3. How many different ways can the letters in the word grade be arranged?
Answer:
Six letters---6
Step-by-step explanation:
You Welcome G!
The solution is, the letters in the word GRADE can be arranged in 120 ways.
What is combination?In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.
here, we have,
Given that we are to evaluate the number of ways to arrange the letters in the word GRADE,
In the word GRADE, we have 5 distinct letters:
G(1), R(2), A(3), D(4), E(5).
There are 5 letters.
Thus, the number of ways of arranging the letters is evaluated as
5! = 1×2×3×4×5
=120
Hence, the letters in the word GRADE can be arranged in 120 ways.

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?

D. 13
Answer:
Hello!
answer: 13
Step-by-step explanation:
The mode is simply just the number that is shown the most in the data set so as you can see 13 is shown the most so 13 is our mode Hope that helps!

Answer:
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.
Landon earns 10% commission on his total sales. What must be his total sales in oder to earn a commission of $ 145?
Answer: [tex]\$1450[/tex]
Step-by-step explanation:
Given
Landon earns a 10% commission on his total sales
Suppose his total sales is x to get a commission of $145 i.e.
[tex]\Rightarrow x\times 10\%=145\\\Rightarrow 0.1x=145\\\Rightarrow x=\$1450[/tex]
Therefore, the amount of total sales must be $1450

HURRY! What value of m completed the two-way table?
=========================================================
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)

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.
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.

Answer:
A. 30,000 square inches
Step-by-step explanation:
multiply the dimensions by 80

2 1/2 x 80 = 200
find the area
200 x 150 = 30000 [tex]in^2[/tex]
Answer:
A or C or b
Step-by-step explanation:
1 7/8+1 7/8= 2 14/8

1 14/8 + 5= 6 14/8
[14/8 = 14÷8=

14-8=6]

4. A drawer contains 21 black socks and 9 white socks. A number generator simulates randomly selecting 10 socks from the drawer. The number generator is used 10 times and the number of black socks in each trial is shown in the plot.
Does this number generator appear to be fair?
WHY OR WHY NOT?
I know the answer is yes it appears to be fair, but please answer WHY. Thank you :)
There are 21 black socks and 9 white socks. Theoretically, the probability of picking a black sock is 21/(21+9) = 21/30 = 0.70 = 70%
Assuming we select any given sock, and then put it back (or replace it with an identical copy), then we should expect about 0.70*10 = 7 black socks out of the 10 we pick from the drawer. If no replacement is made, then the expected sock count will likely be different.
The dot plot shows the data set is
{5, 5, 6, 6, 7, 7, 7, 8, 8, 8}
The middle-most value is between the first two '7's, so the median is (7+7)/2 = 14/2 = 7. This can be thought of as the average expected number of black socks to get based on this simulation. So that's why I consider it a fair number generator because it matches fairly closely with the theoretical expected number of black socks we should get. Again, this is all based on us replacing each sock after a selection is made.

Use the function b = 14j + 12 to find the value of b when j = 3.
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
