A population of song sparrows contains 30 individuals, 10 of which carry gene A, 12 carry gene B, and the rest carry gene C. DNA is taken from 4 individuals. What is the
probability 2 carry the same gene, and the other two carry diffrent genes from the rest?

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

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

15.36 per mile

but forgot to round

i am pretty sure
