Answer:
its the threed one.
Step-by-step explanation:
Given a data set consisting of 33 unique whole number observations, its five-number summary is: [19,32,47,61,77] how many observations are strictly less than 32?
Solution: The five number summary denotes:
Minimum = 19
First Quartile = 32
Median = 47
Third Quartile = 61
Maximum = 77
Since there are an odd number of observations (33) in the data set, the First Quartile (32) must be at the (33+1)/4 = 8.5th position, meaning there are 7 numbers less than 32.
Therefore, there are 7 observations that are strictly less than 32
More. 6x5/7=4 2/7 which is more than 5/7.
Answer:
C
Step-by-step explanation:
the distance is 15•6 = 18•5 = 90 feet
so, time needed = 90/30 = 3 second
