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:
Step-by-step explanation:
At the lying lemon used car company each salesperson makes $5.75 per hour and receives 6 1/2% commission on sales. Converting
6 1/2% to decimal, it becomes 6.5%
If a Salesperson worked for 8 hours, the amount that he would earn would be
8 × 5.75 = $46
If the salesperson sold a car for $9290, his commission would be
6.5/100 × 9290 = 0.065 × 9290 = $603.85
Total amount that the sales person would earn is
46+ 603.85 = $649.85
356,605 Rounded to the nearest hundred-thousand would be 400,000
an isosceles triangle is a triangle with two twin sides, and therefore two twin angles.
if one angle is 98°, well, we can't have another 98° angle because that makes 98+98 = 196°, and the sum of all interior angles in a triangle cannot be more than 180°.
so the other remaining angles must be the twin smaller angles, namely 180 - 98 = 82, and each twin takes half of that, namely 41°.

Answer: x = 2, y = 9
Step-by-step explanation:
y = 9x - 9 Substitute x for 2
y = 9(2) - 9 Multiply 9 with 2
y = 18 - 9 Subtract 18 - 9
Final Answer: y = 9 and x = 2
