The manager where you work has made a contest to encourage you to learn more about a new company you are working with for business. every time you get a correct answer to the manager's question, you get to draw a $1, $5, or $10 bill from a bag. there are 10 bills in the bag. 5 are $1 bills, 4 are $5 bills, and 1 is a $10 bill. if you are the first to draw, what is your expected value in rewards?
a. $6.00 b. $6.25 c. $5.50 d. $6.50]

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

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:

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
