What is Modulus Function?

Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.

It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:

Given data ,

Let the number be x

x = |3|

Now , the opposite of the number x = -x

So ,

The opposite of |x| = -|x|

And ,

The opposite of |3| = - |3|

Hence , The opposite of |3| = - |3|

The area of the rectangle can be expressed as [tex](\frac{6x}{5})^2[/tex].

What is the area of the rectangle?

If the length of the rectangle is 'l' and the breadth of the rectangle is 'b', then the area of the rectangle can be computed as

                   Area = l * b

Given data:

        The width of the rectangle is 3x/5 cm.

   And its length is four times its width so length = 4 * 3x/5

                                                                                 = 12x/5 cm.

Then the area will be

              Area = length * breadth

                       = 12x/5 * 3x/5

                       = 36x²/25

Here in the rhombus ABCD the value of y is 7.5.

A rhombus is a unique kind of quadrilateral with four equal sides and perpendicular diagonals that cut the angles and one another in half.

So here 4x+15 = 7x+2 and

12y = 90.

To find the remaining values by first solving for each variable, then substituting as necessary.

4x+15=7x+2

15=3x+2

13=3x

13/3 = x

BC is 4x+15

= 4(13/3)+15

= 52/3 + 45/3

= 97/3

CD is 7x+2

= 7(13/3)+2

= 91/3 + 6/3 = 97/3

Then, find 12y=90 and y=7.5.

AFB is a 90° angle (12(7.5)).

BCF is a 4y-1 = 4(7.5)-1 = 29 angle.

Because the diagonal cuts the angle in half, angle BCD is equal to 58. Angle ABC thus becomes 180-58 = 122.

Therefore the value  of  y  is 7.5 .

The number of rotations will be the ratio of the total distance traveled to the distance traveled in one rotation thus the total rotation to cover 20 feet will be 7.64.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

The longest line which can be drawn inside the circle will be the diameter.

The number of rotations will be the ratio of the total distance traveled to the distance traveled in one rotation.

Distance traveled in one rotation = Perimeter of the wheel.

⇒ 2π(5) = 31.42 inches

The number of rotations = (20×12)/31.42 = 7.63

The two ways of forming isosceles triangle by bending the metal strip using length by length by base are

A triangle that have the two sides equal is referred to as an isosceles triangle.

Using a strip of 20 inches long to construct an isosceles triangle means that the perimeter of the triangle is 20 inches

the perimeter is equal to base + length + length

bending 6 inches already means one of the dimensions is gotten then fo the other is based on if

if the 6 is base then minus the 6 from 20 and divide the rest for the length

20 - 6 = 14

the two lengths is 14 one length is 7. so we have 6 + 7 + 7 = 20

If the 6 is length then get another 6 and the rest is base

20 - 6 = 14

14 - 6 = 8

therefore we have 6 + 6 +8 = 20 inches

The relative percentages of the column-wise frequencies are different, indicating that there is indeed an association between the variables.

A user-defined collection of related groups and items is referred to as a data association. It may include one or more groupings, as well as some, all, or neither of the items found inside those groups. It is helpful to initially identify various groups and components that you believe to be connected in some way before establishing Rules of Visibility.

Because of the differences in the relative percentages of the column-wise frequencies, there is a link between the variables. The animal mascot in the first column has 74% victories and 26% defeats.

The meaning of the c-value when T=65 is:  The number of times the cricket could be expected to chirp in one minute if it's 65 degrees F

The correct answer is an option (D)

In this question, we have been given a linear relationship.

For a certain type of cricket, this relationship can be expressed using the formula T=34+0.3c,

where T represents the temperature in degrees Fahrenheit and

c represents the number of times the cricket chirps in one minute.

We need to interpret the value of c when T = 65.

T = 34 + 0.3c

65 = 34 + 0.3c

c = 103.33

c = 103.33 represents the number of times the cricket could be expected to chirp in one minute if it's 65 degrees F

12.5 72

Step-by-step explanation:

Because shows that the basketball player wear size 11.5 73 inches tall so basically the answer would be 12.5 72

The equation of the regression line is y = 0.77x + 61.95. The residual is 2.2 inches. The residual means that the gap between the estimated and anticipated values is 2.2 inches.

A regression line shows a linear connection between the y-dependent axis's variables and the x-independent axis's variables. The connection is determined by examining the data pattern created by the variables.

From the table, the points are given as follows:

(7, 64.5), (10, 70), (12.5, 72), (8.5, 71), (9, 69), (10, 70), (11, 75), (12.5, 69), (13, 71), (10.5, 68).

Inserting these points into the linear regression calculator, the equation is given as follows:

y = 0.77x + 61.95 ...(i)

For a shoe size of 11.5 inches, the predicted height is given as below:

y = 0.77(11.5) + 61.95 = 70.8 inches.

The residual is the gap between the estimated and anticipated values, hence:

Residual = 73 inches - 70.8 inches = 2.2 inches.
