HURRY! What value of m completed the two-way table?
Answers
=========================================================
Explanation:
We're told that there are 50 people in each grade that are surveyed. So that means 50 eighth graders were surveyed.
Add up the values along the bottom row. Set the sum equal to 50 and solve for m
m+8+29 = 50
m+37 = 50
m = 50-37
m = 13
Then note how 13+8+29 = 50 along the bottom row. Also, for the top row we have 17+15+18 = 50 as well.
Answer:
A - 13
Step-by-step explanation:
50 (8th graders) - 8 (tiling lovers) - 29 (carpeting lovers) = 13 (wooden floor lovers)

Use the function b = 14j + 12 to find the value of b when j = 3.
Answers
Answer:
b=54
Step-by-step explanation:
b=14(3)+12
b=42+12
b=54
Hey there!
b = 14j + 12
TURN the EQUATION
14j + 12 = b
j = 3
NEW EQUATION: 14(3) + 12
14(3) + 12
14(3) = 42
42 + 12 = b
SIMPLIFY ABOVE and you will have your answer of b
42 + 12 = 54
Therefore your answer is: b = 54

A game at the fair involves a wheel with seven sectors. Two of the sectors are red, two of the sectors are purple, two of the sectors are yellow, and one sector is blue.
Landing on the blue sector will give 3 points, landing on a yellow sector will give 1 point, landing on a purple sector will give 0 points, and landing on a red sector will give –1 point.
Let X = the points you have after one spin. Fill out the missing values in the table.
If you take one spin, what is your expected value?
What changes could you make to values assigned to outcomes to make the game fair? Prove that the game would be fair using expected values.
Answers
The expected value based on the probability will be 3/7.
How to calculate the probability?
Landing on the blue sector will give 3 points = 3/7 points
Landing on a yellow sector will give 1 point = 2/7 points
Landing on a purple sector will give 0 points = 0 points
Landing on a red sector will give –1 point. = -2/7 points
The expected value will be:
= 3/7 + 2/7 + 0 - 2/7
= 3/7
The change to the values assigned to outcomes to make the game fair is to make 3.5 points for landing on the blue sector.

c.) 31
Step-by-step explanation:
comment if u need explanation :))
Answer:
3 x 3 x 3 = 27
2 x 2 = 4
27 + 4 = 31, the answer is C
Since it is exponents
3 to the power of three means you multiply three by itself 3 times which equals 27.
Same with 2 to the power of 2,
you multiply 2 by itself 2 times therefore you get 4 and add them up to get 31.

Answers
Answer:
184 cm^2
Step-by-step explanation:
To find the surface area, find the area of each of the faces and add them up.
Let's start with the base/bottom.
The dimensions are 6 and 10, and it is a rectangle.
Area = 6 x 10 = 60 cm^2
Next, lets do the slanted sides.
The dimensions are 10 and 5, and they are both rectangles.
Area = 10 x 5 = 50 cm^2
Since there are 2 of the slanted sides, multiply 50 by 2.
50 x 2 = 100 cm^2
Then, do the triangles.
The dimensions are 6 (base) and 4 (height)
Area = 6 x 4 / 2
Area = 24 / 2
Since there are 2 triangles, we do not need to divide by 2. We will need to multiply by 2 afterwards, so there's no point in dividing by 2.
24 cm^2
Finally, add up all the areas.
60 + 100 + 24 = 184 cm^2
Heh, funny, there's no answer choice for that... maybe ask your teacher?
