27, 36, 45...all have factors of 9 and r greater then 20
Step-by-step explanation:
We are told that for a large data set of a average student grades, the third quartile Q3 is found 78.5.
Since we know that third quartile represents the number such that 75% of the data is less than this number. Third quartile is the middle value between median and the highest value of a data set. Third quartile is also known as upper quartile. Third quartile splits lower 75% data from highest 25% of data.
Therefore, third quartile represents that 75% of student grades are less than 78.5 and 25% of students grades are greater than 78.5.
Answer:
5 5/8
Step-by-step explanation:
9 = 9/1
so 9 x 5/8 = 9/1 x 5/8
you could quickly make it 45/8 or make it 9x5/1x8
45/8 is improper so you have to see which multiple of 8 is the highest without exceeding the numerator
40 is the closest and it is 8x5 so 5 will be the integer.
there are 5 leftover so 5 is also the numerator
and the denominator stays 8 as there is no further simplifying
so, the answer is 5 5/8
