From the whole population of automobiles, 30% fail emission test with normal performance of a car. A manufacture is selecting 15 cars to run through emission tests. Use the binomial cumulative distribution function to calculate the probability for each number of failures possible. From the distribution, how many cars can fail the test before we conclude there is a malfunction

lol

step-by-step explanation:

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

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

a
