Answer:

The resulting residual value is e=-40.24.

Step-by-step explanation:

The residual value e for a regression model is defined as the difference between the real value y and the predicted value yp:

$e=y-y_p$

The predicted value for DISTANCE=0.43 miles is:

$RENT = 1200.4326 - 256.2567\cdot DISTANCE\\\\RENT(0.43) = 1200.4326 - 256.2567\cdot 0.43\\\\RENT(0.43) = 1200.4326 - 110.1904=1090.2422\\\\$

Then, if the real value is $1,050, the residual value is calculated as:

$e=y-y_p\\\\e=1050-1090.2422=-40.2422$

The difference of a number multiplied by 2 tens and 3 sevens is 119. What is the number?

Elan Coil [88]

Your question is not clearly stated. Do you mean the difference between 10 * 10 * x, and 7 * 7 * 7 *x ? Then the number is x = 119/243. That's about 0.48971... in decimal form.

It's confusing when you say the "difference of a number". Differences are BETWEEN two numbers. See what I mean?
