The expected number of visits to the course website is option (c) 0.80

In this case, the possible outcomes are the number of visits to the course website, which are 0, 1, 2, and 3, with respective probabilities of 0.45, 0.35, 0.15, and 0.05.

To find the expected number of visits to the course website, we use the following formula:

Expected value = Σ(xi * P(xi)), for i = 1 to n

where xi is the value of the i-th outcome, P(xi) is the probability of the i-th outcome, and n is the total number of possible outcomes.

Using this formula, we get:

Expected value = (0 x 0.45) + (1 x 0.35) + (2 x 0.15) + (3 x 0.05)

= 0 + 0.35 + 0.3 + 0.15

= 0.80

In conclusion, the correct answer to the question is (c) 0.80, and it was obtained by using the formula for the expected value of a probability distribution.

An elliptic curve is a graphical representation of a polynomial equation of degree 3. The given equation is y2 = x3 + x + 28. The elliptic curve E can be determined by plotting the points of solutions of the equation y2 = x3 + x + 28.

In this case, the elliptic curve E is defined over Z71, which is the set of integers modulo 71. The points on the elliptic curve E can be found by substituting values of x into the equation y2 = x3 + x + 28 and solving for y. This can be done for all values of x in Z71. However, since the set of integers, modulo 71 is finite, it is possible that some values of x may not have a corresponding value of y. Therefore, some points on E may not exist in Z71.To find all the points that lie on E, we need to first find the points that lie on the curve in the affine plane, and then add the point at infinity if it exists. To find the points on the curve in the affine plane, we substitute all values of x in Z71 into the equation y2 = x3 + x + 28 and solve for y. If a value of y exists, then the point (x,y) lies on E. To find all the points on E, we substitute all values of x in Z71 into the equation y2 = x3 + x + 28 and solve for y. Since Z71 is a finite set, we can use a computer program to generate all values of x in Z71, and then find the corresponding values of y. We can then plot the points (x,y) on a graph to get the elliptic curve E. Alternatively, we can use the group law to generate all points on E. To do this, we choose a base point P on E and then apply the group law to generate all points on E. The group law states that for any two points P and Q on E, there exists a third point R on E such that P + Q + R = 0, where 0 is the point at infinity. Using this property, we can generate all points on E by repeatedly adding the base point P to itself. The set of all points generated in this way forms a group, which is denoted by E(Z71).

In summary, the elliptic curve E defined by y2 = x3 + x + 28 over Z71 can be determined by finding all the points that lie on the curve in the affine plane and then adding the point at infinity if it exists. This can be done by substituting all values of x in Z71 into the equation y2 = x3 + x + 28 and solving for y. Alternatively, we can use the group law to generate all points on E. The set of all points generated in this way forms a group, which is denoted by E(Z71).

Answer:

x = 105

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 7, thus

sum = 180° × 5 = 900°

Sum the interior angles and equate to 900

x + 102 + 165 + 123 + x + 11 + 128 + 161 = 900, that is

2x + 690 = 900  ( subtract 690 from both sides )

2x = 210 ( divide both sides by 2 )

x = 105

If we were to measure a dependent variable's frequency, the appropriate method would be to count the number of times it occurred.

Frequency refers to the rate at which a behavior or event happens within a given timeframe. By counting the occurrences of the dependent variable, we can determine how often it happens or the number of times it is observed. The other options mentioned—timing the interval between responses, measuring the shape of the behavior, and timing how long it took to achieve—are not directly related to measuring frequency.

Timing the interval between responses would be more relevant for measuring the interresponse time or the duration between two consecutive instances of the behavior. Measuring the shape of the behavior would involve analyzing the pattern or characteristics of the behavior, such as its intensity or duration. Timing how long it took to achieve something would focus on the duration or latency of the behavior rather than its frequency.

Therefore, the correct approach for measuring frequency would be to count the number of occurrences of the dependent variable, providing an objective and quantitative assessment of how frequently the behavior or event takes place.

For any price of h and k = -12, the system x + 3y = h and -4x + ky = -9 will haven't any answer.

To determine the values of h and okay for which the device of equations has no answer, we want to locate the situations underneath which the equations are inconsistent or parallel.

The given system of equations is:

Equation 1: x + 3y = h

Equation 2: -4x + ky = -9

For the gadget to haven't any answer, the lines represented with the aid of these equations should be parallel and in no way intersect. In different phrases, the slopes of the traces need to be equal, but the y-intercepts should be specific.

Let's first discover the slopes of the traces. The slope-intercept form of Equation 1 is y = (-1/3)x + (h/3), wherein the slope is -1/3. The slope-intercept shape of Equation 2 is y = (4/k)x - (9/k), wherein the slope is 4/k.

For the strains to be parallel, the slopes should be equal. Therefore, we have the condition: -1/3 = 4/k.

To locate the values of h and okay for which the gadget has no answer, we need to locate the values of h that satisfy the situation -1/3 = 4/k.

Solving this equation for ok, we've got:

-1/3 = 4/k

-1 = 12/k

k = -12

Substituting k = -12 returned into the equation -1/3 = 4/k, we've:

-1/3 = 4/(-12)

-1/3 = -1/3

Since the equation holds real for any value of h, there aren't any restrictions at the price of h.

Therefore, for any price of h and k = -12, the system x + 3y = h and -4x + ky = -9 will haven't any answer.

The system of equations has no solution when k is equal to 12. The value of h can be any real number.

To determine the values of h and f for which the system has no solution, we need to analyze the coefficients of the variables and the constants in the equations.

The given system of equations is:

x + 3y = h

-4x + ky = -9

We can rewrite the second equation as:

-4x + ky = -9

Dividing both sides of the equation by -4, we get:

x - (k/4)y = 9/4

Comparing the coefficients of x and y in the two equations, we can see that the slopes of the lines represented by the equations are different when k is not equal to 12.

Therefore, for the system to have no solution, k must be equal to 12.

As for the value of h, it can be any real number since it does not affect the slopes of the lines.

We need 588.75 square inches of leather to create the travel case which is cylindrical.

The surface area of a cylinder is given by the formula:

A = 2πr² + 2πrh

where r is the radius of the circular base, h is the height of the cylinder, and π is the mathematical constant pi, which is approximately equal to 3.14.

In this case, we are given that the cylinder has a diameter of 15 inches, so the radius is 7.5 inches (half of the diameter).

We are also given that the height of the cylinder is 5 inches.

Using these values in the formula, we can calculate the surface area of the cylinder as:

A = 2π(7.5)² + 2π(7.5)(5)

= 2π(56.25) + 2π(37.5)

= 2(π)(93.75)

= 187.5π

The best estimate of the number of ants in Mrs. Brown's yard is 15,116,596.

What is arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a fixed constant number, called the common difference, to the preceding term.

Mrs. Brown's yard has three ant hills, each with a different number of ants. To estimate the total number of ants in the yard, we simply add up the number of ants in each hill.

The first hill has 4,867,190 ants, the second has 6,256,304, and the third has 3,993,102. When we add these numbers together, we get a total of 15,116,596 ants in Mrs. Brown's yard. Of course, this is just an estimate, as there may be other ant hills or individual ants scattered around the yard.

However, this calculation gives us a good approximation of the number of ants in the yard based on the information given.

To estimate the total number of ants in Mrs. Brown's yard, we can add up the number of ants in each of the three ant hills:4,867,190 + 6,256,304 + 3,993,102 = 15,116,596.

The expression for Kp for the given equilibrium reaction is: Kp = (P(NO2))^2 / (P(NO))^2 * (P(O2))

To write the expression for Kp for the given equilibrium reaction, we need to use the equilibrium constant expression. In this case, the equilibrium constant is represented as Kp, which is the ratio of the partial pressures of the products to the partial pressures of the reactants, each raised to the power of their stoichiometric coefficient.

For the reaction 2NO(g) + O2(g) « 2NO2(g), the expression for Kp is:

Kp = (P(NO2))^2 / (P(NO))^2 * (P(O2))

Here, P(NO2) represents the partial pressure of NO2, P(NO) represents the partial pressure of NO, and P(O2) represents the partial pressure of O2.

So, to calculate Kp, we need the partial pressures of NO2, NO, and O2 at the given temperature of 1000 K.

However, the given information does not provide the partial pressures of the substances. It only provides the standard Gibbs free energy of formation (ΔG°f) values for NO2 and NO.
