Find the lower quartile and upper quartile of the data set. 10, 11, 13,18,19,21,22,25,27,30,32

Answers

i believe the answer is 2

The lower quartile value is 13 and the upper quartile value is 27.

What is a Quartile?

A quartile divides the data set into four equal halves, that is, each set has an equal number of terms. The quartiles are given by Q₁(the lower quartile value), Q₂ (the median), Q₃ (the upper quartile value).

We first arrange the data set in ascending order. Here, the data set is already in ascending order, that is, 10,11,13,18,19,21,22,25,27,30,32.

So we will divide the above set into two equal halves. As the given set has 11 terms,

So the median is [tex]\frac{n+1}{2}[/tex] where n is the number of terms.

We have n=11

⇒ Median= [tex]\frac{11+1}{2}[/tex] th term

                = 6th term

⇒ Median= 21

Now the data to the left side of the median value will give the lower quartile and the data to the right will give the upper quartile.

The data to the left of median value 21 is 10,11,13,18,19.

The median value of this data will give the lower quartile value.

Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term

              =13

Lower quartile is 13.

The data to the right of the median value 21 is 22,25,27,30,32

The median value of this data will give the upper quartile value.

Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term

             = 27

Upper quartile is 27.

The correct answer is lower quartile= 13, upper quartile = 27

Find the rule that gives the number of dots needed to form the nth figure in each pattern.

Answers

Answer: adding a column and a row

Step-by-step explanation:

The rule which give the number of dots for the nth figure is [tex]= n^{2}[/tex]  or number of dots [tex]= n \times n[/tex], where n represents the number of figure.

What is pattern?

A pattern is a repeated arrangement of numbers, shapes, colors and so on.

Let n represents the number of figure and m be the number of dots.

According to the given question.

We have some figures which is made up of dots with following some patterns.

In the given first figure i.e. for n = 1

The total number of dots is 1.

[tex]\implies m = 1[/tex]

In the second figure i.e. for n = 2

The number of dots gets increased and the counts of dots are 4.

⇒ [tex]m = 4[/tex]

[tex]\implies m = 2 \times 2[/tex]

In the third figure i.e. for n = 3.

The number of dots are 9

[tex]\implies m = 9[/tex]

[tex]\implies m = 3 \times 3[/tex]

Similarly, for the nth figure, the number of dots is given by

[tex]m = n \times n[/tex]

[tex]\implies m = n^{2}[/tex]  

Hence, the rule which give the number of dots for the nth figure is number of dots [tex]= n^{2}[/tex]  or  number of dots [tex]= n \times n[/tex], where n represents the number of figure.

4.Solve for x: x + 1 + x + 4 + x - 2 = 90

Answers

Answer:

1. x = 86

2. x = 31

3. x = 64

4. x = 29

Step-by-step explanation:

1. 2x + 8 = 180

-8 -8

2x = 180 (divide both sides by 2 to get x by itself)

2. 3x - 3 = 90

+ 3 +3

3x = 93 (divide both sides by 3 to get x by itself. you divide because 3x is multiplying and you have to do the reverse operation)

3. 2x -5 + x - 7 = 180 (you combine like-terms)

3x -12 = 180

+12 +12

3x = 192 (you divide by 3 on both sides)

4. x + 1 + x + 4 + x - 2 = 90 (combine like-terms)

3x + 3 = 90

-3 -3

3x = 87 (divide both sides by 3)

Answer:

1) 2x + 8 = 180

Take 8 to the right side.

2x = 172

Divide both sides by 2.

x = 86

                                                                           

2) 3x - 3 = 90

Take -3 to the right side.

3x = 93

Divide both sides by 3.

x = 31

                                                                           

3) 2x - 5 + x - 7 = 180

Combine like terms.

3x - 12 = 180

Take -12 to right side.

3x = 192

Divide both sides by 3.

x = 64

                                                                             

4)  x + 1 + x + 4 + x - 2 = 90

Combine like terms

3x + 3 = 90

Take 3 to right side.

3x = 87

Divide both sides by 3.

x = 29

Answers

--Answer--

[tex]5\sqrt{2}[/tex] or 7.0710... (7.1)

--Explanation--

If you look closely the triangle on the left could be moved to the space on the right of the shape.

Then, the edges would be 10 inches (top) and 5 inches (sides).

From there, you multiply 10 x 5 to get 50. If you want the square root, you do [tex]\sqrt{50}[/tex] which is how I got 7.071067812, or 7.1, which was rounded to the nearest tenth.

Factor the quadratic x2+ 3x − 10. Explain your process for factoring and rewrite the original quadratic in factored form

Answers

Answer:

(x-2)(x+5)

Step-by-step explanation:

when factoring, our equation should be in this format: (x+__) (x+__) Then we have to find numbers that add up to 3 but multiply to -10 aka -2 and 5. -2+5=3 and -2(5)= -10

The first thing you must do is to find factors that equal to -10
1 x -10, -10 x 1, -2 x 5 and -5x 2. Then of these four groups of factor we chose the one that when the two factors are added equals to 3. So -2 x 5 equals 3
So are answer is
(x-2)(x+5)
