Answer:

D. 28.5 %

Step-by-step explanation:

The formula for it  is

                  120

P(X ≤ 120) = ∑     250C120 *0.5^120 * 0.5*130

                   0  

which  is best found using a binomial calculator.

I used  one on line. The answer is D.

Delia went to a market to buy 4.5 pounds of sliced fruit in a container she paid with a $20 bill and a $5 bill and received $5.2
valina [46]

One pound of the item will cost 4.74 bill

Step-by-step explanation:

In this problem, we are told that Delia bought 4.5 pounds of fruit

and paid with a toa total bill of 20+5= 25 bill

and also she received a  change of 3.67

this means that the item she bought cost 25-3.67= 21.33bill

now if 4.5 pounds of items cost 21.33 bill

then 1 pound will cost Xbill

cross multiply and solve for Xbill

X= 21.33/4.5

X= 4.74 bill

One pound of the item will cost 4.74 bill
