For the weight of the box that she measured, beatriz determined the margin of error as 23.5 pounds to 24.5 pounds. what was the greatest possible error for her actual measurement? 0.5 pounds 1 pound 24 pounds 24.5 pounds

Option A - 0.5 pounds

Step-by-step explanation:

Given : Beatriz determined the margin of error as 23.5 pounds to 24.5 pounds.

To find : What was the greatest possible error for her actual measurement?  

Solution :

To find the margin of error first we find the median of the given numbers.

Median of 23.5 and 24.5

So, the Greatest possible error is 24.5-24 = 0.5 pounds

Therefore, option A is correct.                                  

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
