On a recent test, the ratio of Joe's mark to Ann's
mark to Maiseybelle's mark was 8:6:11. If Joe
got 72, what was the difference in the marks of
the other two?

The difference in the marks of Anna and Maiseybelle's was 45

Step-by-step explanation:

Let us use the ratio method to solve the problem

∵ The ratio of Joe's mark to Ann's  mark to Maiseybelle's mark

   was 8 : 6 : 11

∵ Joe got 72

By using the ratio method

→  Joe    :    Ann    :    Maiseybelle

→  8        :    6        :    11

→  72      :    x         :    y

By using cross multiplication

∵ 8 × x = 72 × 6

∴ 8 x = 432

- Divide both sides by 8

∴ x = 54

∵ 8 × y = 72 × 11

∴ 8 y = 792

- Divide both sides by 8

∴ y = 99

∵ x represents Ann's mark

∴ Ann got 54

∵ y represents Maiseybelle's mark

∴ Maiseybelle's got 99

Let us find the difference between Ann's mark and Maiseybelle's mark

∵ 99 - 54 = 45

∴ The difference between Ann's mark and Maiseybelle's mark is 45

The difference in the marks of Anna and Maiseybelle's was 45

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
