Answer:
B. The problem involves a combination because the order in which the letters are selected does not matter.
Step-by-step explanation:
Computation technique is a method of statistics to find possible ways of combination. In computation technique it is assumed that order does not matter and letters will be selected at random. Permutation is a statistics technique to find possible ways of combination when the order does matter. Permutation technique cannot be used when order does not matter.
The height is 6tan(60)=10.39 then plug that in to trapezoid area formula
(11+6+15)/2*10.39=166.24
Answer:
3.333333333333...
Step-by-step explanation:
Area= 1/2(base)(height)
A= 1/2(7)(2)
A= (1*2*7)/2
A= 14/2
A= 7 units squared
Hope this helps! :)
