Answer:

A. select all students who are currently in the chess club

Step-by-step explanation:

If the teacher randomly selects students, there is a greater chance that many don't play chess. But, if the teacher selects all the students who are currently in the chess club, most likely all of them play chess because they are in the chess club.

The scatter plot below represents the weight of a box of cookies based on the number of cookies in the box. A best-fit line shows the relationship.

Answers

Answer:

a. true

b. false

c. false

d. false

e. true

Step-by-step explanation:

a is true because the graph is measuring the weight of the box based on the number of cookies in it, and the box has weight even without cookies in it.

b is false because the slope of the line is 1/2, and each cookie weighs 1/4 oz.

c is false because there is an association between the number of cookies and the weight of the box.

d is false because that is the weight of one cookie, and doesn't take into account the weight of the box by itself.

e is true because the graph shows that at 13 cookies, the box weighs around 3.75 ounces.

To find the volume of a rectangular prism you multiply the 3 dimensions, length x width x height. What combination of numbers will give me a volume of 17?

Answers

1, 1 and 17. Since 17 is a prime number, there isn’t exactly numbers that are multiplied by each other that give 17.

Answer:

1, 1, 17

Step-by-step explanation:

17 is a prime number. This means the only factors are 1, and 17. This means that since only 17, and 1 multiply to 17, to get a volume of 17 you can only use 1, and 17 (1, 1, and 17)

Step-by-step explanation:

I'm not sure, but if you divide the number of people by each candidate, you'll get a value that the number of candidates will equal the number of people. I repeat I'm not sure of my answer.

All of the choices are correct
622,620 ÷ 3 = 207,540
622,620 ÷ 9 = 69,180
622,620 ÷ 4 = 155,655
622,620 ÷ 10 = 62,262

6-(2x)=17 because less than means minus. So 6- two times a number. We don’t know what number so we use X as a variable to fill in for that number. We have to solve multiplication first because PEMDAS so we put the 2X in parentheses so it’s solved before we subtract 6! Then we put =17 because it says it is no more than 17, meaning it’s equal to 17!

Answers

Answer:

11126

Step-by-step explanation:

The mean of a set of data is another name for its average. It is the sum of the data, divided by the number of numbers in the sum.

If you use a calculator to help you with the computation of the addition or division, you may as well use the calculator's "mean" function to do the job.

The mean of the given 6 values is their sum, divided by 6. The units of the mean are the same as those of the contributors.

(1117 +1409 +675 +536 +1398 +1621)/6 = 6756/6 = 1126 . . . . degrees F

The mean of the data is 1126 °F.

1,126 Fahrenheit. next time when you see the word “mean” add all the numbers together the divide by how many number there are. so in this case you add them all together the divide by six because there is six numbers.

(Will l give 25 points!) Solve the system of linear equations by substitution. -8x + y = 5 and 5x - y = 3

Answers

Answer:

x = -8/3 and y = -49/3

Step-by-step explanation:

(Step 1) To solve using substitution, you first need to isolate a variable in one of these equations. I chose to isolate "y" in the following equation.

-8x + y = 5 <--- Original equation

y = 5 + 8x <--- Add 8x to both sides

(Step 2) Now, substitute (5 + 8x) for "y" in the second equation.

5x - y = 3 <--- Original equation

5x - (5 + 8x) = 3 <--- Substitute 5 + 8x for "y"

5x - 5 - 8x = 3 <--- Distribute (-) in the parentheses

-3x - 5 = 3 <--- Combine terms with "x"

-3x = 8 <--- Add 5 to both sides

x = -8/3 <--- Divide both sides by -3

(Step 3) Since you know the value of "x", plug it into one of the equations to solve for "y".

y = 5 + 8x <--- Original (rearranged) equation

y = 5 + 8(-8/3) <--- Plug (-8/3) for "x"

y = 5 - 64/3 <--- Multiply

y = 15/3 - 64/3 <--- Convert 5 into a fraction

y = -49/3 <--- Subtract

(Step 3.5) You can check your work by plugging "y" into the other equation to see if the answer for "x" is the same.

5x - y = 3 <--- Original equation

5(-8/3) - y = 3 <--- Plug (-8/3) for "x"

-40/3 - y = 3 <--- Multiply

-40/3 - y = 9/3 <--- Convert 3 into a fraction

-49/3 - y = 0 <--- Subtract both sides by 9/3

-49/3 = y <--- Add both sides by "y"

The value of the system of equations is x = -8/3 and y = -49/3.

Using the quadratic equation, number out the 2 equations and find out x or y first in my solution, i find x first and than substitute x=4 into equation 2 to find y.

You can either substitute the y in the first equation and make it -4x+x+2, or you could make the first equation equal to 4x-10 (y=4x-10, move the -4x) then you could solve, and since you have two values of y so they’re both the same. This is how it would look like:
