Answer:

47. 1  5/8

48. 1  1/12

Step-by-step explanation:

<em>47. </em>

<em>First, convert the denominators to be the same.</em>

8  1/2 minutes, Ruby's mile time, can be converted to 8  4/8.

<em>Then subtract.</em>

8  4/8 - 6  7/8  = 1  5/8

<em>48.</em>

<em>Make sure the denominators are the same. Both denominators can be multiplied by 3 or 4 to become 12.</em>

1  1/4 can be multiplied by 3 to get 1  3/12. And 1  1/3 can be multiplied by 4 to get  2  4/12.

<em>Then subtract.</em>

2  4/12 - 1  1/3 = 1  1/12

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
