UQ = 94
Step-by-step explanation:
This list is already sorted for you, so you don't need to worry about that, otherwise you would need to sort the numbers in ascending order. To find the median, we do , where n is the amount of numbers. This gives us 4, so the median is at position 4, so the median is 69. The lower quartile is simply
, so 2, so the lower quartile is 54. The upper quartile is

Recall that the repeating decimal 0.7373737373... can be written in fraction form as:
Now, let's write the number 147 which is inside the square root in factor form to find if it has some perfect square factors:
Then, 7 will be able to go outside the root when we compute the final product requested:
This is an irrational number due to the fact that it is the product of a rational number (quotient between 511 and 99) times the irrational number
