Answer:

No

Now for the first toss, there is a likelihood of 50%, for the second toss too there will be a likelihood of 50%.

This is different from the fact that for every 2 throws there must be a head showing up

Maria bought g gallons of gasoline for ​$3.95 per gallon and c cans of oil for ​$4.45 per can. a. What expression can be used to
Furkat [3]

Answer:

a.) Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )

b.) Total amount spent by Maria = $ 74.02

Step-by-step explanation:

As given,

Cost of gasoline = $ 3.95 gallon

Cost of oil per can = $ 4.45

Also given,

Maria bought g gallons of gasoline and c cans of oil

⇒ Total cost of g gallons of gasoline = g×3.95 = $3.95g

   Total cost of c cans of oil  = c×4.45 = $4.45c

Now,

a.)

Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )

b.)

As given ,

Maria buy gasoline , g = 8.6 gallons

Maria buy cans of oil , c = 6

So,

Total amount spent = $ 3.95(8.6) + 4.45(9)

                                = $ 33.97 + 40.05 = $ 74.02

⇒Total amount spent by Maria = $ 74.02
