Answer:
defines the gallons of the gas consumed by the old car in one year.
Step-by-step explanation:
If I purchase a car, I will definitely concentrate on a factor that is gas consumed by the car in a year.
As per statement given in the question if gas is $3.45 per gallon and I drive an average of 18000 miles per year.
If x miles per gallons is the average of the old car and y miles per gallons is the average of of new car.
Then total difference in gallons of the gas consumed by the old and new cars will be represented by the equation.
g(x) = 3.45 - 3.45
Here, defines total number of gallons of the gas consumed by the old car in one year.
Answer:
Option E - Box plot E
Step-by-step explanation:
Given : Data,
67, 66, 64, 62, 60, 56, 54, 50, 46, 42, 41, 40, 40, 38, 35, 21, 19
To find : Which choice below is a boxplot for the following distribution?
Solution :
Step 1- Arranging the data from lowest to highest,
{19,21,35,38,40,40,41,42,46,50,54,56,60,62,64,66,67}
Step 2 - Find the median of the data
As the data is odd numbers so the median is th term.
term.
9th term is 46
∴
Step 3 - To find Upper quartile and lower quartile
Lower quartile data set is the median of the upper terms from median
{19,21,35,38,40,40,41,42}
Median of the set is
∴
Upper quartile data set is the median of the lower terms from median
{ 50,54,56,60,62,64,66,67}
Median of the set is
∴
We have plot the box plot attached below.
Our box plot is matched with Box plot E.
Therefore, Option E is correct.
