Leo wants to determine the average number of texts middle school students sendinatay Srce al modesto students are erroiled in history. he randomly surveyed 4 students from schof Mr Beressertgate story
diasses. Ms. Lopez and Mrs. Frank also teach eighth-gade history What should be cotoesure his des
representative of all middle school si berts
He should take the sample as is because he randomly surveyed suderts in ech of Mr. Bress desses
He should also take a sample from Ms Lopeisand Mrs Franks desses sotatach sicert has the same
chance of being chosen
He should also take a sample from each of the other history desses in all of the che gates in te medesco
He should survey all the students in all the history desses to make sure recolleas enough ata

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

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
