If a toy that costs $2.99 is at a 30% discount then you first need to make 30% a decimal.
30% = .3
Now multiply $2.99 by .3 to find the discount which is .897
Since .897 has a thousandths place we need to round that which would make it 90 cents.
Now we know there is a 90 cent discount on a $2.99 toy.
take $2.99 - 90 cents = $2.09
The toy costs $2.09 after a 30% discount
Answer:
The answer is below
Step-by-step explanation:
a) For the person to get to New York city, the person must arrive at a time after the train to Boston has left and before the train to New York leaves. Between 7 and 8 am, there is a total of 60 minutes. For the person end up in New York city he has to arrive at the train station between the following intervals:
7:05 to 7:15 or 7:20 to 7:30 or 7:35 to 7:45 or 7:50 to 8:00
Let X represent the minutes the passenger arrives between 7 am to 8 am, hence:
P(goes to New York) = P(5 < X < 15) + P(20 < X < 30) + P(35 < X < 45) + P(50 < X < 60) = 10/60 + 10/60 + 10/60 + 10/60 = 40/60 = 2/3
b) As explained in part A, Let X represent the minutes the passenger arrives between 7 am to 8:10 am. But since time uniformly distributed between 7:10 and 8:10 am, this means 10 < X < 70:
For the person end up in New York city he has to arrive at the train station between the following intervals:
7:10 to 7:15 or 7:20 to 7:30 or 7:35 to 7:45 or 7:50 to 8:00 or 8:05 to 8:10
P(goes to New York) = P(10 < X < 15) + P(20 < X < 30) + P(35 < X < 45) + P(50 < X < 60) + P(65< X <70)= 5/60 + 10/60 + 10/60 + 10/60 + 10/60 + 5/60= 40/60 = 2/3
