Answer:
The first step is sort the values on increasing order and we got:
18, 18, 19, 19, 19, 20, 22, 23. 25, 26, 31
And in order to find the first quartile we can separate the first 5 lowest values from the largest 5 values. And for this case we focus on these values:
18, 18, 19, 19, 19
And if we find the median of the last 5 values we can find the first quartile and we got:
The best answer would be:
19
Step-by-step explanation:
For this problem we have the following dataset:
18, 26, 19, 25, 19, 23, 31, 22, 19, 18, 20

Answer:
The number is 86
Step-by-step explanation:
Let the number be , then the reverse is
The sum of the reversed number and the original number is 154,
We simplify this to get:
....eqn(1)
If the ones digit in it is 2 less than the tens digit, then
....eqn(2)
Putt equation (2) in (1)
Put x=8 in the second equation:
The original number is 86
