Researchers report that children between the ages of 2 and 5 years watch an average of 25 hours of television per week. Assume that the variable time is distributed normally with a standard deviation of 2 hours. A random sample of 40 children between the ages of 2 and 5 was chosen. What is the probability that the average time of the selected group of 40 children between the ages of 2 and 5 watch more than 25.5 hours of television per week

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 is 11.2 (i know i’m late)

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
