Using the concepts of probability, we got that  0.063 is the probability of picking a blue marble randomly out of a bag of 6 blue marbles, 3 black marbles, and 8 orange marbles while rolling a 3 on a 6-sided dice at the same time

We know very well that probability is defined as the fraction of number of favorable outcomes to the total number of outcomes.

Here, we are rolling a 6-faced dice.

Getting 3 on the top face of dice is same as the any number getting from 1 to 6 on the top face of the dice.

So, every number has equal probability to come on the top face,  therefore the probability of getting 3 on the top face of dice is (1/6)

Now, similarly total number of marbles in the bag=6 blue +3 black+8 orange marble=17 marbles.

Now, picking one marble from 17 marble is can be done in \(^1^7C_1\)  ways, similarly  choosing 1 blue marble from 6 marble can be done in \(^6C_1\) ways.

So, probability of picking 1 blue marble randomly=6/17

Now, the probability of picking 1 blue marble from 17 marbles along with rolling dice probability is given by =(6/17)×(1/6)=(1/17)=0.063

Hence, the probability of picking a blue marble randomly out of a bag of 6 blue marbles, 3 black marbles, and 8 orange marbles while rolling a 3 on a 6-sided dice at the same time is 0.063

Answer:

  shifted down 4 units

Step-by-step explanation:

You want to know the effect on the graph of changing y=2x+2 to y=2x-2.

The constant in the equation y=2x+2 is the y-intercept. The line described by this equation crosses the y-axis at y=2.

When the equation is changed to y=2x-2, the y-intercept changes from +2 to -2, a shift down of 4 units. The shifted line has the same slope as the original, so is parallel to it.

The effect on the graph is to move it down 4 units.

Explanation:

Given problem;

 To solve for the slope of the line;

The slope of a line is the vertical distance to the horizontal displacement on a line.

  Slope  = \(\frac{Vertical distance}{horizontal displacement}\)

For lines such as this, we use the formula below;

                        Slope  = \(\frac{y_{2} - y_{1} }{x_{2} - x_{1} }\)

To find the slope reference the image attached;

     point 1 (0,4)      x₁  = 0   y₁  = 4

     point 2 (2,-2)    x₂  = 2   y₂  = -2

Now input the parameters and solve;

          Slope  = \(\frac{-2 - 4}{2 - (0)}\)   =    \(\frac{-6}{2}\)  

          Slope  = -3

The slope of the line is -3

If A and B are ANY two sets with ACB,

a. The statement is false.

b. The statement is false.

This statement is true. If the set difference (B\A) is empty, it means that every element in B is also in A. In other words, A is a subset of B (A ⊆ B).

Counter-example:

Let A = {1, 2} and B = {1, 2, 3}. In this case, (B\A) = {3}, which is not empty. Therefore, the statement is false.

b. If Aᶜ ⊆ B, then (B\A) = Ø.

This statement is false. If the complement of A, Aᶜ, is a subset of B, it does not necessarily imply that (B\A) is empty.

Counter-example:

Let A = {1, 2} and B = {1, 2, 3}. In this case, Aᶜ = {3}, which is a subset of B. However, (B\A) = {3}, which is not empty. Therefore, the statement is false.

The probabilities for exact 8 and less than 8 calls can be obtained as  0.1009 and 0.1785 respectively.

Poisson distribution is applied for the case where the events occur in a specific period of time with constant rate.

The given case belongs to Poisson distribution,

It can be solved as follows,

(a) The probability of exactly 8 calls can be obtained as,

P(Exact 8 calls) =  \(e^{-\lambda} \lambda^{x}/x!\)

Where x = 8 and λ = 2.1 × 5 = 10.5.

Then, the probability is  obtained as,

⇒ e⁻⁸ × 10.5⁸/8!

⇒ 0.1009

It implies that if 100 calls are selected randomly for the interval of 5 minute, 10 calls can be expected.

(b)  The probability of less than 8 calls can be obtained as

P(Less than 8) = \(\sum_{x =1}^{7}e^{-\lambda}\lambda^{x}/ x!\)

⇒ P(Less than 8) = 0.1785

It implies that out of 100 randomly selected 5 minute calls, around 18 have less than 8 calls.

Hence, the required probabilities for the given case are 0.1009 and 0.1785 respectively.

Answer:

x = -2y+77

y =  -x/2+77/2

Step-by-step explanation:

The equation for x variable is x = 77 - 2y and for y variable it is; y =  77- x/2

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

WE have been given linear equation in two variables: 2x + 4y - 31 = 123.

Solve for x and for y

2x + 4y - 31 = 123.

Add 31 to both sides

2x + 4y - 31 + 31 = 123 + 31

2x + 4y = 154

Solving for x then Subtract 4y from both sides

2x + 4y -4y = 154 - 4y

2x = 154 - 4y

Divide by 2

x = 77 - 2y

y =  77- x/2

The slope of the line represents the rate of change between the independent variable (number of available staff) and the dependent variable (number of available staff) (wait time).

The slope of the line in this case is -1.62, which means that for every one unit increase in the number of staff available, the wait time decreases by 1.62 units.

In this case, a negative slope indicates that as the number of staff available increases, so does the wait time, indicating a positive relationship between the two variables. In other words, as the number of employees available increases, the wait time decreases.

It is important to remember that the equation models this relationship, and that actual wait times in the real world may not always follow this exact relationship due to other factors that influence wait times.

Answer:

\(135^\circ\)

Step-by-step explanation:

To convert radians to degrees, use the formula \(x^\circ=r\frac{180}{\pi}\) where \(r\) is the number of radians:

\(x^\circ=r\frac{180}{\pi}\)

\(x^\circ=(\frac{3\pi}{4})(\frac{180}{\pi})\)

\(x^\circ=\frac{540}{4}\)

\(x^\circ=135\)

Therefore, \(\frac{3\pi}{4}\) radians is \(135^\circ\)

The figures that have rotational symmetry are:

Option D: Hexagon

Option E: Cross

Rotational symmetry, is also known as radial symmetry is defined as the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct orientations in which it looks exactly the same for each rotation.

Hexagon: The six sides of the hexagon are congruent, as they are all equal and this tells us that no mater the rotation it will always be the same.

The Cross: The four corners of the cross are equal and this tells us that no matter the rotation it will always be the same.

All the other figures have sides that are NOT congruent as they have different side lengths

Answer:

\(A = 66\ yd^2\)

Step-by-step explanation:

You can either add up all the areas of the faces of the rectangular prism, or you can use the following formula:

\(A = 2(wl+hl+hw)\\A = 2(3 \times 3 + 4 \times 3 + 4 \times 3)\\A = 2(9+12+12)\\A = 2(33)\\A = 66\)

Answer:

The surface area of the rectangular prism is \(66\ yd^2\)

Step-by-step explanation:

Step 1:  Find the area of the front and back

\(A = l * w\)

\(A = 3\ yd * 4\ yd\)

\(A = 12\ yd^2 * 2\)

\(A = 24\ yd^2\)

Step 2:  Find the area of the top and bottom

\(A = l * w\)

\(A = 3\ yd * 3\ yd\)

\(A = 9\ yd^2 * 2\)

\(A = 18\ yd^2\)

Step 3:  Find the area of the left and right sides

\(A = l * w\)

\(A = 3\ yd * 4\ yd\)

\(A = 12\ yd^2 * 2\)

\(A = 24\ yd^2\)

Answer:

The probability of a student to hit any small circle is 4.66 %.

Step-by-step explanation:

In order to determine the probability of the students to hit the small circles, we need to calculate the are of the rectangle and the area of each circle. These are shown below:

area circle = pi*r² = pi*(3)² = 28.26 in²

area rectangle = 35*52 = 1820 in²

Since there are three circles and the students can hit any of those the probablity of hitting them is given by the area of one circle multiplied by 3 and divided by the area of the rectangle.

p = [(3*area circle)/(area rectangle)]*100%

p = [(3*28.26)/1820]*100 = 4.66 %

Since L/K is not separable, it is a non-separable extension of K. Therefore, for every prime number p, the extension L/K where L is the splitting field of x^p - a for some a in K is an example of a non-separable extension of a suitable field of characteristic p.

To give an example of a non-separable extension of a suitable field of characteristic p for every prime number p, we need to first understand what a separable extension is. A separable extension of a field K is an extension L/K such that every element of L is a root of a separable polynomial over K. In other words, if an irreducible polynomial over K has multiple roots in L, then the extension L/K is not separable.

Now, let's consider the case of a field of characteristic p. If K is a field of characteristic p, then every element of K satisfies the equation x^p = x. This is known as the Frobenius map, and it has the property that it is an automorphism of K.

So, if we consider the extension L/K where L is the splitting field of the polynomial x^p - a for some a in K, then L/K is not separable. This is because the polynomial x^p - a has p roots in L, namely {a^(1/p), a^(1/p) * ζ, a^(1/p) * ζ^2, ..., a^(1/p) * ζ^(p-1)}, where ζ is a primitive p-th root of unity.

Length (l) = 25cm

width (b) = 5cm

height (h) = (x-2)cm.

a).

Volume= l*b*h

V = 25*5*(x-2)

V = 125(x-2)

V = 125x - 250 → Answer

b).

V = 750cm³

V = 125x - 250

750 = 125x - 250..........(i)

(ii)

The equation (i) is: 750 = 125x - 250

or, 125x = 750+250

or, 125x = 1000

or, X = 1000/125

Therefore, X= 8cm.
