Answer:
y = 1.754 + 1.001 x
Step-by-step explanation:
The equation of Regression equation is of the form of:
y = a + bx
where, a is intercept and b is slope
The formula for a and b is given by,
![a = \frac{\sum Y \sum X^2- \sum X \sum XY}{n\sum X^2-(\sum X)^2} \\and, b = \frac{n\sum XY - \sum X \sum Y}{n\sum X^2-(\sum X)^2}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B%5Csum%20Y%20%5Csum%20X%5E2-%20%5Csum%20X%20%5Csum%20XY%7D%7Bn%5Csum%20X%5E2-%28%5Csum%20X%29%5E2%7D%20%5C%5Cand%2C%20b%20%3D%20%5Cfrac%7Bn%5Csum%20XY%20-%20%5Csum%20X%20%5Csum%20Y%7D%7Bn%5Csum%20X%5E2-%28%5Csum%20X%29%5E2%7D)
Thus, a = 1.754
and b = 1.001
Thus, Regression Line is given by,
y = 1.754 + 1.001 x
Now plotting these line:
Answer:
239=5
478=10
956=20
Step-by-step explanation:
Gianna's car can travel 478 mi with 10 gallons of gas
so, 47.8 mi with 1 gallon
by dividing 239 by 47.8 miles/gallon we get the answer 5 miles.
if we multiply 20 gallons by 47.8 mi/gallon #e get the answer 956 miles.
