Answer:

Step-by-step explanation:

Today woman is x, son is y

x-9=3(y-9)

x-9=3y-27

3y-x=18

in 8 years x+8 and y+8 and that sum is 78, so x+y+16=78

x+y=62

x=62-y

so 3y-62+y=18

4y=80

y=20 son

x=42 mother

nine years earlier it was 33 and 11

8 years from now it will be 50 and 28

8 years from now is suppose to = 78 and 50+28=78

Since 8 years from now they the woman is 42 and the son is 20.

A local bank surveyed the status of ASU student accounts and found that the average overdraft was $21.22 with a standard deviati
svlad2 [7]

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
