A school principal has to choose randomly among the six best students in each grade to be the school captain every month. For that purpose, she assigned each student a number. Then she rolled two dice numbered from 1 to 6 three times and selected the student whose number was repeated most often.

Which of the following best describes the method used by the principal?

It's an unfair method because each student will not post the same outcomes.
It's a fair method because each result is an equally likely possible outcome.
It's a fair method because it's a limited number of students.
It's an unfair method because two or more students could get the same results.

Step-by-step explanation:

The reasonable range of the given function is given by {130, 260, 390, 520, .......}.

A range can be defined as the set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range simply refers to the set of all possible output numerical values, which are shown on the y-axis of a graph.

In order to determine the reasonable range of the given function, we would create an input and output table to model the relationship between the range and domain as follows:

x         130x         y___

1          130(1)       130

2         130(2)      260

3         130(3)      390

4         130(4)      520

Therefore, the reasonable range of the given function is given by {130, 260, 390, 520, .......}.

39 is a composite numbers out of 7 13 39 97.

A composite number is one that can be generated by multiplying two smaller positive numbers. It is a positive integer with at least one divisor other than 1 and itself. Every positive integer is either composite, prime, or the unit 1, hence composite numbers are those that are neither prime nor a unit.

The integer 14 is a composite number, for example, since it is the product of the two smaller integers 2 7 Similarly, the numerals 2 and 3 are not composite numbers because they can only be divided by one and themselves.

Step-by-step explanation:

Given

We know that Area of the rectangle

A=wl

  = (3x³+8x²+x) × (6x³)

  [tex]=\left(6x^3\right)\times \:3x^3+\left(6x^3\right)\times \:8x^2+\left(6x^3\right)x[/tex]

  [tex]=3x^3\left(6x^3\right)+8x^2\left(6x^3\right)+x\left(6x^3\right)[/tex]

Thus, the area of the rectangle will be:

Answer:

(2, -6, 1)

Step-by-step explanation:

Multiplying the first equation by 2 yields 4x+2y-2z = -6.

Adding this to the second equation, we get 9x=18, and thus x=2.

From the third equation, we know z=1.

From the first equation, it follows that y = -6.

Answer:

Step-by-step explanation:

Sides of the triangle are

a = 330 ft

b = 180 ft

c = 420 ft

From cosine rule we have

[tex]\angle A=\cos^{-1}(\dfrac{b^2+c^2-a^2}{2bc})\\ =\cos^{-1}(\dfrac{180^2+420^2-330^2}{2\times180\times 420})\\ =48.65^{\circ}[/tex]

[tex]\angle B=\cos^{-1}(\dfrac{a^2+c^2-b^2}{2ac})\\ =\cos^{-1}(\dfrac{330^2+420^2-180^2}{2\times 330\times 420})\\ =24.17^{\circ}[/tex]

[tex]\angle C=\cos^{-1}(\dfrac{a^2+b^2-c^2}{2ab})\\ =\cos^{-1}(\dfrac{330^2+180^2-420^2}{2\times 330\times 180})\\ =107.19^{\circ}[/tex]

The coordinates of Z will be  Z(8,6) and Z(4,2)

The formula for the area of triangle is given as :

               A = 1/2 * b * h

where , b = base

            h = height

We have been a ΔXYZ with coordinates of

    X(-2,2) and Y(8,2)

Also the given area is 20 sq. units

We need to find the coordinates of Z from the given question.

First we will find the length of XY which is

XY = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2}- y_{1}) ^{2} } \\[/tex]

     = √(8+2)² + (2-2)²

     = √100

     = 10 units

Let z= (0,6)

distance of YZ = √(0-8)² + (6-2)²

                        = √64+ 16

                        = √80

Area = 1/2 * 10* 4√5 = 20√5 ≠ 20

Let Z = (8,6)

distance of YZ = √(8-8)² + (6-2)²

                        = √16

                        = 4

Area = 1/2 * 10* 4 = 20

let Z = (4,2)

distance of YZ = √(4-8)² + (2-2)²

                        = √16

                        = 4

Area = 1/2 * 10* 4= 20

Let Z = (7,-2)

distance of YZ = √(7-8)² + (-2-2)²

                        = √1 + 16

                        = √17

Area = 1/2 * 10* √17 = 5√17 ≠ 20

Hence the coordinates of Z will be Z(8,6) and Z(4,2) as putting these value we get area equal to 20 square units.
