Please help me solve this
In-s [12.5K]

Step-by-step explanation:

Erase the dot points you already have. We are supposed to substitute those values in the right side of problem 1 into the function as x.

For example if x=-4

- ( - 4) + 5 = 9

If x=-2

- ( - 2) + 5 = 7

If x=0

0 + 5 = 5

- 2 + 5 =  3

- 4 + 5 = 1

So our point should be

-4,9

-2,7

0,5

-2,3

-4,1.

The range is all possible y values in a function. Since this is discrete and we are given the domain, our range will just be the y value of the points you graphed.

(9,7,5,3,1)

Observation that we can make is min = 10, max = 19, range = 9, Maximum frequency of a number is 12, Average = 12.9, median = 12, mode = 12 it is slightly skewed on the right.

Step-by-step explanation:

  • It is imperative to create a data in a tabular column before analyzing.
  • Once the data is created use tally marks or frequency distribution.
  • Frequency distribution helps the data to provide occurrence of event.
  • Very important to number which is a counting numbers are discrete.
  • Continuous of data are ones which are in decimal.
  • Descriptive statistics is the 1st level of Statistics.
  • It finds, where the data stands. Minimum, Maximum is understandable.
  • Range is at what level data is expanded.
  • Average is the one numeric of a number.
