Answer:
Step-by-step explanation:
Given that St. Mary's Church is holding a raffle in which 1172 tickets have been sold at a cost of $2.00 each.
Three prizes will be awarded: 1 for S500;1 for $250; 1 for $125.
Thus total number of tickets = 1172
Of these prize winning are 3
i.e. Tickets Prize $ Net win amount Prob Net win amt*prob
1 500 (500-2) =448 1/1172 448/1172
1 250 (250-2) =248 1/1172 248/1172
1 125 (125-2) =123 1/1172 123/1172
1169 0 (0-2) = -2 1169/1172 -2338/1172
Expected value = Total -1519/1172
=-1.296

Josh's monthly fuel expenses are $1,050.
<h3><u>Prices</u></h3>
Given that Josh is looking to get a new car because he decided he was spending too much on gas, and over the past year he found that he drove 7,700 miles, and at current gas prices of $4.5 he was getting about 27 miles per gallon, To determine, if he bought a vehicle that realizes 33 miles per gallon, what might be a reasonable estimate of monthly gas costs, the following calculation must be made:
- 27 = 100
- 33 = X
- 3300 / 27 = X
- 122.22 = X
- 122.22 = 100
- 100 = X
- 10000 / 122.22 = X
- 81.81 = X
- (7700 / 33) x 4.5 = X
- 233.33 x 4.5 = X
- 1050 = X
Therefore, Josh's monthly fuel expenses are $1,050.
