Mrs. little creates a boxplot for the test scores on her latest math test. she finds that the interquartile range is 20 points. what does this mean? a) that the median number of points off was 10. b) that half the students scored 20 points higher. c) that the highest grade was 20 points above the median. d) that the middle 50% of the scores were 20 points apart.

D) That the middle 50% of the scores were 20 points apart.

Step-by-step explanation:

Interquartile range measures the skewness using 50% of the data. It is the difference between the third quartile and the first quartile.

A) this option is incorrect as it does not define the Interquartile range.

B) No, it is the definition of median.

C) No, it does not define the interquartile range.

D) Yes, it is correct answer.

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
