Answer:
5 units
Step-by-step explanation:
Image of the trapezoid is attached.
To find the height of the trapezoid (image attached), let's take the formula for area of a trapezoid.
The formula for area of a trapezoid is:

Here, a and b represents the bases of the trapezoid.
a = 6
b = 10
h which represents height is unknown.
A = 40
Substitute figures:



Solve for h:


The height of the trapezoid is 5 units
Answer: a) 30, b) 0.2138, c) 0.0820
Step-by-step explanation:
Since we have given that
X be the number of calls in 1 hour = 60 minutes
Rate of one call every two minutes.

(a) What is the expected number of 911 calls in one hour?

(b) What is the probability of three 911 calls in five minutes? If required, round your answer to four decimal places.

Number of calls = 3
So, P(X=3) is given by

(c) What is the probability of no 911 calls during a five-minute period? If required, round your answer to four decimal places.

Hence, a) 30, b) 0.2138, c) 0.0820
20% * 158.08 =31.616
or
20% * £158.08 =48.1005824
