Answer:

(e) 39

Step-by-step explanation:

The expected value (or the average number) of impulse purchases per day is given by the probability of an impulse purchase being made (6%) multiplied by the daily number of customers (650):

E(X) =P(X)* n\\E(X) = 0.06*650\\E(X) = 39

The average number of impulse purchases is 39 per day.

What is the measure of AC?
artcher [175]

Answer:

AC = 10

Step-by-step explanation:

Do you really need the explanation it seems like you are taking a test. I answered one of your questions a few seconds ago.

a^2+b^2=c^2.

8^2 + 6^2 = c^2

64 + 36 = c^2.

100 = c^2.

Square root of it all equals to

c = 10.
