I fill an aquarium to a depth of 3/8 meters in 6 minutes. What is the unit rate in minutes per meter?
Answer:
16 minutes per meter
Step-by-step explanation:
Depth = 3/8 meters
Time taken = 6 minutes
What is the unit rate in minutes per meter?
Time taken per depth = minutes per meter
Unit rate in minutes per meter = 6 minutes ÷ 3/8 meters
= 6 minutes × 8/3 meters
= 48/3
= 16 minutes per meter

Combine like terms
1) -2(x+6)
2) 10-4(6-x) + 5x
Answer:
1) -2x-12
2) 9x-14
Step-by-step explanation:
1). We use distributive property. We have to multiply -2 by x and 6. This means that the expression is -2x-12.
2). We use the distributive property again. We have to multiply -4 by 6 and x. Therefore, the equation will be 10-24+4x+5x. Then, we have to combine like terms. 10-24 is equal to -14 and 4x+5x is equal to 9x. Therefore, it is equal to 9x-14.

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.
Add t to 2 then add 4 to the result
Answer:
1. 2+t= 2t
2. 2t+4= 2t+4
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.

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

Paula has her own business making cakes for
special occasions. The total price (p) of one
of Paula’s cakes is represented by the equation
p=0.75s +10 , where s is the number of
people the cake serves. What does the .75
represent in this situation and what does the 10 represent in this equation?
Answer:
Since Paula has her own business of making cakes for special occasions, and the total price (P) of one of Paula's cakes is represented by the equation P = 0.75S +10, where S is the number of people the cake serves, for determine what does the 0.75 represent in this situation and what does the 10 represent in this equation, the following mathematical reasoning must be carried out:
P is the price of the cake
S is the number of servings
Therefore, 0.75 is the value of each serving, which can be variable (the number of servings can vary)
In turn, 10 is the fixed cost of each cake.

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
