Which of the following is false? A) A measure of center alone does not completely describe the characteristics of a set of data. Some measure of spread is also needed. B) If the original measurements are in inches, converting them to centimeters will not change the mean or standard deviation. C) One of the disadvantages of a histogram is that it doesn’t show each data value. D) Between the range and the interquartile range, the IQR is a better measure of spread if there are outliers. E) If a distribution is skewed, the median and interquartile range should be reported rather than the mean and standard deviation.

step-by-step explanation:

it's 15

the answer is (-4,-4)

hope this ! : d

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.
