To calculate the product of two random variables that follows the normal distribution with mean 0 and variance 1 by using the covariance formula

Cov(X, Y) = E[XY] - E[X]E[Y] = E[XY] - 0 = E[XY]

Given that two random variables follow a normal distribution with mean 0 and variance 1.

Let X and Y be two independent normal random variables such that X ~ N(0,1) and Y ~ N(0,1)

Now, The expected value of the product of two random variables is given by;

E[XY] = E[X]E[Y] + Cov(X,Y)

Where E[X] and E[Y] are the means of the two random variables X and Y respectively.

Cov(X, Y) is the covariance between the two random variables, which can be calculated using the formula;

Cov(X,Y) = E[XY] - E[X]E[Y]

Now, E[X] = E[Y] = 0 as both have a mean of 0.

Cov(X, Y) = E[XY] - E[X]E[Y]

⇒ E[XY] = the expected value of the product of X and Y.

As X and Y are independent, their covariance will be zero, which implies;

Cov(X, Y) = E[XY] - E[X]E[Y] = E[XY] - 0 = E[XY]

Thus, we can calculate the product of two random variables that follow a normal distribution with mean 0 and variance 1 using the above formula for covariance.

The given augmented matrix is equivalent to a system of linear equations with 1 equation and 3 variables. The system is underdetermined and the solution to the system is [tex](x, y, z)[/tex]= (0, 0, 0).

The given augmented matrix is in row-reduced form and is equivalent to a system of linear equations. The matrix has 3 columns and 1 row, so there is 1 equation and 3 variables in the corresponding system of linear equations. Since there is only one equation, the system is underdetermined and has infinitely many solutions.

The solution to the system can be stated as: (x, y, z) = (0, 0, 0). The solution is a point where all the variables are equal to zero. Since the matrix is in row-reduced form, this is the only solution to the system. If the augmented matrix was not in row-reduced form, then the solution would be stated as a parameter, such as (x, y, z) = (0, 0, t), where t is a parameter.

Answer:

Step-by-step explanation:

For the given augmented matrix, you want to know the number of equations and variables it represents, whether the system is under- or over-determined, and the solution, using parameters as required.

  [tex]\left[\begin{array}{ccc|c}1&\dfrac{1}{4}&-\dfrac{1}{4}&1\\\vphantom{\dfrac{T}{q}}0&0&0&0\end{array}\right][/tex]

Each column of the augmented matrix is the coefficient of the variable in a linear equation represented by the row. The first row of the matrix represents the equation ...

  [tex]1x +\dfrac{1}{4}y-\dfrac{1}{4}z=1[/tex]

The second row of the matrix represents the tautology ...

  0x +0y +0z = 0

It contributes no information about the relationships between the variables.

The matrix represents 1 equation in 3 variables.

For there to be a unique solution to a linear system, there must be as many consistent and independent equations as there are variables. Here, there are fewer equations than variables. This system is underdetermined.

The solution to an underdetermined system can be written in terms of parameters of free choice. We will need as many parameters as there are missing equations: 2.

Here, the coefficients of y and z suggest we choose parameters that let us represent those values as multiples of 4.

Parameters: s, t

Let y = 4s, z = 4t. Then the equation becomes ...

  x +1/4(4s) -1/4(4t) = 1

  x +s -t = 1

  x = 1 +t -s

Now, the solution can be written as ...

  (x, y, z) = (1 +t -s, 4s, 4t)

The width of the rectangular field is 51 meters

To find the width of the rectangular field, we need to use the formula for the perimeter of a rectangle, which is:

Perimeter = 2 × (length + width)

We are given that the perimeter of the rectangular field is 292 m and the length is 95 m. So, we can plug in these values into the formula and solve for the width:

292 = 2 × (95 + width)

First, we can simplify the right side of the equation:

292 = 190 + 2 × width

Next, we can isolate the variable (width) on one side of the equation by subtracting 190 from both sides:

292 - 190 = 2 × width

102 = 2 × width

Finally, we can solve for the width by dividing both sides by 2:

The explicit formula for the given sequence 8, 20, 50, 125, 312.5, ... is a_n = 8 × 2.5^(n-1)

To find an explicit formula for the given sequence, we first need to identify the pattern or rule that generates the terms.

Looking at the sequence, we can see that each term is obtained by multiplying the previous term by a fixed factor and then adding a constant.

To find this factor and constant, we can use the general form of a geometric sequence:

a_n = a_1 × r^(n-1)

where a_n is the nth term, a_1 is the first term, r is the common ratio, and n is the index of the term.

Using the first two terms of the sequence, we can find the common ratio:

r = a_2 / a_1 = 20 / 8 = 2.5

Now we can use the first term and the common ratio to find the constant term

a_1 = 8 = a_1 × 2.5^(1-1) + c

c = 8 - a_1 = 0

Therefore, the explicit formula for the given sequence is:

a_n = 8 × 2.5^(n-1)

The calculation shows that 9,000 scientists have seen the deep ocean through Alvin's windows; and

a total of 13,500 people have traveled in Alvin over the course of its 4,500 dives.

1) If on each of the 4,500 dives Alvin carried a new pilot and two new scientists, then the total number of scientists who have seen the deep ocean through Alvin's windows is:

4,500 dives x 2 scientists per dive = 9,000 scientists

Therefore, 9,000 scientists have seen the deep ocean through Alvin's windows.

2) To calculate the total number of people who traveled in Alvin, we can add the number of pilots and scientists on each dive and multiply by the number of dives:

4,500 dives x (1 pilot + 2 scientists)

= 4,500 x 3

= 13,500 people

The total advertising cost for the campaign is $59,200,000.

To calculate the total cost for each advertising medium, we need to multiply the number of impressions by the cost per thousand impressions (CPM) and divide by 1000 to get the total cost in dollars.

Adding up all of the costs, we get $12,750,000 + $87,500 + $15,000 + $62,500 = $12,915,000.

However, we need to remember that the digital advertising has a CPM of $4.69 instead of the listed cost, so we need to recalculate its cost to be $32000000 x $4.69 CPM / 1000 = $150,080. Adding this to the total cost gives $12,915,000 + $150,080 = $13,065,080. This is the cost before the GRPS and CPP discounts are applied.

To apply these discounts, we need to multiply the total cost by (1 - GRPS) and then divide by CPP. Plugging in the values given, we get ($13,065,080 x (1 - 0.25)) / 1500 = $48,928.50. Finally, we need to multiply this by the total number of impressions to get the overall cost of the campaign, which is $48,928.50 x 1,200,000,000 / 1000 = $59,200,200, or approximately $59,200,000.

Answer: This statement is known as the Law of Sines and can be proven using trigonometry and the properties of similar triangles.

Consider a triangle ABC with sides of lengths a, b, and c opposite to the angles A, B, and C respectively. Let's draw an altitude from vertex A to side BC, splitting side BC into two segments: BD of length x and CD of length c-x.

Using the Pythagorean theorem, we can write:

a^2 = x^2 + h^2 (1)

b^2 = (c-x)^2 + h^2 (2)

where h is the length of the altitude from A to BC.

Dividing equation (1) by sin^2(A) and equation (2) by sin^2(B), we get:

a^2 / sin^2(A) = x^2 / sin^2(A) + h^2 / sin^2(A)

b^2 / sin^2(B) = (c-x)^2 / sin^2(B) + h^2 / sin^2(B)

Since angles A and B are complementary (i.e. A + B = 90 degrees), we have sin(A) = cos(B) and sin(B) = cos(A). Substituting these identities and rearranging the equations, we get:

a^2 / sin(A) = x / cos(B) + h / sin(B)

b^2 / sin(B) = (c-x) / cos(A) + h / sin(A)

Multiplying both equations by sin(A)sin(B), we obtain:

a^2 sin(B) = x sin(A) cos(B) + h sin(A)

b^2 sin(A) = (c-x) sin(B) cos(A) + h sin(B)

Now, we use the fact that h = a sin(B) = b sin(A), which follows from the definition of sine as opposite/hypotenuse. Substituting this into the above equations and simplifying, we get:

a / sin(A) = 2R

b / sin(B) = 2R

c / sin(C) = 2R

where R = a/(2sin(A)) = b/(2sin(B)) = c/(2sin(C)) is the radius of the circumcircle of triangle ABC. This is the Law of Sines in its usual form.

From this, we can see that the ratio of the sines of any two angles in a triangle equals the ratio of the lengths of their opposite sides, as required.

Answer:

So 3 blue buckets and 4 white buckets were purchased

Step-by-step explanation:

We can solve this by algebra

Let B = number of blue buckets bought

Let W = number of white buckets bought

Total buckets bought:
B + W = 7    (1)

Each blue bucket can hold 2 gallons of water
So B blue buckets can hold 2B gallons of water

Each white bucket can hold 5 gallons of water
So W white buckets can hold 5W gallons of water

Totally they can hold
2B + 5W gallons

We are given that they both can hold  26 gallons of water

So our second equation is
2B + 5W = 26   (2)

By eliminating one of the variable terms we can solve for the other variable term

Let's eliminate the term for variable B

Multiply equation (1) by 2

(1) x 2 ==> 2(B + W) = 2(7)

2B + 2W = 14    (3)

Subtract (3) from (2); B terms are same so they cancel out

(2) - (3):
2B + 5W = 26    [tex]\bold{-}[/tex]
2B + 2W = 14
---------------------
0    +  3W = 12
------------------------

3W = 12
W = 12/3

W = 4

Substitute W= 4 in equation 1
B + W = 7
=> B + 4 = 7

B = 3

So 3 blue buckets and 4 white buckets were purchased

The total number of students which attend the art class is 52 which is 89.75 of the total enrolled students that is 58.

A Latin word with the meaning "out of one hundred" is percentage.

Working with parts of 100 is much easier than working with thirds, twelfths, and other fractions, especially since many fractions lack a consistent (non-recurring) decimal equivalent.

Significantly, this also makes comparing percentages more simpler than comparing fractions with various denominators. This contributes to the widespread usage of the metric measuring system and decimal currencies.

Total students enrolled for art class = 58

Percentage of cancelled students = 10.3%

Then, Percentage of non-cancelled students = 100 - 10.3 = 89.7%

So,

Attended students = 89.7% of 58.

= 89.7*58 / 100

= 52.06

The answer that is NOT true when two relations Rand S are union-compatible is: Rand S must have the same number of tuples.

A relation is a set of attributes that describe a set of entities (or elements). The union-compatible operation allows you to combine two relations into one with the same attribute set.

The union-compatible operation is performed on two relations that have the same number of attributes and the same domain in each attribute. The union-compatible operation is sometimes known as the union operation.

Assume that two relations Rand S are union-compatible. Then it implies that both relations have the same number of attributes and the domain of the i-th attribute of R must be the same as the domain of the i-th attribute of S.

Thus, the correct option is D and A i.e.

"The domain of the i-th attribute of R must be the same as the domain of the i-th attribute of S".

In relational algebra, the difference operation (-) is used to find the differences between two relations. When two relations R and S are union-compatible, then we can perform the difference operation. Hence, option (b) is true. But option (c) is false as there is no compulsion that two relations Rand S must have the same number of tuples.
