Total number of animals for which (p ∪ q) ∩ r is true is 15.

What is meant by union of sets?

The set that contains all the elements present in both sets is the union of the two supplied sets.

Here,

It is given that,

Set p is {2, 5, 8, 9}

Set q is {2, 4, 7, 5}

Set r is {2, 4, 6, 9}

The union of p and q, which includes all creatures that are in p, in q, or in both p and q, is known as p ∪ q.

p ∪ q = {2, 4, 5, 7, 8, 9}

The creatures that must be present in both (p and q) and r are contained in (p ∪ q) ∩ r.

So, (p ∪ q) ∩ r = {2, 4, 9}

Therefore,

2 + 4 + 9 = 15

Hence,

Total number of animals for which (p ∪ q) ∩ r is true is 15.

Answer:

x^2 - 3

Step-by-step explanation:

they both contain the variable of x^2 and -3 when factored out it would be

3 and x + 2

Answer:

x = -5

Step-by-step explanation:

− 6 x − 15 = 4 x + 35

Add 6x to each side

− 6 x+6x  − 15 = 4 x+6x + 35

-15 = 10x+35

Subtract 35 from each side

-15-35 = 10x+35-35

-50 = 10x

Divide each side by 10

-50/10 = 10x/10

-5 =x

Answer: x = -5

Step-by-step explanation:

In order to solve this problem, you need to isolate the variable.

In this problem, you need to isolate the x.

-6x -15 = 4x +35

10x = -50

x = -5

Answer: B) The mean will increase and the median will stay the same.

======================================================

Explanation:

Let's look at a small example of why this works.

Suppose that we had the set of 5 items {1,2,3,4,5}. The value 3 is right in the middle so this is the median. The mean is also 3 because adding all the values gets us 15 and then we divide over 5 (the number of items in the set) to get 15/5 = 3.

For any symmetric set of data like this, the mean and median are the same value.

Now let's change that last item 5 to something larger. Let's bump it up to 10

The new data set is {1,2,3,4,10}. The median is still 3 as it's still in the middle. But now the mean is (1+2+3+4+10)/5 = 20/5 = 4. The old mean was 3, and the new mean is 4. So we have the mean increased thanks to that 5 increasing to 10.

We could increase 10 to 20 getting {1,2,3,4,20}. The median is still the same. The mean is now (1+2+3+4+20)/5 = 30/5 = 6. So we've increased the mean again. This process can be continued on for as long as you like.

The outliers to the right hand side effectively pull on the mean in a similar analogy to how gravity pulls on an object. So this is one way to remember that the mean is effected by outliers. The median only cares about being in the middle so that's why it doesn't change. If we changed the number of items in the data set, then it's a different story. However, Kay is only changing her salary rather than bring on a new hire (or two).

So that small example can be applied to Kay's situation even though the numbers are much larger. The median stays the same, but Kay's (much) higher salary pulls on the mean to make it larger than it should be. This is often why a trimmed mean is used when looking at centers of data sets. For data sets that have very large outliers, the median is the more reliable measure of center.

Answer:

Step-by-step explanation:

Given two coordinates (x₁,x₂) and (y₁,y₂), their midpoint (w,y) is expressed as:

M(X,Y) = [tex](\dfrac{x_1+w}{2}, \dfrac{y_1+y}{2})[/tex]

From the question, we are given the midpoint (X,Y) to be (2,2) and one endpoint as (1, -2) and we are to find the other end point expressed as (w,y). From the coordinates given, i can be seen that X = 2, Y =2, x₁ = 1 and y₁ = -2

Substituting the given end points into the given formula to get the other end points, we will have;

[tex]X = \dfrac{x_1+w}{2} \\2 = \dfrac{1+w}{2} \\cross\ multiply\\4 = 1+w\\w = 4-1\\w = 3[/tex]

Similarly;

[tex]Y = \dfrac{y_1+y}{2} \\2 = \dfrac{-2+y}{2} \\cross\ multiply\\4 = -2+y\\y = 4+2\\y = 6[/tex]

Hence the other endpoint (w, y) is (3,6)

Answer:

Star B

Step-by-step explanation:

If Star A is 5.23*10^7 light years away from earth, and star B is 7.1*10^5 light years away from earth, then the closest Star to earth is Star B.

this is because a light year is 9.461*10^15 m away, if we multiply this, then Star A is 4.948*10^23 m away from earth, and Star B is 6.717*10^21 m away from earth, and this makes it closer when compared to Star A.

Holly is incorrect. The decimal part follows a pattern but does not actually repeat.

so D is the correct option

Step-by-step explanation:

The numbers follow a pattern but if you take a closer look you will see that the numbers do not repeat even though they still use the numbers 1, and 3 doesn't mean there a rational number.

Holly is incorrect. The decimal part follows a pattern but does not actually repeat.

The numbers follow a pattern but if you take a closer look you will see that the numbers do not repeat even though they still use the numbers 1, and 3 doesn't mean there is a rational number.

If the value of a numerical expression is terminating then they are the rational number then they are called the rational number and if the value of a numerical expression is non-terminating then they are called an irrational number.

Hence, the decimal part follows a pattern but does not actually repeat.

Answer:

m = 21 - 72·i in an ordered pair =  (21, -72)

Step-by-step explanation:

Graphing complex numbers involves the application of the methodology of graphing real numbers on the coordinate plane in addition to the Argand coordinate plane to form the complex coordinate plane, such that where the complex number is of the form a + bi, the real part of the complex number, a, is taken as the x-coordinate value while the imaginary part, b, is taken as the y-coordinate value

As such to represent the complex number as an ordered pair, we have;

a + bi is equivalent to (a, b)

Therefore;

To write the complex number, m = 21 - 72·i as an ordered  pair in an Argand diagram, we have;

m = 21 - 72·i in an ordered pair =  (21, -72).

This is immediately proven false by irrational numbers: real numbers that are not rational. Examples include π or √2.

II) Zero is an integer number.

This is true. Integers include the set of whole numbers, which includes 0.

III) All counting numbers are whole numbers.

This is true. Whole numbers (0,1,2,3...) is basically the counting numbers (1,2,3,...) but with 0.

IV) Irrational Numbers are not real numbers.

This is false. Real numbers can be divided into two subsets: irrational and rational.

Answer:

Additional 26 pendants are to be sold to make profit.

Step-by-step explanation:

Rent of booth at the craft fair = $200

Cost of material for each pendant = $7.80

Let Kelsey makes [tex]x[/tex] number of pendants.

To calculate the total spending, we have to add the rent of booth at the craft fair and cost of material for [tex]x[/tex] number of pendants.

Cost of material for [tex]x[/tex] number of pendants = Cost of material for each pendant multiplied by number of pendants

Cost of material for [tex]x[/tex] number of pendants = $7.80 [tex]\times[/tex] [tex]x[/tex]

So, total cost = $200 +  $7.80 [tex]\times[/tex] [tex]x[/tex]

Now, each pendant is sold at $13.50

So, total money made by selling  [tex]x[/tex] pendants =  $13.50 [tex]\times[/tex] [tex]x[/tex]

For making profit, total money made must be greater than the total cost.

Therefore, the inequality becomes:

[tex]\bold{13.50 \times x > 200+7.80\times x }[/tex]

Let us solve the inequality now:

[tex]13.50x - 7.80x>200\\\Rightarrow 5.7x > 200\\\Rightarrow \bold{x > 35.08}[/tex]

So, at least 36 pendants are to be sold to make a profit.

Additional 36-10  = 26 pendants are to be sold to make profit.
