D. 20, 20, 21, 22, 22

Answer:

A. 18, 20, 20, 22, 25

Step-by-step explanation:

Required

Which list has a mean of 21 and median of 20

Each of the list have 5 numbers and they've all been sorted.

The median is the number at the 3rd position (i.e. the middle number)

So, list C and D are out because they do not have a median of 20.

Next, calculate the mean of lists A and B

[tex]\bar x = \frac{\sum x}{n}[/tex]

A. 18, 20, 20, 22, 25

[tex]\bar x = \frac{18 + 20 + 20 + 22 + 25}{5}[/tex]

[tex]\bar x = \frac{105}{5}[/tex]

[tex]\bar x = 21[/tex]

B. 20, 20, 20, 25, 25

 [tex]\bar x = \frac{20 + 20 + 20 + 25 + 25}{5}[/tex]

[tex]\bar x = \frac{110}{5}[/tex]

[tex]\bar x = 22[/tex]

Only list A has a median value of 20 and a mean value of 21

Answer:

The A matches the table x+3

10.) 1/13

Answer:

If you begin with the graph for f(x) and then substituted x+3 for x, the effect on the graph will be to move the whole graph 3 units to the left.  

Given that (-9,-1) is on the graph of f(x), and that we are to move the entire graph 3 units to the left, then the coordinate -9 becomes -9-3, or -12:  (-12,-1).

The question is incomplete. The complete question is :

A 15-meter by 23-meter garden is divided into two sections. Two sidewalks run along the diagonal of the square section and along the diagonal of the smaller rectangular section. What is the approximate sum of the lengths of the two sidewalks, shown as dotted lines? 21.2 m 27.5 m 32.5 m 38.2 m

Solution :

From the figure, we apply the Pythagoras theorem.

Finding the lengths of the two side walks :

1st Step

In the square section,

The length of the diagonal is given by :

[tex]$D=\sqrt{15^2+15^2}$[/tex]

    [tex]$=\sqrt{450}$[/tex]

   = 21.21 m

2nd step

In the rectangular section,

The length of the diagonal is given by :

[tex]$D=\sqrt{15^2+8^2}$[/tex]

    [tex]$=\sqrt{289}$[/tex]

   = 17 m

3rd step

Therefore, the total length of the two diagonals of the two section is

 =  17 + 21.21

 = 38.21 m

or 38.2 m

Answer: it's D (38.2nm)

Answer:

7 people

Step-by-step explanation:

Chocolate: 350 / 100 = 3.5 x 2 = 7

Butter: 45 / 10 = 4.5 x 2 = 9

Eggs: 8 / 2 = 4 x 2 = 8

The amount of chocolate is the limiting factor as you have enough eggs for 8 people and enough butter for 9 people, but only enough chocolate for 7 people

Answer:

I believe the answer is 2/3

Step-by-step explanation:

Answer: 3,3

Step-by-step explanation:

Answer:

The ratio of perimeter of ABCD to perimeter of WXYZ = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

First, we have to determine the multiplicative factor of the dimensions for both figures.

Considering sides AB and WX,

multiplicative factor = [tex]\frac{12}{8}[/tex]

                                = 1.5

So that:

XY = 6 x 1.5 = 9

YZ = 7 x 1.5 = 10.5

ZW = 7 x 1.5 = 10.5

Perimeter of ABCD = 6 + 7 + 7 + 8

                                = 28

Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12

                                 = 42

The ratio of the perimeters of the two quadrilaterals can be determined as;

ratio = [tex]\frac{perimeter of ABCD}{Perirmeter of WXYZ}[/tex]

       = [tex]\frac{28}{42}[/tex]

       = [tex]\frac{2}{3}[/tex]

The ratio of the perimeter of ABCD to perimeter of WXYZ is [tex]\frac{2}{3}[/tex].

Answer:

Step-by-step explanation:

8/2 = 4:1 cause 2 can go into 8, 4 times.

For negative 8

1. -4 x 2

2. -48 ÷ 8

For negative 15

1. -5 x 3

2. -60 ÷ 4

Answer:

x = 4

Step-by-step explanation:

Given

[tex]\frac{x-2}{4}[/tex] = [tex]\frac{3x-7}{10}[/tex] ( cross- multiply )

4(3x - 7) = 10(x - 2) ← distribute parenthesis on both sides )

12x - 28 = 10x - 20 ( subtract 10x from both sides )

2x - 28 = - 20 ( add 28 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Answer:

113.04

Step-by-step explanation:

Surface area for a sphere is 4*pi*radius^2

4*3*3*3.14

113.04

The surface area of the sphere with the given radius is 113.04cm².

A sphere is simply a 3-dimensional object with no vertices and edges.

The surface area of a sphere is expressed as;

Area = 4πr²

Given the data in the question;

To determine the surface area of the sphere, we substitute our given values into the expression above.

Area = 4πr²

Area = 4 × 3.14 × (3cm)²

Area = 4 × 3.14 × 9cm²

Area = 113.04cm²

Therefore, the surface area of the sphere with the given radius is 113.04cm².

I hope this helps :)

lets take number one for example,

When subtracting negative numbers, the (-) in the number (-20) cancels out the original minus sign, therefore, to answer the equation:

10 - (-20)

you would need to turn the equation into an addition problem, getting the equation:

10 + 20

and from there you can get the simple answer of:

30
