a. 7.5
b. 5
c. 2.5
sorry if it is in correct
30 divided by 4 = 7.5
10 divided by 2 = 5
7.5-5=2.5
1 meter = 1000 millimeters
Area = length * width
A = lw
1000 = l * 841
1.19 = l
Length = 1.19 millimeters
The expected winning on an $1 ticket would be $0.326 or about 33 cents.
First, we need to find the total of all of the prize money:
1(160000) + 2(20000) + 11(4000) + 21(800) = 260800
Divide this total by the 800,000 tickets and you get 0.326.
