PLEASE HELP On Monday a marine biologist took a random sample of 50 fish from a pond and tagged them. On Tuesday she took a new sample of 100 fish. Among them were 4 fish that had been tagged on Monday.

a. What comparison does the ratio 4/100 represent?

b. What is the ratio of the number of fish tagged on Monday to n, the estimated total number of fish in the pond?

c. Use a proportion to estimate the number of fish in the pond.

What is the missing step in this proof ?

Which of the following describes the graph of y--4x-36 compared to the parent square root function? stretched by a factor of 2, reflected over the x-axis, and translated 9 units right stretched by a factor of 2, reflected over the x-axis, and translated 9 units left stretched by a factor of 2, reflected over the y-axis, and translated 9 units right stretched by a factor of 2, reflected over the y-axis, and translated 9 units left save and exit next submit
