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.
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.

Answer:
A.) 15984.42cm^2/5088πcm^3
B.) 3466.56cm^2/1104πcm^2
Step-by-step explanation:
A.) fine the V of the cone and then cylinder then add them.
B.) The cone you have to find the LA (lateral area) to do that you would do is find S (slant) so you would do 12^2+16^2 which is 400 then u have to find the square root of it which is 20 which is that slant of the cone. After that you would do 12x20 which gives 240 that would be the LA of the cone.
Then you would find the LA of the cylinder which you have to do is 30x12 which is 360 then multiply it by 2 which gives 720.
Lastly you find the area of the base which in this case is a circle and that would be 144 add all of them then get the SA

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

Rachel enjoys exercising outdoors. Today she walked 5 2/3 miles in 2 2/3 hours. What is Rachel’s unit walking rate in miles per hour and in hours per mile?
Answer:
5 2/3 divided by 2 2/3 = 17/3 divided by 8/3 = 17/8 = 2 1/8 miles per hour
2 2/3 divided by 5 2/3 = 8/3 divided by 17/3 = 8/17 hours per mile

D
Step-by-step explanation:
because it's normal reasonal if it is wrong i will look for a better answer
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.

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.
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?
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)
Six less than two times a number is no more than 17.
