The head of maintenance at XYZ Rent-A-Car believes that the mean number of miles between services is 4959 miles, with a standard deviation of 448.If he is correct, what is the probability that the mean of a sample of 43 cars would differ from the population mean by less than111 miles? Round your answer to four decimal places.
Answer:
0.8958
Step-by-step explanation:
Given that:
The mean [tex]\mu[/tex] = 4959
The standard deviation [tex]\sigma[/tex] = 448
The sample size n = 43
[tex]\mu_{\overline x} = \mu = 4959[/tex]
[tex]\sigma __{\overline x}} = \dfrac{\sigma}{\sqrt{n}}= \dfrac{448}{\sqrt{43}}[/tex]
By applying the central limit theorem;
[tex]\overline X \sim N \bigg( \mu_{\overline x} = 4959 , \sigma_{\overline x} = \dfrac{448}{\sqrt{43}}\bigg )[/tex]
The purpose of this question is to calculate the probability that the mean of a sample of 43 cars would differ from the population mean by less than111 miles.
This implies that;
[tex]P( |\mu-\overline x| <111) = p( 4959-111 < \overline X < 4959 +111)[/tex]
[tex]= P( 4848 < \overline X < 5070)[/tex]
[tex]= P \bigg ( \dfrac{ \overline x - \mu_x }{ \dfrac{\sigma}{\sqrt{n}}} < Z < \dfrac{ \overline x - \mu_x }{ \dfrac{\sigma}{\sqrt{n}}} \bigg )[/tex]
[tex]= P \bigg ( \dfrac{4848 -4959 }{ \dfrac{448}{\sqrt{43}}} < Z < \dfrac{5070 -4959 }{ \dfrac{448}{\sqrt{43}}} \bigg )[/tex]
[tex]= P \bigg ( \dfrac{-111 }{ 68.319} < Z < \dfrac{111 }{68.319} \bigg )[/tex]
[tex]= P ( -1.6247< Z < 1.6247 )[/tex]
= P ( Z < 1.627 ) - P(Z < -1.627)
From the standard normal tables
= 0.94791 -0.05208
= 0.89583
≅ 0.8958 to four decimal places.

PLEASE HELP ME IM MARKING ANSWER BRAINLIEST RIGHT NOW!!Mr. Youngbear buys T-shirts in boxes
of 20 for $80 per box. He sells the
T-shirts for $6 each. How much profit
has he made after selling 93 T-shirts?
Step-by-step explanation:
1. Ok so first we need to figure out how many boxes of shirts he bought. In each box there are 20 shirts and he sold 93. So if we round it, he bought about 100 T-shirts. 100 ÷ 20 = 5. So he bought 5 boxes of shirts.
2. Next we need to figure out how much he spent on the shirts. 5*80=400. So he spent $400 dollars on the shirts.
3. We need to find out the amount of money he made from selling the shirts. 6*93=558
4. We need to find the profit so you subtract the total expenses from the total revenue. 558-400= 158. So the profit is $158
Answer: Mr. Youngbear made 158 dollars worth of profit after selling 93 T-shirts.

Last year, a 1.6-gallon container of ice cream sold for $5.99. This year, the same ice cream, now in a 1.2-gallon container, sells for the same price of $5.99. By what percentage was the weight of a container of the ice cream reduced? A. 75% B. 25% C. 60% D. 40%
Answer:
25% is the answer
Step-by-step explanation:
From last year to this year, the weight of the container is reduced by
B. 25%
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Last year, a 1.6-gallon container of ice cream sold for $5.99. This year, the same ice cream is now in a 1.2-gallon container.
So, The amount of icecream increased this year is,
= (1.6 - 1.2) gallons.
= 0.4 gallons.
Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,
= (0.4/1.6)×100%.
= 0.25×100%.
= 25%.

Lee has 3 dog walking customers. Each month he gains another customer. Which arithmetic sequence represents the number of customers he has?
Group of answer choices
a1 = 3; an = an-1 + 1
a1 = 1; an = an-1 + 3
a1 = 1; an = an+1 + 3
a1 = 3; an = an+1 + 1
Given:
Lee has 3 dog walking customers.
Each month he gains another customer.
To find:
The arithmetic sequence that represents the number of customers he has.
Solution:
Initial number of customers = 3
First term : [tex]a_1=3[/tex]
Each month he gains another customer.
Common difference : [tex]d=1[/tex]
Recursive formula of an AP is
[tex]a_n=a_{n-1}+d[/tex]
where, d is common difference.
Substituting d=1, we get
[tex]a_n=a_{n-1}+1[/tex]
So, the required arithmetic sequence is [tex]a_n=a_{n-1}+1[/tex], where [tex]a_1=3[/tex].
Therefore, the correct option is A.
4(2x−9)=4 solve for x
Answer: x=5
Step-by-step explanation:
Distribute the 4 to the 2 and 9 and you will get (8x-36)=4.
Then you'd add the 36 to 4 to get 40.
Lastly you'd divide 8 and 40 to get 5. Hope this helps!!!

how to find the sale price of an item that has been discounted 25%
Answer:
Multiply the normal price of the item by .25 and then subtract that from the normal price.
Step-by-step explanation
[tex]x -(x*.25)[/tex]
x is the item
Step-by-step explanation:
100%-25%= discounted price= 75%
You do the discounted price divided by 75 to find 1%
do that times 100 to find the pre-discounted price.
e.g
find the original price of a sweater when it was on sale of 25%. the sale price is £15.00.
£15.00 = 75%
15.00 divided by 75 = 1% =£0.20
£0.20 x 100 = pre-sale price = £20.00
The price of the sweater before the sale is £20.00.

The life of light bulbs is distributed normally. The variance of the lifetime is 900 and the mean lifetime of a bulb is 520 hours. Find the probability of a bulb lasting for at most 576 hours. Round your answer to four decimal places.
Answer:
0.969
Step-by-step explanation:
Given that:
Mean lifetime (m) = 520 hours
Variance = 900
Hence, standard deviation (s) = √900 = 30
Probability that bulb will last for at most 576 hours
X ≤ 576
Obtain the standardized score :
Using the relation :
Zscore = (x - m) / s
Zscore = (576 - 520) / 30
Zscore = 56 / 30
Zscore = 1.867
P(Z ≤ 1.867) : using the z probability calculator ;
P(Z ≤ 1.867) = 0.96905
Hence, P(Z ≤ 1.867) = 0.969
