Thus to find out the new price, we have to add old price and rise in price
On solving we get,
On converting to mixed fraction,
Hence, the new price is , so option A is correct.
Answer:

b
The number of cars the highway patrol officer would watch before a car that is seen is
The standard deviation is
gg
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is
The speed limit is
Generally the probability of getting a car that is moving with speed greater than the speed limit is mathematically represented as
=>
=>
Here
So
=>
From the z-table
So
Generally the probability of getting a car that is not moving with speed greater than the speed limit is mathematically represented as
=>
=>
Generally the probability of getting 5 cars that are not speeding is mathematically represented as
=>
=>
Generally the number of cars that the highway patrol officer is expected to watch until the first car that is speeding is gotten is mathematically represented as
=>
=>
Generally the standard deviation is mathematically represented as
=>
=>
