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.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
