If x = 7 we just substitute all the x's by seven, so our equation stays like this:
5 - 3(7 - 1)
Now we solve it:
5 - 3(7 - 1) =
5 - 3(6) =
5 - 18 =
-13

Calculate the standard deviation for each data set:
Sample A = 1.246
Sample B = 2.924
The smaller the deviation the closer the data set is, the larger the deviation the more widespread the data set is.
Sample B has a larger deviation so the spread of the data is wider.
The temperature changed steadily over the 6 hours, which means that it changed the same amount of degrees every hour. It changed -18 degrees in 6 hours.
Divide the temperature change by the number of hours.
-18 ÷ 6 = -3
The change in temperature per hour is -3°.
The number is 5
x + 4 = 19 - 2x

3x + 4 = 19
-4 -4
3x = 15
