165/300 -> 55%
This doesn't make much sense though, either the question is out of context or there is some typo because empirical probability is based on results you get from an experiment and actually doing the trial, not on what happens mathematically

I don’t know if there is an outlier or not how can you tell
SIZIF [17.4K]
To find an outlier, multiply the IQR by 1.5

172,500 * 1.5 = 258,750

now, u add that to Q3.....545,000 + 258,750 = 803,750....anything above this number is an outlier

now,u subtract that from Q1....372,500 - 258,750 = 113,750....anything below that is an outlier

u have already done this...u have found the higher end and the lower end....so anyting larger then the higher end or lower then the lower end is ur outlier

so in ur data, there is only 1 outlier and that is 933.....130 is not an outlier because it is not less then 113,750.

The length of the hypotenuse of a right triangle is 24. If the length of one leg is 8, what is approximate length of the other l
Verdich [7]

Something that a right triangle is characterised by is the fact that we may use Pythagoras' theorem to find the length of any one of its sides, given that we know the length of the other two sides. Here, we know the length of the hypotenuse and one other side, therefor we can easily use the theorem to solve for the remaining side.

Now, Pythagoras' Theorem is defined as follows:

c^2 = a^2 + b^2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

Given that we know that c = 24 and a = 8, we can find b by substituting c and a into the formula we defined above:

c^2 = a^2 + b^2

24^2 = 8^2 + b^2 (Substitute c = 24 and a = 8)

b^2 = 24^2 - 8^2 (Subtract 8^2 from both sides)

b = √(24^2 - 8^2) (Take the square root of both sides)

b = √512 (Evaluate 24^2 - 8^2)

b = 16√2 (Simplify √512)

= 22.627 (to three decimal places)

I wasn't sure about whether by 'approximate length' you meant for the length to be rounded to a certain number of decimal places or whether you were meant to do more of an estimate based on your knowledge of surds and powers. If you need any more clarification however don't hesitate to comment below.
