Explanation:

1. Identify the different constellations of variables. Here there are three:

  • b
  • a
  • (none)

2. Combine coefficients of each of the different variable constellations:

  (8.1 -2.8)b +(6.7 +0.9)a +(2.5 +7)

  5.3b +7.8a +9.5

3. Perform any other operations that might be required depending on the sort of equivalent wanted. For example, one could write ...

  5.3(b +(78/53)a) +9.5 . . . . . . . shows the weight of a relative to b

A log-level model relating the natural logarithm of house price, y, to square footage was fit. The fitted model is stack ln (p r
Musya8 [376]

Answer:

$255,331

Step-by-step explanation:

Calculation for the estimated price

ln (price) =11.65 +0.000473*square foot

Square feet =1,692

First step is to find the ln (price)

ln (price) =11.65 +0.000473*1,692

ln (price)=12.450316

Last step is to calculate the Estimated price by using calculator to find the exponential of 12.450316

Estimated price=e^(12.450316)

Estimated price=$255,330.99

Estimated price=$255,331 Approximately

Therefore the estimated price of a house that is 1,692 square feet will be $255,331

What is the square of one half?
Vlad1618 [11]

Answer:

One-half squared is one-fourth.

Step-by-step explanation:

When you divide fractions, you multiply the first term by the reciprocal of the second term. In this example, instead of multiplying 1/2 by 1/4, you now multiply 1/2 by 4. Therefore, one half is equal to 2 fourths.
