Here, we are required to find how many hours per week does Lindsey need to study if she wants to have an average of at least 90
Lindsey needs to study for at least 15.25 hours to have an average of 90
Given expression:
4(h + 11) – 15
Where,
h = number of hours
For Lindsay to have at least 90
4(h + 11) – 15 = 90
open parenthesis
4h + 44 - 15 = 90
4h + 29 = 90
4h = 90 - 29
4h = 61
Divide both sides by 4
h = 61/4
h = 15.25 hours
Therefore,
Lindsey needs to study for at least 15.25 hours to have an average of 90

we know that
The probability that a point in the square below is in the shaded region, is equal to divide the area of the shaded region by the area of the square
step 1
Find the area of the shaded region
The area is equal to the area of the square minus the area of the circle
we have
---> length side of the square
----> the radius is half the diameter
assume
substitute
step 2
Find the area of the square
we have
---> length side of the square
substitute
step 3
Find the probability
