Lillian is deciding between two parking garages. Garage A charges an initial fee of $4 to park plus $3 per hour. Garage B charge
Georgia [21]

Answer:

5 hours

Step-by-step explanation:

Lillian is deciding between two parking garages.

Let the time required to park be represented by t

A = Amount

From Garage A

A = the amount Garage A would charge if Lillian parks for t hours

B = the amount Garage B would charge if Lillian parks for t hours.

Garage A

Garage A charges an initial fee of $4 to park plus $3 per hour.

A = $4 + $3 × t

A = 4 + 3t

Garage B charges an initial fee of $9 to park plus $2 per hour.

B = $9 + $2 × t

B = 9 + 2t

The hours parked, t, that would make the cost of each garage the same is calculated by equating A to B

A = B

4 + 3t = 9 + 2t

Collect like terms

3t - 2t = 9 - 4

t = 5 hours

Therefore, the hours parked, t, that would make the cost of each garage the same is 5 hours

When you flip a biased coin the probability of getting a tail is 0.34. Find the probability of getting a head.
koban [17]

Answer:

If you want to know what the probability is to get at least one Heads, then that is the same as the probability of all the events (100%, or 1) minus the probability of getting all Tails.

There are 100 coins. 99 are fair, 1 is biased with both sides as heads. With a fair coin, the probability of three heads is 0.53=1/8. The probability of picking the biased coin: P(biased coin)=1/100.
