If the median of a list of numbers is m, the first quartile of the list is the median of the numbers in the list that are less than m. what is the first quartile of the list of numbers 42, 24, 30, 22, 26, 19, 33 and 35 ? a) 33b) 28c) 27d) 24e) 23

First  quartile  list of number median is 23

Step-by-step explanation:

List of numbers = 42,24, 30 , 22 , 26, 19, 33, 35

Arrange them in a sequence:

List of numbers = 19, 22, 24, 26, 30, 33, 35, 42

The median of {19, 22, 24, 26, 30, 33, 35, 42} is= 26+30/2 = 28

Numbers that are less than the median are { 19 , 22 , 24 , 26}

then

median of the list = 22+24/2 = 23

So the first  quartile  list of number median is 23.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
