Well first you have to divide 620/20 which is 31. So his car goes 31 miles per gallon so you have 2 gallons and .25 of a gallon. So first off 2*31=62 miles then the 1/4 or .25. Multiply the 31 by .25 which is 7.75 now add 62 and 7.75 and you get how far his car can go.
62+7.75=69.75 miles
Um Plan B would be two dollars cheaper than plan A ..
I set the equations up like this :
5+2.50x=
24+1.50x=
Only because thats how many movies she plans on watching.
5+2.50(21)=57.50
24+1.50(21)=55.50
Answer: Our required probability is 0.3162.
Step-by-step explanation:
Since we have given that
n = 60
Probability of success = 
Probability that at most 39 of these relays come from supplier A would be
Hence, our required probability is 0.3162.
The correct answer would be A. There is only a 1/8th percent chance of the spinner landing on 4.
