Step-by-step explanation:
See attachment for complete question.
To determine which car has more gas efficiency, we have to calculate the slope of each car.
Vehicle 1: Legend
Take any two corresponding points from the table
![(x_1,y_1) = (4,72)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%20%284%2C72%29)
![(x_2,y_2) = (12,216)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%20%2812%2C216%29)
The slope is then calculated using;
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
![m = \frac{216 - 72}{12 - 4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B216%20-%2072%7D%7B12%20-%204%7D)
![m = \frac{144}{8}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B144%7D%7B8%7D)
![m = 18](https://tex.z-dn.net/?f=m%20%3D%2018)
<em>This implies that this vehicle (legend) travels 18 miles per gallon of gas</em>
Vehicle 2: Supreme
Take any two corresponding points from the graph
![(x_1,y_1) = (0,0)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%20%280%2C0%29)
![(x_2,y_2) = (15,250)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%20%2815%2C250%29)
The slope is then calculated using;
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
![m = \frac{250 - 0}{15 - 0}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B250%20-%200%7D%7B15%20-%200%7D)
![m = \frac{250}{15}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B250%7D%7B15%7D)
![m = 16.7](https://tex.z-dn.net/?f=m%20%3D%2016.7)
This implies that this vehicle (supreme) travels 16.7 miles per gallon of gas
<em>Base on the calculations above, Victor should buy Legend because it has a better unit rate</em>
Answer: C. Subtraction Property of Inequality
Answer:
Choice B is correct
Step-by-step explanation:
The Interquartile Range (IQR) for Florida, 11, is greater than the IQR for Australia, 4.
The spread of a data set is a measure of the dispersion or variability of the data set. The spread can be measured by various statistical quantities depending on the nature of the data (skewed or symmetric);
The IQR
Variance
Standard Deviation
Range
A box plot is a graphical representation of the five number summary;
The minimum, first quartile, median, third quartile, and the maximum value in that order.
The IQR is defined as;
third quartile - first quartile
With this definition, the Interquartile Range (IQR) for Florida is;
28 - 17 = 11
while the Interquartile Range (IQR) for Australia is;
14 - 10 = 4
Therefore, the Interquartile Range (IQR) for Florida, 11, is greater than the IQR for Australia, 4.
