One way to write 18/6 is to compute 18/6 to be the whole number of a quotient that is equal to. Another way to write 18/6 is to write it as an improper fraction that's reduced. One more way to write 18/6 is as a decimal. Note how all of these ways of writing the same expression are all equal to writing one same value, and it's the WAY in which you modify what you're writing.
Answer:
18.75%
Step-by-step explanation:
Altogether he took 16 tests he failed 3 so we need to find 3 is what percent of 16.
Let us calculate the median; the 6th observation is 20, so it is 20. We need the 6th observation so that out of the 11 observations we have 5 above the median and 5 below (or equal). We also have that then Q1 is the median of the lowest 5 observations, hence 19 (14,16,19,19,20, the 3rd observation is 19). Similarly, we get that the median for the upper half of the observations, Q3 namely, is 22 (21,21,22,22,23, the 3rd observation is 22). Thus, the interquartile range is 3=Q3-Q1. According to our calculations, all observations are wrong.
