Mean can also be thought of as average.
Standard deviation is a bit more difficult to describe. It is a statistic that can help measure how spread out the data gets.
Depending on the distribution, data within 1 standard deviation of the mean can be considered fairly common and expected. Essentially it tells you that data is not exceptionally high or exceptionally low.
42. The mean is the total of the numbers divided by the amount of numbers. In this case the amount of numbers is 7 and the mean is 6. That means that the total of the numbers divided by 7 equals 6. To find the total you just do the opposite, multiply 7 by 6 and you get 42.

It is 5.9 meters and 590 centimeters
x= -13 , y=11
Step-by-step explanation:
Using elimination method, make the x variable equal to eliminate the variable
-3x - y = -28
2x+ 3y=7
2(-3x-y =28)
3(2x+3y=7)
-6x - 2y =56
6x +9y=21
Apply addition
7y = 77
y=77/7 = 11
Use the value of y=11 in
2x+ 3y=7
2x +3(11) =7
2x +33 =7
2x=7-33
2x= -26
x= -26/2 = -13
