Find the median of the following numbers: 195, 230, 200, 226​
BlackZzzverrR [31]

Answer: 213

Step-by-step explanation: The median is the middle number

in the data set when the data set is written from least to greatest.

So let's start with writing ur data set from least to greatest.

So we have 195, 200, 226, 230.

Notice that there are two middle numbers.

If there are two middle numbers in the data set,

we find the median by taking their average.

In other words, we add the two middle numbers and divide by two.

So we have 200 + 226/2 or 426/2 which is 213.

Define each following sets by listing its elements, the set of letters in the word "salt"
leonid [27]

The word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}

<h3>What is set?</h3>

A set is a collection of clearly - defined unique items. The term "well-defined" applies to a property that makes it simple to establish whether an entity actually belongs to a set. The term 'unique' denotes that all the objects in a set must be different.

We have given letter:

"salt"

Here, no letter is repeated.

So we can write it as roaster form:

Let's denote the set as S

S = {s, a, l, t}

Number of element in the set = 4

We can make new set from it if the set has only vowels

S(v) = {a}

If set has only consonants:

S(c) = {a, l, t}

Thus, the word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}
