The cumulative frequency distribution is a type of statistical representation that shows the total number of data points in a sample that are less than or equal to a given value. It is often used to understand the distribution of data within a sample and to identify patterns or trends.
To construct a cumulative frequency distribution for given data, follow these steps:
Sort the data in numerical order from lowest to highest.Determine the number of data points in the sample. This is the total frequency for the distribution.Calculate the cumulative frequency for each data point by adding the frequency of that point to the cumulative frequencies of all previous points.Create a table or graph with the data points as the x-axis and the cumulative frequencies as the y-axis.For example, given the following data:
[tex]10, 15, 20, 25, 30, 35, 40, 45[/tex]The cumulative frequency distribution would be:
Data Point | Frequency | Cumulative Frequency
10 | 1 | 1
15 | 1 | 2
20 | 1 | 3
25 | 1 | 4
30 | 1 | 5
35 | 1 | 6
40 | 1 | 7
45 | 1 | 8
This distribution could be represented in a graph by plotting the data points on the x-axis and the cumulative frequencies on the y-axis and connecting the points with a line.
The answer is general since the data is not provided.

What is the slope of the line RS that contains the points R(-2, -3), S(3, -5)
HELP ASAP
Answer:
[tex]slope = \dfrac{-2}{5}[/tex]
Step-by-step explanation:
The slope of a line passing through points , [tex] (x_1,y_1) [/tex] and [tex] (x_2,y_2) [/tex] is ,
[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
Using this we have ,[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\implies slope = \dfrac{-5+3}{3+2}\\\\\implies \boxed{\boxed{slope = \dfrac{-2}{5}}}[/tex]

For the equation y= 8 • 2x complete the table and plot the ordered pairs on the
graph.
Answer:
y=16x
Step-by-step explanation:
y=(8)(2)x
--HEART IF THIS HELPED OR BRAIN ME!!--
The ordered pairs (-3, 1), (-2, 2), (-1, 4), (0, 8), (1, 16), (2, 32) and (3, 64) on the graph are plotted below.
What is the exponential function?Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
The given equation is y=8×2ˣ.
Here, in table
x -3 -2 -1 0 1 2 3
y 1 2 4 8 16 32 64
So, the ordered pairs are (-3, 1), (-2, 2), (-1, 4), (0, 8), (1, 16), (2, 32) and (3, 64)
Exponential functions have a horizontal asymptote. The equation of the horizontal asymptote is y=0.
Horizontal Asymptote: y=0
Therefore, the ordered pairs on the graph are plotted below.

A number cube is rolled what is the likelihood that a number less than or equal to three is rolled
Unlikely
Equally likely
Likely
Certain
Answer:
equally likely
Step-by-step explanation:
there are 3 numbers less than or equal to 3. divide that by every number on the cube. Then you get 0.5.
move the decimal twice and turn it into a percent 50%
50% is equally likely.

The fractuon 3/5 is found between which pair of fractions on a number line?
Answer: It's kinda simple, 2/5 and 4/5
Just add 1 to the numerator of the original fraction, and there's where you get 4/5. Then subtract 1 from the original fraction, and that's where you get 2/5!

A line has a slope of 0 and passes through the point (-4, 3). What is its equation in slope-intercept form.
Answer:
y = 3
Step-by-step explanation:
We already know the slope, all we need to do is find the y-intercept.
You have to plug the coordinates into the equation, y = 0x + b
y = 0x + b
3 = 0(-4) +b
3 = 0 + b
3 = b
The equation is y = 3

Jamie is twice as old as Natalie now. Give years ago the sum of their ages was 26. How old is each person now?
answer:
8. 67 and 17. 36
step-by-step explanation:
hi there!
to find out the age of both girls, i believe that we should divide the number 26 by 3 because jamie is twice as old as natalie meaning ( natalie ) is younger
26/3
= 8. 67
meaning 8.67 is how old natalie is/was
add 8.68 to itself once and you will get jamie's age!
8. 67 + 8. 67
= 17. 34
meaning 17. 34 is how old jamie is/was
sorry if i misread the question or made it a little confusing! but i do hope that this ends up helping you! :)
