To create a cumulative response record, we need to add up the number of responses at each time point with the number of responses at all previous time points.
Starting with the first time point:
At time 0 seconds, there were 0 responses.
At time 10 seconds, there were 0 + 1 = 1 responses.
At time 20 seconds, there were 0 + 1 + 2 = 3 responses.
At time 30 seconds, there were 0 + 1 + 2 + 1 = 4 responses.
At time 40 seconds, there were 0 + 1 + 2 + 1 + 3 = 7 responses.
At time 50 seconds, there were 0 + 1 + 2 + 1 + 3 + 4 = 11 responses.
At time 60 seconds, there were 0 + 1 + 2 + 1 + 3 + 4 + 6 = 17 responses.
At time 70 seconds, there were 0 + 1 + 2 + 1 + 3 + 4 + 6 + 9 = 26 responses.
At time 80 seconds, there were 0 + 1 + 2 + 1 + 3 + 4 + 6 + 9 + 10 = 36 responses.
At time 90 seconds, there were 0 + 1 + 2 + 1 + 3 + 4 + 6 + 9 + 10 + 7 = 43 responses.
At time 100 seconds, there were 0 + 1 + 2 + 1 + 3 + 4 + 6 + 9 + 10 + 7 + 9 = 52 responses.
At time 110 seconds, there were 0 + 1 + 2 + 1 + 3 + 4 + 6 + 9 + 10 + 7 + 9 + 8 = 60 responses.
At time 120 seconds, there were 0 + 1 + 2 + 1 + 3 + 4 + 6 + 9 + 10 + 7 + 9 + 8 + 9 = 69 responses.
Plotting these cumulative response values against time gives the cumulative response record:

Answer:
y = - 2x + 1
Step-by-step explanation:
Substitute an x value from the table into the equation
x = 1 : y = - 2(1) = - 2 ← require to add 1 to obtain y = - 1
x = 4 : y = - 2(4) = - 8 ← require to add 1 yo obtain y = - 7
Then equation describing the relationship is
y = - 2x + 1
does this table represent a liner or nonlinear function
Answer:Nonlinear
Step-by-step explanation:
The ratio is 1:8 meaning if you divide the second part by 8 it should get you the first part but 16/8 is 2 not 3 therefore it is not linear
Lara made some chocolate tarts for every 5 cups of chocolate chips she added 3 cups of sugar.What is the ratio of chocolate chips into the sugar?
Answer:chocolate chips : Sugar
5 : 3
Step-by-step explanation:
A ratio tells us the relationship between 2 or more items, explaining how many times the value of one item is contained in another and denoted as either a/b, a to b or a:b.
Here, Lara made chocolate tarts , For every 5 cups of chocolate chip, 3 cups of sugar are added, Therefore the ratio of chocolate chips to sugar is expressed as
chocolate chips : Sugar
5 : 3

Answer:
Sean is incorrect.
Step-by-step explanation:
The interior angle of this triangle with the exterior angle of 80° is 100°, so the sum of the remaining angles should be 80°, which means (X + 5) + (X - 5) = 80. Take off the parenthesis, 2X = 80, which means X = 40°. This is where Sean's answer was wrong, he forgot that the remaining angles are X + 5 and X - 5 instead of X, which means that the angles in this triangle should actually be 100°, 45°, and 35°.

f(x)=x-4 is the answer i believe
Answer :
The function is
Step-by-step explanation:
Given values in table :
x f(x)
3 -1
4 0
5 1
6 2
Here we see there is a difference of 4 in the values of x and f(x)
i.e. 3-(-1)=4
or 4-0=4
Similarly 5-1=4
6-2=4
So x-F(x)=4
Adding F(x) -4 both sides
x-F(x) +F(x) -4=4+F(x) -4
We have F(x)= x-4

A bakery made 1, 575 butter cookies. After arranging the cookies into packages, the bakery did not have any cookies left. How many cookies could have in each package? *
1 point
A. 6
B. 5
C. 9
D.4
Answer:
B. 5 might be the answer.
Answer: Either B. 5 or C. 9
Explanation: Assuming there would be the same amount of cookies in each package, to see if they would all fit perfectly and there be no leftover cookies, simply divide 1,575 (the number of total cookies) by how many cookies could be in each package. If it comes out with "point something," then the numbers after the decimal point would be how many cookies will be leftover. 5 and 9 both end up with no decimal, so that's as much as I know.

Answer:
Graphite is a form of carbon.
Step-by-step explanation:
Pencils are usually made from graphite and clay.
Now, graphite is a from of carbon and as such it is soft due to the weak intermolecular forces it possesses in between it's layers. Therefore if the graphite is increased, this will make the pencil not to be hard enough when writing and easily slide.

what’s the slope_____
Answer:
-4
Step-by-step explanation:
The formula for finding the slope of a line is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. We can take any two points given to us from the table and plug them into that expression. For example, we can use the points (0,0) and (2,-8).
[tex]\frac{y_2-y_1}{x_2-x_1}\\= \frac{-8-0}{2-0}\\= \frac{-8}{2}[/tex]
Simplify the fraction
[tex]= -4[/tex]
Therefore, the slope of the line is equal to -4.

Laura deposited $12,000 into an account that earns 8% interest. How much money will
she have in 5 years if the interest is compounded quarterly?
9514 1404 393
Answer:
$17,831.37
Step-by-step explanation:
The compound interest formula is useful.
A = P(1 +r/n)^(nt)
A = $12,000(1 + .08/4)^(4·5) = $12,000(1.02^20)
A = $17,831.37
Laura will have $17,831.37 in 5 years.
