The linear relationship which exists between the change in weight and number of days of hibernation in a hedgedog can be modeled using the equation y = - 0.03 + 0
- Change in weight per day of hibernation = - 0.03
- Change in weight for 115 days = - 3.45 ounces
A linear model can be created using the data in the table given using a regression calculator or excel ;
The linear model obtained in the form y = m + bx is :
- y = - 0.03x + 0
- y = change in weight
- x = number of days of hibernation
- Intercept = 0
- Slope = -0.03
- The slope value of the function gives the change in weight value per number of days of hibernation ; which is -0.03.
- Using the regression equation, substitute, the vlaue of x = 115
- -0.03(115) + 0 = - 3.45
Therefore, the change in weight after 115 days of hibernation is - 3.45 ounces.

Answer:
<h3>numbers of
Ostrich he keep =
725</h3>
<u>Step-by-step explanation:</u>
- Area of field = 30 × 155 + 90 × 45
- Area of field = 4650 + 4050
- Area of field = 8700 m²
numbers of Ostrich = 8700 ÷ 12
numbers of Ostrich = 725
Well, the commission should total $1,800. This is one tenth of what he sells, so he must sell $18,000 value of merchandise.
