How do you survive when there's no time to eat - fast food, no food, a protein bar, candy? A Snapshot in USA Today indicates that 36% of women aged 25-55 say that, when they are too busy to eat, they get fast food from a drive-thru. A random sample of 100 women aged 25-55 is selected. A. What is the average number of women who say they eat fast food when they're too busy to eat? B. What is the standard deviation for the number of women who say they eat fast food when they're too busy to eat? C. If 49 of the women in the sample said they eat fast food when they're too busy to eat, would this be an unusual occurrence? Explain.

step-by-step explanation:

a. she will receive a refund of $278.

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

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.
