Answer:
A frequency table shows the distribution of observations based on the options in a variable. Frequency tables are helpful to understand which options occur more or less often in the dataset. This is helpful for getting a better understanding of each variable and deciding if variables need to be recoded or not.
Step-by-step explanation:
hope this helps! :)
The usage of frequency table is to create graphs such as histograms, bar charts, and pie charts to visualize the data.
We are given that;
The frequency table
Now,
A frequency table is a table that lists items and shows the number of times the items occur. It is a way of organizing data and summarizing how often each value or category appears in a dataset.
Frequency tables can be used for any type of variable, such as categorical, ordinal, or numerical.
Frequency tables can help us to understand the distribution of data, identify patterns, and compare different groups.
For example, suppose we have a dataset of 20 students' favorite colors. We can make a frequency table to show how many students prefer each color:
| Color | Frequency |
| ----- | --------- |
| Red | 5 |
| Blue | 7 |
| Green | 4 |
| Yellow| 2 |
| Pink | 2 |
Therefore, by the table answer will be to create graphs such as histograms, bar charts, and pie charts to visualize the data.

What is the value of x in the solution to this system of equations? y + 2x = -1 y = 3x+4?
Answer:
x = -1
Step-by-step explanation:
y + 2x = -1
Subtract 2x from both sides;
y = -2x - 1
y = 3x + 4
-2x - 1 = 3x + 4
Subtract 3x from both sides;
-5x - 1 = 4
Add 1 to both sides;
-5x = 5
Divide both sides by -5
x = -1

Step-by-step explanation:
oh yuh
No, the measurements in the table given are not showing equivalent proportional relationships.
What are proportional relationships?Proportional relationships are relationships between two variables where their ratios are equivalent.
Given is a table showing, Proportional relationships for four serving of pineapple-mango juice,
Pineapple juice Mango juice
2 [tex]1\frac{1}{9}[/tex]
[tex]2\frac{1}{2}[/tex] 4

Checking for proportional relationships;
1) Pineapple juice / Mango juice = 2 ÷ 10/9 = 9 / 5
2) Pineapple juice / Mango juice = 5 / 2 ÷ 4 = 5 /8
3) Pineapple juice / Mango juice = 3 ÷ 9/2 = 2 / 3
As we see, that all three proportions are not equal.

What is the length of the line?
Using the Pythagorean theorem, the length of the line is: √45 = 6.7 units.
How to Find the Length of a Line Using Pythagorean Theorem?The Pythagorean theorem is the equation that describes how the lengths of the three sides of a right triangle relate to each other. If a and b are smaller legs, and c us the hypotenuse of the triangle, the Pythagorean theorem states that:
c² = a² + b².
Consider the line above to be the hypotenuse of a right triangle that is formed by the rise and run of the line.
Rise = a = 3 units
Run = b = 6 units
Line = c
Therefore:
c² = 3² + 6²
c² = 9 + 36
c² = 45
c = √45
c = 6.7 units.

Find the value of m and n so that tha function . = + −x a solution of Given differential equations ′′ − ′ − = 0 () = , ′() = 2
Question:
Determine the value of m and n so that the following system of linear equation have an infinite number of solutions.
[tex](2m-1)x+3y-5=0[/tex]
and
[tex]3x+(n-1)y-2=0[/tex]
Answer:
[tex]m=\frac{17}{4}[/tex]
[tex]n = \frac{11}{5}[/tex]
Step-by-step explanation:
Given
[tex]3x+(n-1)y-2=0[/tex]
[tex](2m-1)x+3y-5=0[/tex]
Rewrite both equations:
[tex]3x + (n - 1)y = 2[/tex]
[tex](2m - 1)x + 3y = 5[/tex]
For the expression to have a solution, the following condition must exist:
[tex]\frac{3x}{(2m - 1)x} = \frac{(n-1)y}{3y}= \frac{2}{5}[/tex]
Split to 2
[tex]\frac{3x}{(2m - 1)x} = \frac{2}{5}[/tex]
[tex]\frac{(n-1)y}{3y}= \frac{2}{5}[/tex]
Cross Multiply
[tex]5 * 3x = 2 * (2m - 1)x[/tex] -- (1)
[tex]5 * (n -1)y = 2 * 3y[/tex] -- (2)
Solving (1)
[tex]5 * 3x = 2 * (2m - 1)x[/tex]
Divide both sides by x

Luis is filling his half-empty swimming pool with water at a rate of 220 gallons per hour. After 33 hours the pool contains 855 gallons of water. What is the equation in point-slope form that relates the amount of water in the pool, y, to the number of hours, x, that Luis has been filling the pool?
What is the equation in standard form?
Answer:
[tex]y - 220x = -6405[/tex]
Step-by-step explanation:
Given
[tex]Rate = 220[/tex]
At [tex]time = 33\ hours[/tex], [tex]gallons = 855[/tex]
Required
Determine the equation
The rate means slope (m).
So:
[tex]m = 220[/tex]
From the question, x represents time and y represents the amount of water.
So:
[tex]x=33[/tex] when [tex]y = 855[/tex]
Or:
[tex](x_1,y_1) = (33,855)[/tex]
The equation is determined using:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - 855 = 220(x - 33)[/tex]
[tex]y - 855 = 220x - 7260[/tex]
Collect Like Terms
[tex]y - 220x = 855 - 7260[/tex]
[tex]y - 220x = -6405[/tex]
Hence, the equation in standard form is:
[tex]y - 220x = -6405[/tex]
