Hi everyone! I need your help with my 01.04 Geometry DBA for FLVS. I studied all the material I am just wondering what should I focus on. Any advice?

The administrator of a large assisted living facility wanted to know the average age of the residents living at the facility. he randomly selected 12 residents and determined their age, listed here: 80, 65, 75, 83, 68, 73, 88, 79, 94, 72, 79, 68 what's the average age of the sample of residents? a. 79 years old b. 68 years old c. 75 years old d. 77 years old

Which of the following is the true for f(x) = 5cos

How is working backward similar to solving an equation?
