The median for a set of numbers would be the one that appears closest to the middle of the set.
For the set 4, 8, 10, 5, 9, in order to find the median, we must first sort them numerically.
4, 5, 8, 9, 10
Now, which of these 5 numbers is the closest to the middle?
The answer to that would be 8, since it is actually the number in the middle.
The median number for the numbers 4, 8, 10, 5, 9 is 8.
Hope that helped =)
Answer:
isn't an equivalence relation. It is reflexive but neither symmetric nor transitive.
Step-by-step explanation:
Let denote a set of elements. would denote the set of all ordered pairs of elements of .
For example, with , and are both members of . However, because the pairs are ordered.
A relation on is a subset of . For any two elements, if and only if the ordered pair is in .
A relation on set is an equivalence relation if it satisfies the following:
- Reflexivity: for any , the relation needs to ensure that (that is: .)
- Symmetry: for any , if and only if . In other words, either both and are in , or neither is in .
- Transitivity: for any , if and , then . In other words, if and are both in , then also needs to be in .
The relation (on ) in this question is indeed reflexive. , , and (one pair for each element of ) are all elements of .
isn't symmetric. but (the pairs in are all ordered.) In other words, isn't equivalent to under even though .
Neither is transitive. and . However, . In other words, under relation , and does not imply .
Answer:
5x^2+x-6
Step-by-step explanation:
(5x-1)(x+1)-5x+x-5+x
(5x^2+5x-x-1)-5x+x-5+x
5x^2+x-6

The computation shows that the average monthly amount is 61.64.
<h3>How to calculate the value?</h3>
The amount that's left will be:
= 3314.85 + (2 × 926.65) - (1800 × 2) - 1075
= 3314.85 + 1853.3 - 3600 - 1075
= 493.15
The average monthly amount will be:
= 493.15/8
= $61.64
