The proportion used to find the average number of bass you would expect to live in the pond is 7/20 = x/400 solve the proportion to find the expected number of bass in the population. the expected number of bass in the population is

x=140

Step-by-step explanation:

You have to solve for x by cross multiplying. hope this helped mark me brainiest please

Expected number of bass in the population = 140.

Step-by-step explanation:

Given that

After solving we will get expected number of bass in the population as 140.

sorry not sure

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
