In a bag there are pink buttons, yellow buttons and blue buttons. There are five times as many pink buttons as yellow buttons. number of yellow buttons : number of blue buttons = 4:7 One button is selected at random. Work out the probability that the button is either pink or blue. Give your answer as a fraction in its simplest form.​

39/59

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.
