Find the mean absolute deviation of the set of data 3,8,10,12,15

inn [45]

Answer:

3.28

Step-by-step explanation:

find the mean of all the numbers

3 + 8 + 10 + 12 + 15 = 48

48/5=9.6

so the mean of all the numbers is 9.6

now subtract 9.6 from all the numbers

|3 - 9.6| = 6.6

|8 - 9.6| = 1.6

|10 - 9.6| = .4

|12 - 9.6| = 2.4

|15 - 9.6| = 5.4

Find the mean/average of the new values

6.6 + 1.6 + .4 + 2.4 + 5.4 = 16.4

16.4/5 = 3.28

What is 1/144 as an expression using a negative exponent

MrRissso [65]

ANSWER

${12}^{ - 2}$

EXPLANATION

The given expression is

$\frac{1}{144}$

This is the same as:

$\frac{1}{12 \times 12}$

In index notation, we write this as

$\frac{1}{ {12}^{2} }$

To write this as a negative index, we use the property:

$\frac{1}{ {a}^{m} } = {a}^{- m}$

This implies that;

$\frac{1}{ {12}^{2} } = {12}^{ - 2}$
