Supposed that prices of a certain model of new luxury cards are normally distributed with a mean of 150000. Find the probability of the buys who paid between 148200 and 151800 of the standard deviation is 1800

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

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

i have no idea just need points sorry
