The formula of area of square.

means

Area = 4

a^2

4^2

4x4 = 16

Explanation

To find the volume of a rectangular box, we use the formula:

Volume=Length×Width×Height

Given the dimensions of the box:

Length (𝐿) = 10 cm

Width (𝑊) = 15 cm

Height (𝐻) = 20 cm

Plug these values into the formula:

Volume=10cm×15cm×20cm

Volume=10×15×20

Volume=150×20

Volume = 3000cm^3

So, the volume of the rectangular box is 3000cm^3

 .

Explanation

The transpose of a square matrix is also a square matrix.

The transpose of a matrix is obtained by swapping its rows with its columns, and this operation preserves the square shape of the matrix.

Explanation

A confidence level of 95% corresponds to a significance level of 0.05.

The significance level, often denoted by alpha (α), is the probability of rejecting the null hypothesis when it is true.

 It is the complement of the confidence level.

 Therefore, if the confidence level is 95%, the significance level would be

1- 0.95 = 0.05

A circle is a perfectly round shape with all points equidistant from its center.

It creating a continuous curved boundary.

Explanation

54 m²

∴ The area of the four walls of the room is 54 m².

Think of the floor as a square. Suppose the  wall is 20 feet long. Multiply 20  by 4 to get a circumference of 80 feet. Double the width and length measurements and add them  to calculate the perimeter of the rectangular room.

Explanation

Now let's evaluate the options:

(A) ab: This string matches $ab^*$ (since $b^*$ allows for one 'b'). So, this belongs to $\mathrm{R<b\; style="color:\; rgb(0,\; 0,\; 0);\; font-family:\; Overpass,\; sans-serif;\; font-size:\; 0.875rem;"><br></b>}$

(B) abb: This string also matches ab∗ (since $b^*$ allows for two 'b's). So, this belongs to $R$.

(C) cb: This string matches cb∗ (since $b^*$ allows for one 'b'). So, this belongs to $R$.

(D) All of these: Since all the previous options (A, B, C) belong to $R$, this is correct.
