Answer:
2658936 * 
Step-by-step explanation:
probability that the 20th person visiting the service station to purchase regular gasoline will be the 4th person to purchase regular gasoline without ethanol
probability of people who use regular gasoline without ethanol = 1/15 and will pay more ( $0.40) /gallon
The total number of customer in the service station (number of trials) X = 20
success ( r ) = 4
P = 1/15
The probability that the 20th person/customer visiting the station would be the 4th person to purchase regular gasoline without ethanol
FIND ATTACHED THE DETAILED SOLUTION
we know that, the mixture amount is the sum of 11 + p, or
11 + p = m.
we also know that, the total value is also a sum of
25.3 + 4.5p = 3.29m.
Answer:
cos θ = 4/5.
tan θ = 3/4.
Step-by-step explanation:
Given sin θ = 3/5, we can find the value for the other side of the right triangle.
Using the Pythagorean formula, we can derive the value of this other leg.
5² = 3² + x²
x = 4.
Since sin θ is O/H, the Hypoteneus is 5 and the Opposite side is 3. The Adjacent side is 4, which will be used when finding cos θ and tan θ.
cos θ= A/H --> cos θ = 4/5.
tan θ= O/A --> tan θ = 3/4.
20.75 because if you add 4.85+7.95+7.95 add that you get 20.75
