Answer:
The answer is 0.2mile
Step-by-step explanation:
The vertical height of the building, which is 630ft, is opposite the angle of elevation (30°).
While the horizontal distance to the tower is adjacent to the building. So, we take the tangent of the angle of elevation in terms of this unknown distance (x) and the vertical height.
So,
Tangent = opposite ÷ adjacent
Tan30° = 630ft ÷ x
x = 630ft ÷ tan30°
x = 1091.192ft
But,
1 mile = 5,280ft
1091.192ft = (1/5280) x 1091.192
= 0.2mile
This will go -7/2,-2.1, square root of 9, 3.5,last will be square root of 5

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
