six friends, asking each how many times he or she had ridden in a helicopter. the numbers of times she recorded were 0, 0, 0, 1, 3, and 8.

what is the mean absolute deviation of the number of times?

round to the nearest tenth, if needed.

0

2

2.3

2.5

Hence to the nearest tenth mean absolute deviation  is:

2.3

Step-by-step explanation:

We are given a set of data points as:

The numbers of times she recorded were

0, 0, 0, 1, 3, and 8

on finding the mean we have:

Hence, now we subtract each data point from mean and find their absolute value as:

|0-2|= 2

|0-2|=2

|0-2|=2

|1-2|=1

|3-2|=1

|8-2|=6

Hence now the mean of these absolute value is called Mean absolute Deviation (MAD)

Hence to the nearest tenth mean absolute deviation  is:

2.3

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
