This chart shows the calories of several sandwiches at a restaurant.( 242, 280, 290,290,350,390) find the mean and mean absolute deviation of this set of data, and then describe what the mean absolute deviation represents

Mean= 307

Mean absolute deviation = 42

Meaning:

Mean absolute deviation (42) means average distance between each data point and the mean is 42.

Step-by-step explanation:

We have been given a chart that shows the calories of several sandwiches at a restaurant.( 242, 280, 290,290,350,390).

Now we need to find the mean and mean absolute deviation of this set of data, and then describe what the mean absolute deviation represents.

To find mean, we just need to add the given numbers and divide by total numbers.

Hence Mean= 307

Look at the attached table for calculation

To find deviation, we just find difference between given data values and Mean (307)

To find mean absolute deviation, we again take mean of deviation values as shown in table.

Hence mean absolute deviation = 42

Mean absolute deviation (42) means average distance between each data point and the mean is 42.

repeat the question

step-by-step explanation:

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
