Answer:
The best point estimate for the mean monthly car payment for all residents of the local apartment complex is $624.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
In this question:
We apply the inverse Central Limit Theorem.
The mean monthy car payment for 123 residents of the local apartment complex is $624.
So, for all residents of the local apartment complex, the best point estimate for the mean monthly car payment is $624.
Y=-1/2+1
Hope this helps :)
Answer:
pages
Step-by-step explanation:
Variable:
x = number of pages he has to read on a weekday
x + 30 = The number of pages read on Saturday and Sunday
Meaning that Raoul has to read 59 pages on Wednesday
Answer:
79%
Step-by-step explanation:
He has 100% to start off. If he puts 21% into savings you subtract that from the starting amount. 100 - 21 = 79. Therefore the answer is 79%.
Answer:
Step-by-step explanation:
A.)
Let the equal number of hours be represented by variable h;
The two equations will be as follows;
Jack; 40 +30h
Mark; 50 +25h
Next, equate them;
40 + 30h= 50 + 25h
30h - 25h = 50 - 40
5h = 10
h =10/5
h = 2
Therefore, they charge the same amount at 2 hrs.
B.) The amount charged;
Replace the variable H in any of the two equations above with 2 to solve for the amount.
Equation 40+30h = 40 + (30*2)
=40 + 60
= $100
