In a bag there are 22 items in total, including: 5 red triangles, 7 white circles, 3 blue circles, 1 red circles, 3 red stars, and 3 blue stars. You pick items randomly out of this bag. If you pick 2 items, what is the probability of picking first a triangle and then a blue item? 100% If you pick 5 items, what is the probability of picking 2 red stars and 3 white items? 100% If you pick 5 items, what is the probability of picking 2 red stars and 3 white items where the first item picked is a red star and the last item picked is a white item? 100%

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
