2x+2y =50
2(7)+ 2(3)=50
14+6 =50
20=/=50

This is false because when you substitute the variables with their numbers and then multiply and add, your answer does not equal 50

Well we just have to plug in x for 7 and y for 3 
given our equation..
2x + 2y = 50
when x = 7 
and y = 3 

2(7) + 2(3) = 50 

Now we know that 2 x 7 = 14 
and that 2 x 3 = 6 
Now plug those in 

14 + 6 = 50
now 14 + 6 = 20 
20 = 50? 
NOPE 20 does not equal 50 

So your answer is FALSE. 

Hope you have a lovely day :)

The surface area would be 150cm and the volume would be 125cm. To get volume you do 5 cubed to get the answer 125. To get surface area you would do 5 multiplied by 5 multiplied by the cubes 6 sides to get 150.

The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

<h3>What is Mean?</h3>

Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.

<h3>What is the mean absolute deviation?</h3>

Mean refers to the average of the observation and deviation means the variation from the present standard.

Given

Robin’s scores: 99, 108, 102, 107, 119

Mean = 107

MAD = 5.2

Evelyn’s scores: 125, 137, 138, 145, 145

Mean = 138

MAD = 5.6

The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

More about the mean and the mean absolute deviation link is given below.
