Step-by-step explanation:

By Geometric mean property:

${y}^{2} = 4 \times 12 \\ \therefore \: {y}^{2} = 48 \\ \therefore \: {y} = \sqrt{48} \\ \therefore \: {y} = \sqrt{16 \times 3} \\ \huge \red{ \boxed {\therefore \: {y} = 4\sqrt{3} }}$

Thus, option A) 4√3 is the correct answer.

The elements of Matrix C are shown below.

sergeinik [125]

The matrix that represents the matrix D is $\left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

<h3>How to determine the matrix d?</h3>

Given the elements of the matrix C.

The matrix c is represented by its rows and columns element, and the arrangements are:

C11 = 3 C12 = 1 C13=-9 C14 = 8

C21 = 2 C22=2 C23 =0 C24 = 5

C31 = 16 C32 = 1 C33=-3 C34=11

Remove the matrix name and position

3 1 9 8

2 2 0 5

16 1 -3 11

Represent properly as a matrix:

$C = \left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

Matrix C equals matrix D.

So, we have:

$D = \left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

Hence, the matrix that represents matrix D is $\left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

The dual bar chart shows the hair colour of boys and girls in a year group.

Natasha2012 [34]

The fraction of the red haired students are boys will be 2 / 5.

<h3>What is a fraction number?</h3>

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.

The dual bar chart shows the hair colour of boys and girls in a year group.

The total number of the boys and girl will be

Total = 6 + 9

Total = 15

Then the fraction of the red haired students are boys will be

⇒ 6 / 15

⇒ 2 / 5
