<span>log(x-3)+log(x) = 2 + log(x+2)
---------------------------
log[(x-3)x] - log(x+2) = 2
-----
log[(x^2-3x)/(x+2)] = 2
----
(x^2-3x)/(x+2) = 2^2
-------
x^2-3x = 4x+8
x^2 - 7x - 8 = 0
Factor:
(x-8)(x+1) = 0
Positive solution:
x = 8</span>

Answer:
If the soccer coach wants to know how many students made 15 or more goals then she should use the histogram because it is split in to different ranges so it’s easy for her to know how many students made 15 or more goals. If the soccer coach wants to know the least number of goals made she should use the dot plot because that shows the specific number of goals each student made while the histogram only gives an range.
PXrXt /100 is the formula
