The expectation values are <x> = 1.25 x 10⁻¹⁰ ,  <x²>  =  2.07 x 10⁻²⁰

What is average?

The middle number, which is determined by dividing the sum of all the numbers by the total number of numbers, is the average value in mathematics. When determining the average for a set of data, we add up all the values and divide this sum by the total number of values.

We need to find expectation value of <x> and < x²>

average value for <x>   is given by a/2   where a = length of box

hence <x> = ( (2.5 x 10⁻¹⁰) /2) = 1.25 x 10⁻¹⁰

hence <x²> = (1.25 x 10⁻¹⁰)²  = 1.56 x 10⁻²⁰

<x²> = ( a/2 x 3.14 x n)²   x ( 4 x 3.14² x n² /3  -2)

hence <x²>  = ( 2.5 x 10⁻¹⁰ / 2 x 3.14 x 5)²   x ( 4 x 3.14² x 5² /3  -2)

  <x²>  =  2.07 x 10⁻²⁰

<x²>  is not equal to <x>²

The expectation values are <x> = 1.25 x 10⁻¹⁰,  <x²>  =  2.07 x 10⁻²⁰

The probability of having a 4 in a 30 roll is 5 times

The expected value, μ, of rolling a 4 on a fair number cube (with faces numbered 1 to 6) can be found by using the formula μ = np, where n is the number of trials (30 in this case) and p is the probability of success for an individual trial (rolling a 4).

The probability of rolling a 4 on a fair number cube is 1/6. Therefore, the expected value of rolling a 4 30 times can be calculated as follows:

μ = 30 * (1/6) = 5

So, Mr. Jackson can expect to roll a 4 approximately 5 times in 30 rolls of his number cube.

17 students played cricket more than basketball.

A pie chart is a type of graph where a circle is divided into certain sectors where each sector shows a proportion of the whole.

Pie chart showing the preference of the students is given below.

Total number of students = 300

We know that total degree of the circle = 360°

Students who played cricket = 90°

Number of students who played cricket will be (90° / 360°)th of 300.

Number of students who played cricket = (90° / 360°) × 300

                                                                   = 75

Students who played basketball = 70°

Number of students who played basketball = (70° / 360°) × 300

                                                                         = 58.33 ≈ 58

Students played cricket - Students played basketball = 75 - 58 = 17

Hence there are 17 students more in cricket than that in basketball.

The equations Ax = b are not compatible.

It is represented by an equal sign (=) and is used to solve for unknown values or to describe relationships between variables. Equations can be simple or complex, involving basic arithmetic operations or advanced mathematical concepts like trigonometry and calculus.

An equation can be used to solve for a single unknown value, for example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving us 2x = 4 and then dividing both sides by 2, giving us x = 2. In this example, x = 2 is the solution to the equation.

To determine whether the equations Ax = b are compatible and to compute a solution x, you would first form the augmented matrix [A|b]. Then, you would perform row operations on [A|b] to reduce it to an upper triangular matrix [C|d]. Finally, you would use the software package to solve the square system of equations Cx = d.

If the software terminates with an error message, it means that C is singular, and the equations Ax = b are not compatible. If the software finds the unique solution of Cx = d, it means that the equations Ax = b are compatible and that the solution x is unique. However, it is important to note that the uniqueness of the solution depends on the rank of A being equal to n. If the rank of A is less than n, the equations are not compatible, and if the rank of A is greater than n, the equations have infinitely many solutions.

Step-by-step explanation:

x = (300 - p) / 20

According to the equation, the quantity of kilos (x) of snig that will be sold is equal to the difference between 300 and p, divided by 20.

The price-demand connection for roast snig at the harvest festival on the planet Bozone can be represented by the equation p=300 - 20x. The formula specifies that 300 minus 20 times the number of kilogrammes (x) of snig sold is the price per kilogramme of snig (p) in the local currency (Bozats).

Using this equation, one can determine how much of the price must be reduced in order to sell 1 extra kilogramme of snig. The equation can be rewritten to solve for x in terms of p in order to accomplish this. This can be done by taking 300 off of both sides of the equation, multiplying both sides by 20, and then solving for x = (300 - p) / 20. This rearrangement has the effect of dividing the number of kilogrammes of snig that will be sold in terms of price per kilogramme by the difference between 300 and p. This equation can be used to calculate the price reduction required to sell an extra kilogramme of snig.

The probability that daily production is between 28 and 45.9 liters is 0.024.

Standard deviation is the positive square root of the variance. Standard deviation is one of the basic methods of statistical analysis. Standard deviation is commonly abbreviated as SD and denoted by 'σ’ and it tells about the value that how much it has deviated from the mean value.

Given that, x₁=28, x₂=45.9, μ=38 and σ =4.3

We know that, Z=(x-μ)/σ

Z=standard score, x=observed value, μ=mean of the sample and σ=standard deviation of the sample

z =(38-28)/4.3= 2.32 and probability on the z-table is 0.9896

z = (38-45.9)/4.3 = -1.83 and probability on the z-table is 0.9656,  

Now, P(2.32<z<-1.83) = 0.9896-0.9656

The total production of both countries when they did not specialize was 91 million / day.

Given the information that when the two countries did not specialize, the total production of chinos was 23 million pairs per day, and the total production of pistachios was 68, we can calculate the total production of both countries with the following equation:

Total Production = Chinos (23 million pairs / day) + Pistachios (68 million / day)

Therefore, the total production of both countries when they did not specialize was 91 million / day. This can be calculated as:

Total Production = 23 million pairs + 68 million = 91 million / day

Hence, the total production of both countries when they did not specialize was 91 million / day. This calculation can be represented by the following formula:

Total Production = Chinos (x) + Pistachios (y)

Given that,

Let the amount of time it takes for E to increase by 10% be x.

Thus, after (t + x) seconds, E is increased by 10%.

E(t + x) = E(t) + 10% of E(t)

= E(t) + 10/100 E(t)

= E(t) + 0.1 E(t)

E(t + x) / E(t) = 1.1

As,

[tex]E(t) = 6(1.02)^t\\\\E(t + x) = 6(1.02)^{t + x}\\\\\frac{E(t + x)}{E(t)} = \frac{6(1.02)^{t + x}}{6(1.02)^{t}}\\\\\frac{E(t + x)}{E(t)} = (1.02)^{t + x - t}\\\\(1.02)^x = 1.1[/tex]

(200 - 100√2) / 16 is the rectangular form of the product c1*c2 for an equilateral triangle's vertices.

A triangle is a three-sided polygon that is sometimes (but not always) referred to as the trigon. Every triangle has three sides and three angles, which may or may not be the same.

Here,

An equilateral triangle is a triangle with three equal sides. If 3-2i, 6-i, and c form the vertices of an equilateral triangle, then the distance between 3-2i and 6-i is equal to the distance between 3-2i and c.

The distance between two complex numbers a + bi and c + di can be found using the formula:

√((c - a)² + (d - b)²)

So, the distance between 3-2i and 6-i is:

√((6 - 3)² + (-1 - (-2))²) = √((3)² + (1)²) = √(9 + 1) = √10

And the distance between 3-2i and c is:

√((c - 3)² + (c - (-2))²) = √((c - 3)² + (c + 2)²)

Since these distances must be equal, we have:

√((c - 3)² + (c + 2)²) = √10

Squaring both sides:

(c - 3)² + (c + 2)² = 10

Expanding both sides:

c² - 6c + 9 + c² + 4c + 4 = 10

Combining like terms:

2c² + 10c + 5 = 10

Subtracting 10 from both sides:

2c² + 10c - 5 = 0

This is a quadratic equation, which can be solved using the quadratic formula:

c = (-b ± √(b² - 4ac)) / 2a

Where a = 2, b = 10, and c = -5. Plugging these values into the formula:

c = (-10 ± √(10² - 4 * 2 * -5)) / 2 * 2

c = (-10 ± √(100 + 40)) / 4

c = (-10 ± √(140)) / 4

c = (-10 ± 10√2) / 4

So there are two complex solutions, c1 = (-10 + 10√2) / 4 and c2 = (-10 - 10√2) / 4.

The product of these two solutions is:

c1 * c2 = ((-10 + 10√2) / 4) * ((-10 - 10√2) / 4)

= (100 - 100√2 + 100) / 16

= (200 - 100√2) / 16

(200 - 100√2) / 16 is the answer in rectangular form for the product c1*c2 for the vertices of an equilateral triangle.

One possible choice for p(x) is x² - 1, and one possible choice for q(x) is x² + x - 2. These polynomials satisfy the required property (i.e., their derivatives at x=1 are equal to the polynomials themselves evaluated at x=1), and they are linearly independent because their leading terms (x² in both cases) are distinct.
