Answer:
9/49
Step-by-step explanation:
The maximum number of mosquitoes would exist if 7.5 inches of rain fell.
We can find that by looking for the maximum value in the equation. This value always falls at the vertex. The x-value of the vertex (which is what we are looking for) can always be found through the equation -b/2a, in which a is equal to the coefficient of x^2 (-1) and b is equal to the coefficient of x (15).
-b/2a
-(15)/2(-1)
-15/-2
7.5
Answer:
5/2 0r 2 and a half
Step-by-step explanation:
first I would find all the ways to make 9
6+3=9
5+4
then I would find all the ways to make 10
6+4=10
5+5=10
then I would find all the ways to make 11
6+5
then I would find all the ways to make 12
6+6=12
then add the number of possibilities
9 + 10 + 11 + 12 = 6
There are 6 different ways to make a sum of 9 or more
