Answer:
Given that
Marks of ten friends
23%, 37%, 45%, 49%, 56%, 63%, 63%, 70%, 72% and 82%
Mean = 56
Variance = 284.6
Standards deviation = 16.9
(x`-b/2a)-D/4a
(x`-7)+576
answer! (7;-576)
There are several ways such as
255

/ 7
First put it in the decimal equation
Since there is a decimal in the number being divided(255.5), you move the decimal so that it is a whole number(2555) but since you move the decimal place once, you do the same to the 7 so that it is now 70. So now it's 2555/70 which looks like 365 but then, you have to place the decimal value so that it is now 36.5
This is what you use to divide as shown.
