Alexa surveyed 140 of the students in her school about their favorite color. Students could choose between red and purple. 91 students said their favorite color was purple. What percentage of the surveyed students said their favorite color was red?

step-by-step explanation:

no of data

divide by no of mode

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

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

if i put something wrong your not gonna like it so rather not say nothing.
