68. Traveling to work How long do people travel each day to get to work ? The following table gives the average travel times to
work (in minutes ) for workers in each state and the District of Columbia who are at least 16 years old and don't work at home .
a) Make a histogram to display the time travel time data using intervals of within 2 minutes, starting at 14 minutes.
b) Describe the shape of the distribution. What is the most common interval of travel times?

<u>Given</u>:
Given that the figure is a triangular prism.
The length of the prism is 4 m.
The base of the triangle is 2.5 m.
The height of the triangle is 2.25 m.
We need to determine the volume of the triangular prism.
<u>Volume of the triangular prism:</u>
The volume of the triangular prism can be determined using the formula,
where b is the base of the triangle,
h is the height of the triangle and
l is the length of the prism.
Substituting b = 2.5, h = 2.25 and l = 4 in the above formula, we get;
Thus, the volume of the triangular prism is 11.25 m³
William is 17 years old and Charmaine is 14 years old.
Step-by-step explanation:
Let x be the age of William and y be the age of Charmaine
Then
William is 3 years, older than Charmine.
x = y+3 Eqn 1
The sum of 3 times Charmaine's age and 2 times William's age is 76.
2x+3y = 76 Eqn 2
Putting x = y+3 in Eqn 2
Hence,
William is 17 years old and Charmaine is 14 years old.
