Answer:
21%
Step-by-step explanation:
Actually there are three levels of process here.
If 100 calls are made only 70 calls are completed (since 30%not completed)
Out of these 70 completed we find that 40% i.e. 28 calls to a woman and 30% i.e. 21 go to a man.
28 females and 21 males
Out of 28 females 45% buy something =
Out of 21 males 40% buy something =
Total percent of calls result in a sale =
So 21% of calls result in a sale
Well, if you look at the graph, when x = -1, y or f(x) = 4.
and when x = 2, y = 0.
and when x = 2, y = 0.
