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

Answer:
Step-by-step explanation:
Given that transitor has a 2% defective rate, need to calculate the probability that the 10th transistor produced is the first with a defect.
The probability function is p(x=k) = (1-p)^(n-1) * p
p = (1-defective rate)^(n-1) * defective rate; n=10
p = (1-0.02)^9 * 0.02 = 0.98^9 * 0.02 = 0.01666
