An epidemiologist plans to conduct a survey to find out what percentage of women give birth. How many women must be surveyed in order to be 99% confident that the estimated percentage is in error by no more than two percentage points

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

the answer will be b x² +x-1

step-by-step explanation:

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2
