How do you find the mean or the range of a histogram?

The system of equations has infinite solutions.

Option D is correct.

Matrix multiplication is a binary operation whose output is also a matrix when two matrices are multiplied.

To multiply one matrix with another, we need to check first, if the number of columns of the first matrix is equal to the number of rows of the second matrix. Now multiply each element of the column of the first matrix with each element of rows of the second matrix and add them all.

Given

Matrix equations

[tex]\left[\begin{array}{ccc}2&4\\1&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}6\\3\end{array}\right][/tex]

L.H.S:

Using Matrix multiplication

[tex]\left[\begin{array}{ccc}2&4\\1&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}2x+4y\\x+2y\end{array}\right][/tex]

R.H.S:

[tex]\left[\begin{array}{ccc}6\\3\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}2x+4y\\x+2y\end{array}\right]=\left[\begin{array}{ccc}6\\3\end{array}\right][/tex]

Writing equation from above matrix

2x + 4y = 6

x + 2y = 3

or

2x + 4y = 6

2x + 4y = 6

Because there are two unknown number, but the two equations are consistent.

So, the system of equations has infinite solutions.

Option D is correct.

Answer:

w = 12°

Step-by-step explanation:

Angle J = Angle H

Angle K = Angle I

So lets find the sum of the entirety of angles

360° = 2w + 34° + 2w + 34° + 4w + 74° + 4w + 74°

360° = 12w + 68° + 148°

360° = 12w + 216°

Subtract 216° from both sides

360° - 216° = 12w + 216° - 216°

144° = 12w

Divide both sides by 12

144°/12 = 12w/12

12 = w

w = 12°

Using the similarity theorem of a triangle;

GH/FG = FG/EF

x/15 = 36/39

x/15 = 12/13

Cross multiply

13x = 12 * 15

13x = 180

x = 180/13

x = 13.85

Hence the value of x to the nearest hundredth is 13.85

Answer:

Solution given:

The length of the garden[l] = 2434 feet.

breadth or width [b]=b

perimeter of his garden = 7012 feet.

2[l+b]=7012ft

2434+b=7012/2

b=3506-2434

b=1072

So the width of the garden is 1072ft.

Answer:

A number multiplied by its self for ex 7 x 7 = 49 square root of 49 is 7

Answer:

A square root of a number is a value that, when multiplied by itself, gives the number. 6 · 6 = 36, so a square root of 36 is 6. You are probably curious why I said a square root and not the square root. - 6 · - 6 = 36. - 6 is a square root of 36. The symbol is √ which always means the positive square root.

√1 = 1

√4 = 2

√9 = 3

√16 = 4

√25 = 5

√36 = 6

√49 = 7

√64 = 8

√81 = 9

√100 = 10

Jack is wrong because he used the distributive property wrong. On the top equation, you see 2(4k - 3). The 2 multiplies into the (), so basically you have

2 x 4k - 2 x 3

which gives you

8k - 6

Answer:

Taniyah

Step-by-step explanation:

Taniyah is correct because you need to:

diistribute : 8k - 6 - 6k = 14

combine like terms : 2k - 6 = 14

add 6 to both sides : 2k - 6 + 6 = 14 + 6

simplify : 2k = 20

divide both sides by the same factor : 2k/2 = 20/2

simplify : k = 10

The missing values of the similar triangles is x = 20/3 and y = 4.5

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be ΔABC

Let the second triangle be ΔXYZ

Now , the corresponding sides are

15 / 10 = y / 3

Multiply by 3 on both sides , we get

y = 45 / 10

y = 4.5

Now , for the similar triangles , corresponding sides of similar triangles are in the same ratio

And , 2 / 3 = x / 10

Multiply by 10 on both sides , we get

x = 20/3

Hence , the similar triangles are solved
