The table shows the results of a biologist who captures and tags lake trout, and then sets them free. What is the trout populati
zloy xaker [14]

Answer:

A.) About 90

Step-by-step explanation:

From the given table, the biologist tagged 150 trout. Also, he recaptured a total of 100 trouts of which 60 were recaptured with tags.

Thus, let the trout population in the lake be represented by x,

    \frac{60}{100} =  \frac{x}{150}

Cross multiply to have;

 100 × x = 60 × 150

  100x = 9000

Divide both sides by 100,

 x = \frac{9000}{100}

    = 90

Therefore, the trout population is about 90 in the lake.

Which function has the same y-intercept as the function
ddd [48]
The answer is 6x-7y=21

In order to find this answer you need to convert the answer choices into y intercept form by isolating the y variable to one side of the equation.
6x-7y=21
-7y=-6x+21
y=6/7x-3
As you can see when you change the form of this equation, the y intercept is -3.
