Abag contains 15 balls of which some are white and some are black the probability of drawing a black ball is 2 by 3 so find the number of white balls in the back

probability of black ball is 2/3 .

so number of black ball is given as = total ball × prob of black ball

= 15×2/3 = 5×2 = 10

so black balls are 10

so white balls are = 15 - 10 = 5

answer: asdfghjkl,mnbv

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.
