Answer:
81.2 is the 62th percentile
Step-by-step explanation:
What is the interpretation for a percentile?
When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.
300 observations, there are 186 points less than 81.2. Find the percentile for 81.2.
So

81.2 is the 62th percentile
33 1/3% is the same thing as 0.3 repeated or typically 0.33, and as a fraction it is equivalent to 1/3.
15x+100=28
x=-6/5
The answer is -6/5
It would be 3 cm by 4 cm because you just divide the number of feet by 4.
