The child ticket costs $10 less than an adult ticket for the Reno Aces baseball game.

In the first scenario, the family paid $71 for 3 adult tickets and 5 children tickets. Let's assume the cost of an adult ticket is A and the cost of a child ticket is C. We can create an equation based on the given information:

3A + 5C = 71

In the second scenario, the family paid $31 for 2 adult tickets and 1 child's ticket. We can create a similar equation:

2A + C = 31

To find the difference in cost between an adult and a child ticket, we need to determine the values of A and C. We can solve these equations simultaneously to find the solution. Subtracting the second equation from the first equation eliminates the C term:

3A - 2A + 5C - C = 71 - 31

A + 4C = 40

Simplifying the equation, we get:

A = 40 - 4C

Substituting this value into the second equation:

2(40 - 4C) + C = 31

80 - 8C + C = 31

7C = 49

C = 7

Now that we have the value of C, we can substitute it back into the first equation to find A:

3A + 5(7) = 71

3A + 35 = 71

3A = 36

A = 12

Therefore, an adult ticket costs $12 and a child ticket costs $5. The child ticket is $10 less than an adult ticket.

we have:

P(X > 6) < 0.0668

We can use the standard normal distribution to find probabilities for a normal distribution with mean u and standard deviation 2. Let Z = (X - u)/2 be the standard normal variable corresponding to X.

(A) Since f(6) > f(16), we have P(X < 6) > P(X < 16). Using the standard normal distribution, we can write this as:

P(Z < (6 - u)/2) > P(Z < (16 - u)/2)

Multiplying both sides by -1 and using the symmetry of the standard normal distribution, we get:

P(Z > (u - 6)/2) < P(Z > (u - 16)/2)

Looking up the standard normal distribution table, we can find the values of the right-hand side probabilities for different values of the argument. For example, if we use a table with z-scores and look up the probability corresponding to z = 1.5, we find that P(Z > 1.5) = 0.0668 (rounded to four decimal places).

Therefore, we have:

The minimum growth rate you would require from this stock is 11.75%.

To determine the minimum growth rate you would require from this stock, you can use the dividend discount model. The dividend discount model is a method of valuing a stock based on the present value of its expected future dividends. In this case, the formula would be:

Expected Return = Dividend Yield + Growth Rate

where:

Dividend Yield = Annual Dividend / Stock Price

In this case, the annual dividend is $2.25 and the stock price is $53, so:

Dividend Yield = $2.25 / $53 = 0.0425 or 4.25%

You require a return of 16%, so:

Expected Return = 0.16

Substituting the values we have:

0.16 = 0.0425 + Growth Rate

Solving for Growth Rate:

Growth Rate = 0.16 - 0.0425 = 0.1175 or 11.75%

Therefore, the minimum growth rate you would require from this stock is 11.75%.

The transmitted intensity i1 is approximately 19.32 watts per square meter.

An indicator of a physical phenomenon's strength or power, such as light, sound, or radiation, is its intensity. It is often expressed in terms of the quantity of energy being transmitted or received per unit area or volume. For instance, the intensity of light is expressed in watts per square metre, while the strength of sound is expressed in watts per square metre per hertz. Distance, direction, and the qualities of the medium through which the phenomenon is transmitted can all have an impact on intensity.

To find the transmitted intensity (i1), we need to use the formula:

[tex]i1 = i0 * cos(θ0 - θta)[/tex]

where i0 is the initial intensity, [tex]θ0[/tex]is the initial angle, and [tex]θta[/tex] is the transmitted angle.

Step 1: Calculate the difference between the angles:
[tex]Δθ = θ0 - θta[/tex] = 25.0 degrees - 40.0 degrees = -15.0 degrees

Step 2: Convert the angle difference to radians:
[tex]Δθ[/tex](in radians) = -15.0 degrees *[tex](\pi /180)[/tex] ≈ -0.2618 radians

Step 3: Calculate the cosine of the angle difference:
[tex]cos(Δθ) ≈ cos(-0.2618)[/tex]≈ 0.9659

Step 4: Calculate the transmitted intensity (i1):
i1 = i0 * [tex]cos(Δθ)[/tex] = 20.0[tex]W/m^2[/tex] * 0.9659 ≈ 19.32 [tex]W/m^2[/tex]

The y-intercept is (0, 1). a. the end behavior of the graph is that it behaves like y = 2x + 1 for large values of |x|. b. the y-intercept of the graph of the function is y = 1.

(a) The end behavior of the graph of the function is that it behaves like y = 2x + 1 for large values of |x|.

To determine the end behavior, we look at the highest degree term in the polynomial function, which is x. The coefficient of this term is 2, which is positive. This tells us that as x becomes very large in either the positive or negative direction, the function will also become very large in the positive direction. Therefore, the end behavior of the graph is that it behaves like y = 2x + 1 for large values of |x|.

(b) To find the x-intercepts of the graph of the function, we set f(x) = 0 and solve for x:

(x+4)-(3-x) = 0

2x + 1 = 0

x = -1/2

Therefore, the x-intercept of the graph of the function is x = -1/2.

To find the y-intercept of the graph of the function, we set x = 0 and evaluate f(x):

In either case, G cannot have anti-parallel edges. Therefore, we have shown that if G is a DAG where all vertices are sources or sinks, or both, then G has neither self-loops nor anti-parallel edges.

Assume that G has a self-loop at vertex v. Then, there is an edge from v to v in E, which contradicts the definition of a source or a sink. Therefore, G cannot have self-loops.

Now, suppose that G has anti-parallel edges between vertices u and v, i.e., there are two edges (u, v) and (v, u) in E. Since all vertices in G are sources or sinks, there are two cases to consider:

Case 1: u and v are both sources. This means that there are no edges entering u or v, and both edges (u, v) and (v, u) must be oriented in the same direction. But then, there is a cycle in G, which contradicts the definition of a DAG.

Case 2: u and v are both sinks. This means that there are no edges leaving u or v, and both edges (u, v) and (v, u) must be oriented in the same direction. But then, there is a cycle in G, which contradicts the definition of a DAG.

The number of solutions in nonnegative integers of the inequality x1 x2 ··· xn ≤ m is c(m n, n), where c(a,b) denotes the binomial coefficient.

Let's define a new variable y_i = m - x_i for each i in {1, 2, ..., n}. Then we have the following equivalence:

x1 x2 ··· xn ≤ m <==> y1 y2 ··· yn ≥ (m+1)^n / (x1 x2 ··· xn)

Note that the right-hand side is a positive integer, since x1 x2 ··· xn divides (m+1)^n. Therefore, we are counting the number of solutions in positive integers y1, y2, ..., yn of the inequality y1 y2 ··· yn ≥ (m+1)^n / (x1 x2 ··· xn).

Now, using the stars and bars argument, we can count the number of solutions of the equation y1 y2 ··· yn = k, where k is a positive integer. The number of solutions is c(k-1, n-1), since we can place n-1 dividers among k-1 identical objects to partition them into n nonempty groups.

Therefore, the number of solutions of y1 y2 ··· yn ≥ (m+1)^n / (x1 x2 ··· xn) is:

sum(c(k-1, n-1), k=(m+1)^n / (x1 x2 ··· xn), infinity)

This sum can be simplified using the following identity:

sum(c(k-1, n-1), k=a, b) = c(b, n) - c(a-1, n)

Therefore, the number of solutions of x1 x2 ··· xn ≤ m is:

c((m+1)^n, n) - sum(c((m+1)^n / x1 x2 ··· xn - 1, n), x1, x2, ..., xn >= 1)

The second sum can be seen as a summation over all divisors of (m+1)^n. Therefore, we have:

c((m+1)^n, n) - sum(c(d-1, n), d| (m+1)^n)

Using the multiplicativity of the divisor function and the binomial coefficient, we can simplify this to:

c(m n, n)

P(A) = P(A | B) * P(B) + P(A | B') * P(B'), where B' is the complement of B

* Plugging in the given values, we get P(A) = 0.45 * 0.30 + P(A | B') * 0.70. We don't know P(A | B'), but we know that P(A) must add up to 1, so we can solve for it:

P(A) = 0.45 * 0.30 + P(A | B') * 0.70 = 1 - P(A' | B') * 0.70, where A' is the complement of A.

* We can then solve for P(A' | B') using the formula P(A' | B') = (1 - P(A)) / 0.70 = (1 - 0.65) / 0.70 = 0.21. Plugging this back into the formula for P(A), we get P(A) = 0.45 * 0.30 + 0.21 * 0.70 = 0.255. Finally, we can plug in all the values we've calculated to get"

k = [tex]\frac{5}{72}[/tex]

Answer: k=8.4 or 42/5

Step-by-step explanation: to find k you take 1 2/5 and divide it by 1/6. When I did it I got 8.4. To check my work I replaced the variable in the equation and it was correct.

a. the probability of only drawing balls with odd numbers is 5/210 = 1/42. b. the probability that the smallest drawn number is equal to k is (10-k+1 choose 4) / (10 choose 4) for k = 1,...,10.

(a) The probability of only drawing balls with odd numbers can be found by counting the number of ways to select four odd-numbered balls divided by the total number of ways to select four balls from the urn without replacement. There are 5 odd-numbered balls in the urn, so the number of ways to select four of them is (5 choose 4) = 5. The total number of ways to select four balls from the urn without replacement is (10 choose 4) = 210. Therefore, the probability of only drawing balls with odd numbers is 5/210 = 1/42.

(b) To find the probability that the smallest drawn number is equal to k for k = 1,...,10, we need to count the number of ways to select four balls from the remaining balls after the k-1 smallest balls have been removed, and divide by the total number of ways to select four balls from the urn without replacement. The number of ways to select four balls from the remaining (10-k+1) balls is (10-k+1 choose 4), and the total number of ways to select four balls from the urn without replacement is (10 choose 4). Therefore, the probability that the smallest drawn number is equal to k is (10-k+1 choose 4) / (10 choose 4) for k = 1,...,10.

The x-component of the vector ⃗ is -9.98 and the y-component is 8.53.

We can find the x and y components of the vector ⃗ by using trigonometry. The magnitude of the vector is given as 13.1, and the direction of the vector is 50∘ counter-clockwise from the -axis. We can use the cosine and sine functions to find the x and y components, respectively.

cos(50∘) = -0.6428, sin(50∘) = 0.7660

x-component = magnitude x cos(50∘) = 13.1 x (-0.6428) = -9.98

y-component = magnitude x sin(50∘) = 13.1 x (0.7660) = 8.53

Therefore, the x-component of the vector ⃗ is -9.98, and the y-component is 8.53.

The x-component of the vector is approximately 8.375 and the y-component is approximately 9.955.

To find the x- and y-components of the vector, we can use trigonometry.

Given that the magnitude of the vector is 13.1 and the direction is 50° counter-clockwise from the - axis, we can determine the x- and y-components as follows:

The x-component (horizontal component) can be found using the formula:

x = magnitude * cos(angle)

x = 13.1 * cos(50°)

x ≈ 8.375

The y-component (vertical component) can be found using the formula:

y = magnitude * sin(angle)

y = 13.1 * sin(50°)

The formula for the indicated rate of change dc/dk is dc/dk = 32c.

To find the indicated rate of change, we need to calculate dc/dk, which represents the partial derivative of the function s(c, k) = c(32k) with respect to k while treating c as a constant.

To calculate dc/dk, we differentiate the function s(c, k) with respect to k while considering c as a constant:

dc/dk = d/dk (c * (32k))

Applying the product rule of differentiation, we have:

dc/dk = c * d/dk (32k) + (32k) * d/dk (c)

The derivative of 32k with respect to k is 32, as it is a constant multiple of k. The derivative of c with respect to k is zero since c is treated as a constant.

Therefore, dc/dk simplifies to:

dc/dk = c * 32 + 0

dc/dk = 32c

So, the formula for the indicated rate of change dc/dk is dc/dk = 32c.

The probability density function (PDF) of Z, where Z = max{X, Y} and X and Y are independent random variables uniformly distributed on the interval [0, 1].

1. First, we need to find the cumulative distribution function (CDF) of Z, which is given by P(Z ≤ z). Since X and Y are independent, we can write this as P(max{X, Y} ≤ z) = P(X ≤ z and Y ≤ z).

2. As X and Y are uniformly distributed on [0, 1], their individual CDFs are given by P(X ≤ x) = x and P(Y ≤ y) = y for x, y ∈ [0, 1].

3. Since X and Y are independent, we can multiply their CDFs to find the joint CDF of Z: P(Z ≤ z) = P(X ≤ z) * P(Y ≤ z) = z * z = z^2 for z ∈ [0, 1].

4. Finally, to find the PDF of Z, we take the derivative of the CDF with respect to z:

f_Z(z) = d/dz (z^2) = 2z for z ∈ [0, 1].

So, the probability density function PDF of Z, where Z = max{X, Y} and X and Y are independent random variables uniformly distributed on the interval [0, 1], is f_Z(z) = 2z for z ∈ [0, 1].

The correct option is D) 3/2. Given that the equation 3x + 2y = 0 represents a proportional relationship, we need to find the constant of proportionality.

Constant of proportionality is defined as the ratio between two proportional quantities. To determine the constant of proportionality in the equation 3x - 2y = 0, we need to rearrange the equation to the form y = kx, where k represents the constant of proportionality.

Starting with the given equation:

3x - 2y = 0

Let's isolate y:

2y = 3x

Divide both sides by 2:

y = (3/2)x

Comparing this equation with the form y = kx, we can see that the constant of proportionality (k) is (3/2).

Therefore, the constant of proportionality in the equation 3x - 2y = 0 is (3/2), and
