Masteriza [31]3 years ago
3 0

Answer:

a) Mean is equal to the median, 72 inches

b) The Mean better represents this distribution.

Step-by-step explanation:

a) Finding the mean of the data

(66 + 68 + 70 +72 +74 + 76 + 78 )/ 7

=504/7 =72

The median is the center value

66,68 ,70 ,72 ,74 , 76 , 78

median is 72

Mean is equal to the median

b)

Mean better represents this distribution because this data is normally distributed.If plotted, a normal distribution curve is obtained with most of the values seen to cluster around the mean value.

The prism below is made of cubes which measure 1/3 of an inch on one side what is the volume
EastWind [94]

Answer:

Volume of rectangular prism = 10/9 inch³

Step-by-step explanation:

Given:

Size of each cube = 1/3 inch

Find:

Volume of rectangular prism

Computation:

Length of rectangular prism = 2 x [1/3]

Length of rectangular prism = 2/3 inch

Width of rectangular prism = 3 x [1/3]

Width of rectangular prism = 3/3

Width of rectangular prism = 1 inch

Height of rectangular prism = 5 x [1/3]

Height of rectangular prism = 5/3 inch

Volume of rectangular prism = Length x Width X Height

Volume of rectangular prism = [2/3] x [1] x [5/3]

Volume of rectangular prism = 10/9 inch³
