Answer:
a) during the 3rd season the populations will be the same
b) after 11 1/4 seasons the second species of fish will be eliminated
Step-by-step explanation:
1) y = 25x + 255
2) y = -40x + 450
the above linear equations model the statements from the problem
we can find out when the two populations will have the same amount by graphing them and finding the point of intersection or by setting them equal to each other:
25x + 255 = -40x + 450
add 40x to each side to get:
65x + 255 = 450
subtract 255 from each side to get:
65x = 195
x = 195/65
x = 3
To find the season when the second species is eliminated we can use the second equation and set 'y' equal to zero and solve for 'x':
0 = -40x + 450
subtract 450 from each side to get:
-450 = -40x
x = -450/-40
x = 11.25
Remember from algebra, that the slope is the “m” in the formula y = mx + b. In the linear regression formula, the slope is the a in the equation y' = b + ax. They are basically the same thing. So if you're asked to find linear regression slope, all you need to do is find b in the same way that you would find m.

Kindly check explanation
Step-by-step explanation:
Now assume an economic scenario whereby the market price of a certain goods has experienced inflation probably due to increased demand of the commodity. For instance, the market price of the nose masks and hand sanitizers went up by more than 25% at some time during the early stages of corona pandemic outbreak. This means that;
Sanitizer which were being sold at $5 before the pandemic sold for about (1 + 0.25) * $5 ; 1.25 * $25 = $6.25
