Suppose a bus arrives at a bus stop every 35 minutes. if you arrive at a bus stop at a random time, what is the probability that you will have to wait at least 20 minutes for the bus?
a- 3/7
b- 1/2
c- 5/7
d- 3/4

Step-by-step explanation:

Given : Suppose a bus arrives at a bus stop every 35 minutes

To Find: If you arrive at a bus stop at a random time, what is the probability that you will have to wait at least 20 minutes for the bus?

Solution:

A bus arrives at a bus stop every 35 minutes.

You arrive at a bus stop at a random time.

So, probability that you will wait at most 20 minutes =

So, The probability that you will wait at least 20 minutes =

                                                                                               =  

                                                                                               =  

                                                                                               =  

Thus the probability that you will have to wait at least 20 minutes for the bus is    

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
