A
(a) You're looking for
where
Customers arrive at a mean rate of 6 customers per 10 minutes, or equivalently 12 customers per 20 minutes, so
Then
(b) Now you want
This time, we have
so that
B
(a) In other words, you're asked to find the probability that more than 1 customer shows up in the same minute, or
with
So we have
C
(a) Similar to B, you're looking for
with
so that
5 cubed ( or an exponent of three )
Answer:
The slope will be 1/2.
Step-by-step explanation:
Sine the lines are perpendicular, the slope of the green line will be the negative reciprocal of the slope of the red line. To find the negative reciprocal of -2, first change the sign. Since the slope is negative, make it positive 2. Then to find it's reciprocal, divide 1 by your answer. 1 divided by 2 is one half, s that is your answer.
