The unit rate of boxes produced per hour by the machine is 1200 boxes per hour. This is obtained by multiplying the number of boxes made in 15 minutes (300 boxes) by 4 to account for the 4 15-minute intervals in an hour.
To find the unit rate of boxes produced per hour, we first need to determine how many minutes are in an hour. There are 60 minutes in 1 hour.
Then, we need to figure out how many 15-minute intervals fit into 60 minutes. To do this, we divide 60 by 15, which gives us 4. This means there are 4 15-minute intervals in an hour.
Given that the machine makes 300 boxes in 15 minutes, we multiply this quantity by 4 to find out how many boxes it makes in an hour. Therefore, the expression for the unit rate in boxes per hour is 300 boxes * 4, which equals 1200 boxes per hour.

Answer:
Choice D
Step-by-step explanation:
probability of B given A
given you win the first race, you win the second race
Answer: The correct option is
(D) The probability that you win the second race given that you win the first race.
Step-by-step explanation: We are given the following two events :
A : You win the first race
B : You win the second race.
We are given to select the statement that represents P(B\A).
We know that
for any two events R and Q, the probability P(Q\R) represents the probability of happening of event Q given that the event R has already happened.
Therefore, for the given two events A and B,
the probability P(B\A) represents the probability that you win the second race given that you win the first race.
Thus, (D) is the correct option.
