Martha types a 4 digit code into a keypad to unlock her car. the code uses the numbers 1 and 0. if the digits are selected at random, what is the probability of getting a code with exactly two 0’s?

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

found it xd it ok yt

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

middle maybe?
