Answer:
3n + 8 < 5n
n > 4
Step-by-step explanation:
Let
n = cost of viewing videos
Plan A: $3 per video viewed, plus a flat rate of $8 per month
Total cost for plan A = 3n + 8
Plan B: $5 per video viewed and no additional flat rate
Total cost for plan B = 5n
Plan A is less than the cost of viewing n videos using Plan B
The inequality
3n + 8 < 5n
8 < 5n - 3n
8 < 2n
8/2 < n
4 < n
n > 4

Answer: the probability of a student being overdrawn by more than $18.75 is 0.674
Step-by-step explanation:
Since the bank overdrafts of ASU student accounts are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = bank overdraft of Asu students.
µ = mean
σ = standard deviation
From the information given,
µ = $21.22
σ = $5.49
We want to find the probability of a student being overdrawn by more than $18.75. It is expressed as
P(x > 18.75) = 1 - P(x ≤ 18.75)
For x = 18.75,
z = (18.75 - 21.22)/5.49 = - 0.45
Looking at the normal distribution table, the probability corresponding to the z score is 0.326
Therefore,
P(x > 18.75) = 1 - 0.326 = 0.674
