Answer:
see the procedure
Step-by-step explanation:
we have
where
c -----> the cost in dollars
g ----> the number gallons of gas purchased
1) For g=1 gal
substitute the value of g in the equation and solve for c
The pair (1,2.95) fit the relationship
2) For g=3 gal
substitute the value of g in the equation and solve for c
The pair (3,8.85) fit the relationship
3) For g=5 gal
substitute the value of g in the equation and solve for c
The pair (5,14.75) fit the relationship
4) For c=$20.65
substitute the value of c in the equation and solve for g
The pair (7,20.65) fit the relationship
Answer:
= 
Step-by-step explanation:
Given: 
We have to find the value of the given fraction which can be done by dividing the denominator value with the numerator value
The power of 8 is '1', so, the value of numerator is 8.
The value of the fraction is calculated by dividing 3 by 8.

The probability that the contestant wins at least one car is 3/5.
<h3>What is the probability?</h3>
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
For 1 car, we consider two possible outcomes:
P(1 car) = 2/6 x 4/5 + 4/6 x 2/5
P(1 car) = 8/15
For no car in either door
P(no car) = 4/6 x 3/5
P(no car) = 2/5
The probability that the contestant wins at least one car is the sum of the probability of one car and the probability of two cars:
P(2 cars) = 2/6 x 1/5
= 1/15
P(1 car) + P(2 cars) = 8/15 + 1/15
= 3/5

Answer:
$4.1
Step-by-step explanation:
To find the Unit Rate, you have to find how much it cost of 1 lb. So, you have to divide 16 and 3.99
16/3.99
= 4.01002506
≈ $4.1
