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

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}

The multiplication of the expressions 2i and (4 – 5i) is 10 + 8i. Then the correct option is D.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The expressions are 2i and (4 – 5i).

Then the product of the expression will be given as

2i (4 – 5i)

8i – 10i²

And we know that i² = -1

Then we have

8i – 10 (–1)

10 + 8i

Hi!

One yard is equal to 3 feet.

Therefore, we can simply divide the number of feet by 3 to get the number of yards.

First, let's convert 9 feet into yards.

9/3 = 3 yards

So, we know that 3 yards of cotton cloth cost $15.84

To get the price per yard, we want to divide the number by 3, as there are 3 yards total.

We will get the price per yard by doing that.

15.84 / 3 = 5.28

Therefore, the price per yard is $5.28.

Answer: $5.28 per yard

Step-by-step explanation:

   There are 3 feet in one yard. We can divide 9 by 3 to see how many yards the price given is for.

       9 / 3 = 3

       This piece of cotton cloth is 3 yards. To find the price of one yard, we will divide the cost given by 3.

$15.84 / 3 = $5.28 per yard

         The price per yard is $5.28.

Answer:

Equation: [tex]\frac{36+x}{2} =65[/tex]

x = 94

Step-by-step explanation:

First, take the values and plug them into our general formula used in relationships between interior and exterior angles.

[tex]\frac{36+x}{2} =65[/tex]

Now, rearrange the equation to get x by itself. This will eventually lead you to the answer sought.

[tex]36+x=65*2 = 130\\x =130-36 = 94\\x = 94[/tex]

[tex]y = \cfrac{2}{3}x~~ - ~~6~\hspace{10em} (\stackrel{x}{?}~~,~~\stackrel{y}{0}) \\\\\\ 0=\cfrac{2}{3}x~~ - ~~6\implies 6=\cfrac{2x}{3}\implies 18=2x\implies \cfrac{18}{2}=x\implies 9=x[/tex]

Answer:

y=-2x+6

Step-by-step explanation:

So you know the perpendicular gradient is -2 so the equation so far is y=-2x+?

Find the midpoint of AB which is:

(3,0)

Using this, plug it into the equation you've formed:

0= -6 + ?

? = 6

So the equation of the perpendicular line is y=-2x+6

The mean height decreases because of the outlier, The median stays the same and the range increases because of the outlier.

Outlier in a data set is simply the extremely low data point or an extremely high data point compared to other points in the dataset.

It will stand out from the other values in the dataset.

Given a dot plot which represents the height in inches of the Deep Purple Gymnastics Team members.

Only mean and range is affected by the outlier, median will not, since the middle value of the data set remains the same even if the end values are changed.

Here outlier is at the lowest end, which is 60.

Mean is the average of the data points. Since the outlier is at the low end, mean decreases.

Median stays the same.

Range is the difference of maximum and the minimum value. Range increases since the minimum value is lower.

Hence the mean decreases, median stays the same and range increases.
