A bag contains 3 white balls, 4 green balls, and 5 red balls. A ball is drawn at random. How many total number of outcomes are there?

12.

Step-by-step explanation:

Given that,

Number of while balls are 3

Number of green balls are 4

Number of red balls are 5

We need to find the total number of outcomes. We know the total number of outcomes in is number of choices.

In this case, total number of outcomes are the sum of all color balls i.e. 3 + 4 + 5 = 12 balls.

Hence, the total number of outcomes are 12.

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.
