Describe what a frequency table is what is used for

Answers

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.

Answers

7x - 24 = -3x + 16
7x = -3x + 40

4,320 ÷ x

Answers

Answer: Option C.

Step-by-step explanation:

x = 10.8

A. = 4,320 ÷ x

= 4,320/10.8

= 400

Option A is incorrect.

B. = 288/x + 16

= 288/10.8 + 16

= 42.7

Option B is incorrect

C. = (x² ÷ 18) + 33.52

= (10.8² ÷ 18) + 33.52

= 40

Option C is correct

D. = (1,752 ÷ x) – 162/29

= (1,752 ÷ 10.8) – 162/29

= 156.6

Option D is incorrect

E. = x/12 + 36

1. Separate the number 58 into three parts so
that the second number is 2 less than the
first number which is one half the third
number.

Answers

Answer:

2nd number = 13

First number = 15

3rd number = 30

Step-by-step explanation:

Let

2nd number = 1/2x - 2

First number = 1/2x

3rd number = x

Total = 58

x + 1/2x + 1/2x - 2 = 58

x + x+x/2 = 58 + 2

x + 2/2x = 60

x + x = 60

2x = 60

x = 60/2

= 30

x = 30

2nd number = 1/2x - 2

= 1/2*30 - 2

= 15 - 2

= 13

First number = 1/2x

= 1/2*30

= 15

3rd number = x

= 30

Write an expression for the length of the third side of an isocoles triangle

Answers

Answer:

[tex]y = 180 - 2x[/tex]

Step-by-step explanation:

Required

Triangle: Isosceles

Required

An expression for the third side

Let the equal sides be x and the third side be y

From triangle sum theorem, we have the following expression:

[tex]x + x + y = 180[/tex]

[tex]2x + y = 180[/tex]

Subtract 2x from both sides

[tex]-2x +2x + y = 180 - 2x[/tex]

[tex]y = 180 - 2x[/tex]

Hence, the third side of an isosceles triangle is: [tex]y = 180 - 2x[/tex]

Step-by-step explanation:

Use the compound interest equation with a negative interest rate:

A = P(1 + r/n)^(n)(t)

Let n be 1 since we're looking for a specific year.

100 = 250(1 - 0.07)^t

100/250 = (0.93)^t
