Question

Regression equation : y = 3.915(1.106)x. which two equations below could you solve to find d, the number of days it takes the water lily population to double? 2 = 3.915(1.106)d 7.830 = 3.915(1.106)d 7.830 = 3.915(2)d 2 = 1.106d

Answer 1

Answer: 1.106D

Step-by-step explanation: 7.830=3.915(1.106)D and 2 = 1.106D

Answer 2

The number of days it takes the water lily population to double will be 3.915.

What is a regression equation?

The equation is written as Y= a + bX, where Y is the dependent variable and X is the independent variable.

This is an algebraic idea; imagine the initial number was x and the new number is 2x. If the constant rate of growth is r and the time is D, the function expressing growth will be:

$2x=x(r)D\\\\ 7.830=3.915(1.106)D\\\\ 7.830=3.915(2)D$

Hence the number of days it takes the water lily population to double will be 3.915.
