Answer:
r = -
Step-by-step explanation:
Given that r varies inversely as t , then the equation relating them is
r = ← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = ( multiply both sides by - 6 )
12 = k, thus
r = ← equation of variation
when t = - 7, then
r = = -
Answer: The third quartile of the distribution is 23.
Step-by-step explanation:
First we write the data in ascending order:
4,5,8,10, 11,11, 13,15,16, 18, 18, 18, 21, 23, 24, 24, 25, 27, 31, 32
Since there are 20 terms:
First half is for First Quartile :
4,5,8,10, 11,11, 13,15,16, 18
Second half is for third Quartile:
18, 18, 21, 23, 24, 24, 25, 27, 31, 32.
So, Value of third quartile would be
Hence, the third quartile of the distribution is 23.
