Which one of the following data sets has more than one mode?
A. {10, 20, 30, 30, 40, 50, 50)
B. {10, 20, 30, 40, 50, 70, 70)
C. {20, 20, 30, 30, 30, 40, 40}
D. {10, 20, 30, 40, 50250, 70)

A

Step-by-step explanation:

30,30 & 50,50

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
