Answer:
A has the highest unit price
Step-by-step explanation:
To find unit prices/rates, you have to divide the price by the ounces.
So; $3.10/20 = 0.16
$3.95/32 = 0.12
$5.45/48 = 0.11
Hope this helps!
Answer:
Option B is the answer
am not really sure though
Answer:
E(X) = 17.4
Step-by-step explanation:
We can calculate the expected value of a random X variable that is discrete (X takes specific values ) as:
E(X) = ∑xp(x) where x are the specific values of x and p(x) the probability associated with this x value.
In this way the expexted value is
E(X) = ∑xp(x) =(16*0.6)+(18*0.3)+(20*0.2) = 8+5.4+4 = 17.4
