Using the z-distribution, it is found that the margin of error of the confidence interval is:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In this problem, it is stated that the population standard deviation is known, thus, the z-distribution is used.
The margin of error of a z-confidence interval is given by:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which:
z is the critical value. [tex]\sigma[/tex] is the population standard deviation. n is the sample size.A similar problem is given at https://brainly.com/question/25214883

kia worked 30 hours and 15 minutes this weekend . if she makes $15.60 per hours ,how much did she make?
Answer:
$471.90 dollars
Step-by-step explanation:
First, we need to find out how many hours she's working.
There are 60 minutes in an hour so 15/60 is 0.25.
Thus, adding that to the 30 hours gives us 30.25.
If she makes $15.60 per hour we just multiply that by 30.25 hours and get the answer.
[tex]\frac{15.60}{hour}*30.25 hours = 471.9\\[/tex]
The [tex]\frac{}{hour}[/tex] comes from the wording of per hour, and since the unit is in the denominator, when we multiply it by the 30.25 hours, the units cancel out. Thus all we are left with is the amount of dollars made, which is $471.90.
Austin and his wife go out to dinner. Their bill is $59.36. They want to leave a 19%
tip, and there is a sales tax of 5.5%. What is the final amount they will pay?
$62.62
$73.90
$74.49
$70.64
Answer:
The final amount they will pay is $74.49
Step-by-step explanation:
59.36(Check)*0.19(19% tip rate)=11.27
59.36+11.27=70.62 Check+Tip
70.62(Check total)*0.055(5.5% tax)=3.87
70.62+3.87=74.49 Total check, tip & tax
You deposit $200 in a savings
account that pays a simple
interest rate of 3.25% per year.
How much interest will you earn
after 5 years?
Answer:
$16.25
Step-by-step explanation:
First, you have to find 3.25*5 which is 16.25.
16.25 is the percent rate of your total interest over the course of 5 years.
In other words, you have to do 200*0.1625 which is 32.5.
So, your answer is $16.25.
Good luck!

Answer:
w= 8/7
Step-by-step explanation:
1. divide the numbers
[tex]12w-1*10=6-2w[/tex]
2. multiply the numbers
[tex]12-10=6-2w[/tex]
3. rearrange terms
[tex]12-10=-2w+6[/tex]
4. add 10 to both sides of the equation
[tex]12w-10+1-=-2w+6+10[/tex]
5. simplify
[tex]12w=-2w+16[/tex]
6. add 2w to both sides of the equation
[tex]12w+2w=-2w+16+2w[/tex]
7. simplify
[tex]14w=16[/tex]
8.divide both sides of the equation by the same term
14w/14 = 16/14
9. simplify
w = 8/7
Answer:
[tex]w = 2[/tex]
Step-by-step explanation:
[tex] \frac{(12w - 20)}{2} = 6 - 2w[/tex]
[tex]6w + \frac{ - 20}{2} = 6 - 2w[/tex]
[tex]6w + \frac{( - 10.2)}{(1.2)} = 6 - 2w[/tex]
[tex]6w + 10 = 6 - 2w[/tex]
[tex]6w - 10 + 2w = 6 - 2w + 2w[/tex]
[tex]6w + 2w - 10 = 6 - 2w + 2w[/tex]
[tex]8w - 10 = 6 - 2w + 2w[/tex]
[tex]8w - 10 = - 2w + 2w + 6[/tex]
[tex]8w - 10 = 6[/tex]
[tex]8w - 10 + 10 = 6 + 10[/tex]
[tex]8w = 6 + 10[/tex]
[tex]8w = 16[/tex]
[tex] \frac{8w}{8} = \frac{16}{8} [/tex]
[tex]w = \frac{16}{8} [/tex]
[tex]w = \frac{2.8}{1.8} [/tex]
[tex]w = 2[/tex]

Ajar contains 3 red and 5 green balls identical in all aspects except color. If two balls are drawn at random, then the probability that the two balls drawn are not green is
Answer:
3/28.
Step-by-step explanation:
Total of 8 balls in the jar.
Prob (first one not green (= that its red) = 3/8
Prob ( Second one is also red) = 2/7.
So probability that both are not green = 3/8 * 2/7
= 6/56
= 3/28.
The center of the circle whose equation is (x + 2)² + (y - 3)² = 25 is
Answer:
The center of the circle is at: C=(−2,3).
The radius of the circle is r=5.
Step-by-step explanation:
A circle with center at (h,k) and a radius of r has equation (x−h)2+(y−k)2=r2.
In this example our circle equation can be written as:
(x−(−2))2+(y−3)2=(5)2
So, we have: h=−2 , k=3 and r=5.

Consider the following two loans for P=$12,000.
Loan A: 5 year loan, annual interest rate of 5%.
Loan B: 3 year loan, annual interest rate of 8%.
Answer:
Simple interest-?
Step-by-step explanation:
P= 12000
T=5yrs
R=5%
Now,
Simple interest - PTR/100
= 12000*5*5/100
= $3000
Again,
P=12000
T=3yrs
R=8%
Now,
Simple interest - PTR/100
= 12000*3*8/100
= $2880

1) Eight times the difference between a number and seven, is the same as when five times
the number is increased by four. Find the number.
Tip: Go step-by-step
Let the number = x
Eight times the difference between a number and seven.. = 8(x-7)
is the same as... =
the number increased by 4.. x+4
8(x-7)=x+4
Distribute
8x-56=x+4
Subtract x from both sides
7x-56=4
Add 56 to both sides
7x=60
x=60/7
