what is the mean of this data set 8,2,5,12
Answer:
6.75
Step-by-step explanation:
Add up all the numbers in the data set :
8 + 2 + 5 + 12 = 27
Divide 27 by the total numbers in the data set :
27 ÷ 4 = 6.75
Therefore, the mean if the data set is 6.75

A survey is being conducted to decide on how much time people spend watching sports on television. Tell whether the given sample is biased or unbiased. Explain your answers. (NOT A MULTIPLE CHOICE)
1. Every fifth person who enters Little Casesars Arena for a Red Wings game
2. Every tenth name in the phone.
Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others. From this definition,
For sample 1, Every fifth person who enters Little Casesars Arena for a Red Wings game. This is not biased because no person is more likely to be selected than another
For sample 2, Every tenth name in the phone. This is also not biased
because no person is more likely to be selected than another

The length of a rectangular garden is 12 ft longer than the width, w. If the garden has a perimeter of 76 ft. Determine the length and width of the garden.
Step-by-step explanation:
length = l
width = w
perimeter of garden = 76 ft
perimeter = 2l + 2w
2l + 2w = 76 (eqn 1)
l - w = 12 (eqn 2)
(eqn 1) ÷ 2
l + w = 38 (eqn 3)
(eqn 2) + (eqn 3)
2l = 50
2l/2 = 50/2
l = 25
The length of the garden is 25 ft.
Substitute l = 25 into (eqn 3)
l + w = 38
25 + w = 38
w = 38 - 25
w = 13
The width of the garden is 13 ft.

What is the area of a sector bounded by an 80° arc? (use 3.14 for 1)
16.75 ft
Answer:
Area of sector bounded by angle = 100.37 ft² (Approx.)
Step-by-step explanation:
Given:
Radius of a circle = 12 feet
Arc angle θ = 80°
Find:
Area of sector bounded by angle
Computation:
Area of sector bounded by angle = [θ/360][πr²]
Area of sector bounded by angle = [80/360][(3.14)(12)²]
Area of sector bounded by angle =[0.22][(3.14)(144)]
Area of sector bounded by angle = [0.22][452.16]
Area of sector bounded by angle = 100.37 ft² (Approx.)

A SPINNER IS DIVIDED INTO EQUAL BLACK, WHITE, RED. YELLOW, AND GREEN
SECTIONS. IF I SPIN THE SPINNER 95 TIMES ABOUT HOW MANY TIMES WOULD IT LAND ON YELLOW
Answer:
We would expect to get yellow 19 times.
Step-by-step explanation:
The probability of getting yellow is 1/5 (It is one out of five options)
To find how many times it is probable to get yellow, multiply this probability by the number of trys: (1/5)(95)=19
help lol i can’t do math and everything is due at midnight
Solve x + 19 = 47.
Select one:
x = 893
x = 66
x = 28
x = 18
the answer is 28 hoped that helped
Answer:
x=28 (B)
Step-by-step explanation:
x = 28 (B)
You need to subtract 19 from both sides to get 28.
Pls help because I’m not sure

Answer:
11.3
Step-by-step explanation:
Set up your equation:
a² + b² = c²
Plug in your values:
a² + 4² = 12²
Get a² by itself:
a² = 12² - 4²
Square your numbers and subtract:
a² = 144 - 16
a² = 128
Find the square root of both sides:
√a² = √128
a = 11.3

What is the slope of the line that passes through the points (3, 2) and (−1,2)? Write your answer in the simplest form
Answer:
slope = 0
Step-by-step explanation:
To find the slope of a line that passes between a pair of points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the points (3,2) and (-1,2) into the formula and simplify:
[tex]m = \frac{(2)-(2)}{(-1)-(3)} \\m = \frac{2-2}{1-3} \\m = \frac{0}{-2} \\m=0[/tex]
So, the slope is 0.
