Suppose that a committee is studying whether or not there is a waste of time in our judicial system. It is interested o the mean amount of time individuals waste at the courthouse waiting to be called for jury duty. The committee randomly surveyed 81 people who recently served as jurors. The sample mean wait time was 8 hours with a sample standard deviation of 4 hours.
i. ¯x=
ii. sx=
iii. n=
iv. n−1=
Answer:
i. ¯x= 8
ii. sx= 4
iii. n= 81
iv. n−1= 80
Step-by-step explanation:
i. ¯x=
This is the sample mean, which is 8 hours.
ii. sx=
Standard deviation of the sample, which is of 4 hours.
iii. n=
Size of the sample, which is 81.
iv. n−1=
Degrees of freedom(sample size subtracted by 1), which is 81 - 1 = 80

to spend to much traveling and country the day she arrived the exchange rate was 1.4 country a dollars Per country B dollars if she exchange 500 country B dollars when she arrived how many country eight dollars she receive
Answer:
She receives 700 country A dollars.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
1.4 country a dollars Per country B dollar
She exchanges 500 country B dollars, so:
1.4 country A dollars - 1 country B dollar
x country A dollars - 500 country B dollars
Applying cross multiplication:
[tex]x = 1.4*500 = 700[/tex]
She receives 700 country A dollars.
Divide. Write your answer in the following form:

solve the following equation 1÷x=2
Answer:
Your answer would be x = 1/2
Step-by-step explanation:
1/x = 2
You would divide x on both sides...then they would cancel each other out.
But now you're left with...
1 = x•2
So, re-order the terms so constants are on the left
1 = 2x
Divide 2 on both sides...
Now you're left with
1/2=x or more practically it would be x = 1/2

Geometry: Find the area of each figure. Round to the nearest tenth.
Answer/Step-by-step explanation:
Apply the formula for area of a triangle with an included angle and two given side lengths, A = ½*a*b*Sin(θ)
15. a = 3 cm,
b = 3 cm,
θ = 140°
A = ½*3*3*Sin(140)
A = 2.89 ≈ 2.9 cm² (nearest tenth)
16. a = 5 yd,
b = 8 yd,
θ = 98°
A = ½*5*8*Sin(98)
A = 19.81 ≈ 19.8 yd² (nearest tenth)
17. a = 5 cm,
b = 6 cm,
θ = 152°
A = ½*5*6*Sin(152)
A = 7.04 ≈ 7.0 cm² (nearest tenth)
17. a = 5 m,
b = 6 m,
θ = 150°
A = ½*5*6*Sin(150)
A = 7.5 ≈ 7.5 m² (nearest tenth)

Joseph is going on a trip and he needs to rent a car. He looks online and finds two companies that offer different pricing options for car rentals. Company A charges $0.25 per mile plus a $50 rental fee. Company B charges $0.45 per mile plus a $20 rental fee.
What is the maximum number of miles that Joseph can drive in order for Company B to be a better buy? The company charges only for whole number mileage (not fractional increments of miles driven).
A) 125 miles
B) 149 miles
C) 150 miles
D) 151 miles
Answer:
E.The price for travelling 150 miles is same for both company.
Step-by-step explanation:
We are given that Joseph is going on a trip and he needs to rent a car.
Company A
Charge $0.25 per mile plus $50 rental fee.
Company B charges 40.45 per mile plus $20 rental fee.
A.Total distance=150 miles
Company A
Charges for 150 miles=$37.5
Total charges=37.5+50=$87.5
Company B
Charges for 150 miles==$67.5
Total charge=20+67.5=$87.5
The price for travelling 150 miles is same for both company.
But if distance greater than 150 miles such 155 miles
Company A
Total charge=$88.75
Company B
Total charges=$89.75
Company A is better deal if Joseph more than 150 miles.
If distance 145 miles
Price form company A=$86.25
Price form company B=$85.25
Company B is better deal if Joseph travel less than 150 miles.
Hence, option E is true.
I hope this helps you <3333
Jessie is building a cabinet door, which is pictured below. The center of the cabinet door is 12 inches by 16 inches, and the border of the cabinet door has a width of x inches. The entire cabinet door has an area of exactly 396 square inches.
Clockwise from the top, the picture reads, x, 12 inches, 16 inches, x, Figure not drawn to scale.
Write an equation in standard form that can be used to find x , the width of the border.
Measuring to fit a cabinet opening includes a few extra steps to get the doors made in the right sizes for your remodel or renovation:
Measure the inside edges: When measuring the width, measure from left to right, starting with the inside edge of the left stile (vertical part of the face frame) to the inside edge of the right stile. When measuring height, measure from the inside edge of the bottom rail (horizontal part of the face frame) to the inside edge of the top rail. We build to 1/16 inch increments, so be precise.
Add space for door overlay: Cabinet doors for framed cabinets must be larger than the cabinet opening to look right and close properly. We refer to this as an "overlay". The industry standard for most cabinet doors is a 1/2 inch overlay around the cabinet door. To create a 1/2 inch door overlay on all four sides, add 1 inch to your total height, and 1 inch to your total width

A.3x2 + 4 = 52
B.x2 - 121 = 0
C.(b + 4)2 = 49
Answer:
A. 3x^2 + 4 = 52
3x^2 = 52 - 4
3x^2 = 48
x^2 = 48/3
x^2 = 16
x = [tex]\sqrt{16}[/tex]
x = 4
B. x^2 - 121 = 0
x^2 = 121
x = [tex]\sqrt{121}[/tex]
x = 11
C. (b + 4 )2 = 49
2b + 8 = 49
