The weight of an organ in adult males has a bell-shaped distribution with a mean of 330 grams and a standard deviation of 40 grams. Use the empirical rule to determine the following. (a) About 95% of organs will be between what weights?
(b) What percentage of organs weighs between 290 grams and 370 grams?
(c) What percentage organs weighs less than 290 grams or more than 370 grams?
(d) What percentage of organs weighs between 290 grams and 450 grams?

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:

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
