What is the first quartile of the following data set? 12, 33, 15, 22, 29, 11, 17, 19, 10, 24, 38

First, organize the numbers in numerical order:
10, 11, 12, 15, 17, 19, 22, 24, 29, 38
Then, find the mean: which is the middle of the data set. The middle lies right between 17 and 19, which is 18.
The first quartile is the middle of the first half. Which is the number 12.
So remember how you can factor out ones
like (4/8)=(4/4)(1/2)=(1)(1/2)
so first factor each think see if we can simplify any of them
can't
ok so remember division of fractions
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
invert and multiply
so
=
=
=
=
=

The slope is 2 because if you put the change in y over the change in x you get 2/1 and the 1 on the bottom don’t make a difference so it’s just 2
You multiply the two numbers and divide by 2

Answers:
- A) Definition of right angles
- B) Substitution
- C) Definition of congruence
=========================================
Explanation:
- A) The term "right angle" is another way of saying "90 degree angle". This is a definition. Think of a definition in a dictionary.
- B) The substitution property allows us to replace one thing for another, as long as the two things are equal. The transitive property works as a similar idea.
- C) If two angles have the same measure, then they are congruent. This is the definition of congruence (or one form of it).
