Yes, that is true, you have to simplify -42/-45 to be able to see if they are equivalant.
Ok there is 7 students in total… the ratio of boys to girls is 5 to 2, so 5 divided by 7 is 0.714%
Calculate rank percentile in Excel

The coordinates of X are (5, 11).
Solution:
Given points of the line segment are P(2, 2) and T(7, 17)
Let X be the point that partitions the directed line segment PT in the ratio 3 : 2
Using section formula, we can find the coordinate of the point that partitions the line segment.
Section formula:

Here,
and m = 3, n =2
Substitute these in the section formula,




X(x, y) = (5, 11)
The coordinates of X are (5, 11).
Here is your answer
D.
π 
REASON:
Formula for volume of sphere
= 4/3×π× r^3
Here, r= 13
So,
volume=4/3×π× 13^3
= 4/3×π× 2197
= 8788/3 ×π
