#c

Answer:
a. 2116 miles
b. 105.8 gallons
c. $305.76
d. cost per gallon = total cost / number of gallons = total cost/105.8
Step-by-step explanation:
The round-trip distance is the sum of the distances there and back. It is double the one-way distance.
round-trip distance = 2 × one-way distance
round-trip distance = 2 × 1058 miles = 2116 miles
__
The gas used will be the distance divided by miles per gallon.
gas used = round-trip distance / miles-per-gallon
gas used = (2116 mi)/(20 mi/gal) = 105.8 gal
The cost of gas will be the product of cost per gallon and number of gallons.
cost of gas = cost-per-gallon × gallons
cost of gas = $2.89/gal × 105.8 gal = $305.762 ≈ $305.76
The relation used in the previous step can be used to find the cost per gallon. Divide that equation by gallons to get ...
(cost of gas)/gallons = cost-per-gallon
For the same trip, the number of gallons is 105.8, so the equation becomes ...
cost-per-gallon = (cost of gas)/105.8

First of all let's ook at the 36 possible outcomes and their sums.
2=1,1
3=1,2 2,1
4=1,3 ; 2,2 ; 3,1
5=1,4 ; 2,3 ; 3,2 ; 4,1
6=1,5 ; 2,4 ; 3,3 ; 4,2 ; 5,1
7=1,6 ; 2,5 ; 3,4 ; 4,3 ; 5,2 ; 6,1
8=2,6 ; 3,5 ; 4,4 ; 5,3 ; 6,2
9=3,6 ; 4,5 ; 5,4 ; 6,3
10=4,6 ; 5,5 ; 6,4
11=5,6 ; 6,5
12=6,6
Looking at the above, there are 4 sums equal to 5 out of a total of 36 sums.
Thus, probability of getting a sum equal to 5 is;
P(5) = 5/36
Now,since the cubes are rolled 540 times, number of times a sum equal to 5 will appear will be;
(5/36) x 540 = 75 times
6x
