Thus, distribution is a function that shows the possible values for a variable and how often they occur and categorical values are summarized by counts and/or percents
In statistics, the distribution is a function that shows the possible values for a variable and how often they occur.
The distribution of a data set is the shape of the graph when all possible values are plotted on a frequency graph. Usually, we are not able to collect all the data for our variable of interest. Therefore we take a sample. This sample is used to make conclusions about the whole data set.
The categorical variable is a data in which individuals are placed into groups or categories.
One way to summarize categorical data is to simply count (frequency), or tally up, the number of individuals that fall into each category. Another way is to show the percentage of individuals who fall into each category, thereby creating a relative frequency.

Answer:
1.) k + 516
2.) 2n - 4 = 3
3.) 57 - 2s
4.) 9h = 153
5.) c = 5n
Step-by-step explanation:
All of the problems given require you to set up an expression or equation. Expressions have a variable and a coefficient or a constant. Equations also have a variable, coefficient or constant but also include an equal sign.
1.) last year's miles = k, this year = 516, so total: k + 516
2.) twice the difference of a number and 4 equals 3
twice a number = 2n; difference of this number and 4: 2n - 4; equals 3: =3
2n - 4 = 3
3.) 57 decreased: 57 -; twice her savings: 2s: 57 - 2s
4.) 153 is: 153 =; the product of height and 9: 9h, so 9h = 153
5.) notebooks 'n', were $5 each: 5n; total cost = c, so 5n = c
