Answer:
124.75
Step-by-step explanation:
Lets X be aleatory variable for iq scores. Here, wee need a value α such that, the probability that X is greater than α is higher than 0.95. This is:
P(X > α)=0.95
As X distributes normal, if we subtract the mean and divide y its std. dev. it will distribute normal with mean 0 and sts. dev. 1, which permits us to use the normal distribution table to solve it. Doing so:
P([X - 100]/15 > [α-100]/15)=0.95
Using the normal table, we need to look for the value that gives us a probability on 0.95, an it it 1.65.
So, 1.65 must be equal to [α-100]/15 :
1.65 = [α-100]/15
Multiplying both sides by 15:
24.75 = α-100
Summing 100 in both sides:
124.75 = α
So, for scores equals or greater to 124.75 you will be in the top 5% scores.

Answer:
375 lines
Step-by-step explanation:
Total ounces of rain water in the barrel = 3,750 ounces
Measurement lines in the barrel = 10 ounces per line
how many lines did the water reach?
Number of lines the water reach = Total water in the barrel / measurements per line
= 3,750/10
= 375 lines
The water in the barrel reach 375 lines
