Three national news networks are trying to estimate what percentage of
American voters support a particular presidential candidate. To estimate the
population parameter, each of the three networks collects data from a simple
random sample of voters. Here are the numbers of voters in the networks
random samples:
• Network A: 2250 voters sampled
• Network B: 2800 voters sampled
• Network C: 2500 voters sampled
Which sample is likely to have the least variability?
O
A. The Network A sample
OB. The Network B sample

C. The Network C sample

(3x-8) or (3x+8)

step-by-step explanation:

pretty sure 750 each month!

step-by-step explanation:

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
