The box plot represents a data set . what is the range of the middle 50% of the data?

3

Step-by-step explanation:

The middle 50% of the data is represented by the box.

The range is the difference between the upper value and the lower value

upper value = 7 and lower value = 4

Range = 7 - 4 = 3

3

Step-by-step explanation:

We know that the interquartile range is known as the range of the middle 50% of the data.

From the given box plot , the first quartile ( where box starts )

The third quartile  ( where box ends )

Then, the interquartile range =

Thus , the range of the middle 50% of the data =3

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:

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
