Kennedy’s car used 11 gallons to travel 319 miles. How many gallons of gas would she need to travel 406miles

makvit [3.9K]

In the US, the gallon is a unit of measurement for liquids like milk, fuel, and water. If the petrol in your automobile is nearly empty, you should stop and get at least a few more gallons. A gallon is equal to 4 quarts, or 3.785 liters, of liquid.

<h3>Explain about the gallons?</h3>

Eight pints make up a gallon, which is a unit of measurement for liquids. It is equivalent to roughly 4.546 liters in Britain. It is roughly equivalent to 3.785 liters in America.

A gallon of water in the US weighs 8.345 pounds or 3.785 kilogram at 17 degrees Celsius, while a gallon of water in the imperial system weighs 10.02 pounds or 4.545 kilogram. The Imperial gallon weighs 16.6% less than 1 US gallon (gal).

Gas consumption is affected by driving on hills and mountainous terrain, by the state of the roads (such as stop-and-go city traffic or highway travel), and by the weather (such as high winds or snow). We can safely infer that under a number of

Answer is 14 gallons of gas need to travel 406 miles

A simple linear regression analysis was conducted to predict the Exam 3 score of students in STA 2023 based on their Exam 1 scor

Katena32 [7]

Answer:

Option A) As the Exam 1 score increases by 1 point, the student's Exam 3 grade will increase, on average, by 0.4845 points.

Step-by-step explanation:

We are given the following in the equation:

A simple linear regression analysis was conducted to predict the Exam 3 score of students in STA 2023 based on their Exam 1 score.

Thus, Exam 3 score becomes the dependent variable and exam 1 score is the independent variable.

The regression equation is given by:

$\hat{y} = 50.57+0.4845x$

Comparing the equation to a linear equation:

$y = mx + c$

m = 0.4845

c = 50.57

Where m is the slope and tells the rate of change and c is the y intercept that is the value of y when x is 0.

When, there is a increase in x, we can write:

$\hat{y}(x) = 50.57+0.4845x\\\hat{y}(x+1) = 50.57+0.4845(x+1)\\\hat{y}(x+1) - \hat{y}(x) = 50.57+0.4845(x+1)-(50.57+0.4845x)\\\hat{y}(x+1) - \hat{y}(x) = 0.4845$

Thus, the slope of equation can be interpreted as:

Option A) As the Exam 1 score increases by 1 point, the student's Exam 3 grade will increase, on average, by 0.4845 points.
