Select all the measures of central tendency and measures of variability that are affected by outliers. mean median mode range interquartile range mean absolute deviation

Measure of central tendency

Mean, median, mode

Measures of variability

Range

Interquartile range

Mean absolute deviation

Step-by-step explanation:

Statistics are tools used for analysing data. It requires collection, analysis and interpretation of data.

The measures used in analysing this datas are divided into two known as he measures of central tendency and measures of variability.

This datas can either be grouped or ungrouped data

The following are measures of central tendency

- Mean: This is used to find the average set of datas or samples collected.

- Median: median is the middle number among the datas after rearranging either in ascending or descending order

- Mode: mode is the value of the data which occurs the most. The value with the highest frequency

The following are measures of variability

- Range: This is the difference between the highest and the lowest value of the data set.

The remaining are the interquartile range and mean absolute deviation. Mean deviation measures the accuracy and variability of the data. It measures precision and accuracy of data.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
