Answer:

A The mode does not change.

C The mean drops from 185.3 to 172.6.

Step-by-step explanation:

Mean of original data

Mean = (160 + 175 + 166 + 180 + 172 + 178 + 174 + 170 + 178 + 300)/10 = 1853/10 = 185.3

Mean with outlier removed

Mean = (1853 - 300)/9 = 1553/9 = 172.6

The mean drops from 185.3 to 172.6 when the outlier is removed.

Mode

The mode of a data set is the value that occurs most often.

Mode = 178

The mode does not change when you remove the outlier.

Vadim26 [7]

The surface area of the square prism is 115 square inches

<h3>surface area of a pyramid</h3>

The surface area of a pyramid is equivalent to the sum of the faces of the pyramid

For the given square pyramid;

TSA = (5*5) + 4(1/2 * 9 * 5)

Simplify to have;

Surface area =25 + 4(45/2)

Surface area = 25 + 180/2

Surface area = 25. + 90

Surface area = 115 square inches

Hence the surface area of the square prism is 115 square inches
