The tax rate would be around 30.2% so the tax would be around $6,984 per month
1) The population
Is the set of all the terms that the teacher taught this semester and which he wrote down on the note cards and put in the paper bag.
2) The sample is every set of five cards that is selected by each student.
3) I think the sample is representative because all ther terms have the same probability of being selected.
Further, given that the cards are replaced every time all the students will face the same population when they are going to select a sample.
Answer: 0.1587
Step-by-step explanation:
Given : Adult male heights have a normal probability distribution with a mean of 70 inches and a standard deviation of 4 inches.
i.e.
Let x be the random variable that represents the heights of adult males.
Also,
For x= 74 , we have
Then, the probability that a randomly selected male is more than 74 inches tall:-
[using z-value table.]
Hence, the probability that a randomly selected male is more than 74 inches tall = 0.1587

Answer:
10 months
Step-by-step explanation:
Let m represent # of months
Gold's gym charges 150 to sign up and 10 per month
150 + 10m
Fitness express charges no initial fee but charges 25 per month
25m
when will the costs be the same...when will they be equal...so set them equal and solve for m, the number of months
150 + 10m = 25m
150 = 25m - 10m
150 = 15m
150/15 = m
10 = m <==== the cost will be the same in 10 months
150 + 10m ....in 10 months
150 + 10(10) = 150 + 100 = 250
25m...in 10 months
25(10) = 250
so u see, in 10 months, they will both cost $ 250
