To solve this problem, let's assume that the number of children admitted is "x" and the number of adults admitted is "y".

Given that the admission fee for children is $1.50 and the admission fee for adults is $4, we can set up the following equations:

1.50x + 4y = 864 (equation 1)
x + y = 326 (equation 2)

To solve this system of equations, we can use the method of substitution.

From equation 2, we can express x in terms of y:
x = 326 - y

Substituting this value of x into equation 1, we get:

1.50(326 - y) + 4y = 864
489 - 1.50y + 4y = 864
2.50y = 375
y = 150

Now, substitute the value of y back into equation 2 to find x:

x + 150 = 326

The proof of the Supplement Theorem can be stated as follows: If two angles are supplementary to the same angle (or to congruent angles), then the two angles are congruent.

The Supplement Theorem states that if two angles are supplementary to the same angle (or to congruent angles), then the two angles are congruent.

To prove this theorem, we can use the following steps:

Let's assume we have two angles, angle A and angle B, which are both supplementary to angle C.

By definition, supplementary angles add up to 180 degrees.

So, we can express this as:

angle A + angle C = 180 degrees (equation 1)

angle B + angle C = 180 degrees (equation 2)

We want to prove that angle A is congruent to angle B, so we need to show that angle A = angle B.

To do that, we can subtract equation 2 from equation 1:

(angle A + angle C) - (angle B + angle C) = 180 degrees - 180 degrees

angle A - angle B = 0 degrees

angle A = angle B

Hence, we have shown that if two angles are supplementary to the same angle (or to congruent angles), then the two angles are congruent.

Therefore, the Supplement Theorem is proven.

This proof relies on the fact that if two expressions are equal to the same value, subtracting one from the other will result in zero.

In this case, subtracting the two equations shows that the difference between angle A and angle B is zero, implying that they are congruent.

The probability that the target is hit at least twice, when ten shots are fired independently with a probability of hitting the target of 1/5, is approximately 0.737.

To find the probability that the target is hit at least twice, we need to calculate the probability of hitting the target exactly twice, exactly three times, and so on, up to exactly ten times, and then sum up these probabilities.

Let's use the binomial probability formula to calculate the probabilities of hitting the target a specific number of times:

[tex]P(X = k) = C(n, k) * p^k * {1 - p}^{n - k}[/tex]

Where:

P(X = k) is the probability of hitting the target exactly k times,

n is the total number of shots fired (in this case, 10),

k is the specific number of hits (from 2 to 10),

p is the probability of hitting the target in a single shot (1/5), and

C(n, k) represents the binomial coefficient (n choose k).

Let's calculate the probabilities for k = 2, 3, 4, ..., 10 and sum them up:

P(hit at least twice) = P(X ≥ 2) = P(X = 2) + P(X = 3) + ... + P(X = 10)

[tex]P(X = k) = C(10, k) * (1/5)^k * (4/5)^{10 - k}[/tex]

Using this formula, we can calculate the probabilities for each value of k and sum them up:

P(X ≥ 2) = P(X = 2) + P(X = 3) + ... + P(X = 10)

P(X ≥ 2) ≈ 0.037 + 0.122 + 0.233 + 0.267 + 0.201 + 0.106 + 0.038 + 0.009 + 0.001 + 0.000

P(X ≥ 2) ≈ 0.737

The probability that the first claim from a good driver will be filed within 3 years and the first claim from a bad driver will be filed within 2 years can be calculated using the concept of independent exponential distributions.

To find the probability, we can use the formula for the probability density function (PDF) of the exponential distribution, which is given by:

f(x) = λ * e^(-λx)

where λ is the rate parameter, and e is the base of the natural logarithm.

In this case, the mean waiting time for the first claim from a good driver is 6 years, which means the rate parameter for the exponential distribution is λ = 1/6. Similarly, the mean waiting time for the first claim from a bad driver is 3 years, so the rate parameter for that exponential distribution is λ = 1/3.

To calculate the probability that the first claim from a good driver will be filed within 3 years, we need to find the cumulative distribution function (CDF) of the exponential distribution. The CDF gives us the probability that the waiting time is less than or equal to a given value.

The CDF for the exponential distribution is given by:

F(x) = 1 - e^(-λx)

Substituting the values, we get:

F(3) = 1 - e^(-1/6 * 3)
     = 1 - e^(-1/2)
     = 1 - 0.6065
     = 0.3935

So the probability that the first claim from a good driver will be filed within 3 years is 0.3935.

Similarly, to calculate the probability that the first claim from a bad driver will be filed within 2 years, we can use the CDF of the exponential distribution with a rate parameter of 1/3:

F(2) = 1 - e^(-1/3 * 2)
     = 1 - e^(-2/3)
     ≈ 0.4866

So the probability that the first claim from a bad driver will be filed within 2 years is approximately 0.4866.

To find the probability that both events occur, we can multiply the probabilities:

P(both events occur) = P(first claim from good driver within 3 years) * P(first claim from bad driver within 2 years)
                    = 0.3935 * 0.4866
                    ≈ 0.1912

Therefore, the probability that the first claim from a good driver will be filed within 3 years and the first claim from a bad driver will be filed within 2 years is approximately 0.1912.

The probability that the first claim from a good driver will be filed within 3 years and the first claim from a bad driver will be filed within 2 years is approximately 0.1912. This probability is obtained by multiplying the individual probabilities of each event occurring.

Sixteen randomly selected engines were tested, and their maximum horsepower values are provided. Assuming the data is normally distributed and using a significance level of 0.05, the test statistic is computed to assess the hypothesis.

To perform the hypothesis test, we will use a t-test for the mean. The null hypothesis (H0) assumes that the average maximum horsepower for the experimental engines is equal to the calculated maximum horsepower of 630HP. The alternative hypothesis (Ha) assumes that the average maximum horsepower is significantly different from 630HP.

Using the provided data, we calculate the sample mean of the maximum horsepower values:

(643 + 641 + 598 + 621 + 644 + 601 + 649 + 652 + 671 + 653 + 666 + 654 + 670 + 670 + 666 + 654) / 16 = 651.0625

Next, we calculate the sample standard deviation to estimate the population standard deviation:

s = √[((643 - 651.0625)^2 + (641 - 651.0625)^2 + ... + (654 - 651.0625)^2) / (16 - 1)] ≈ 24.663

Using the formula for the t-test statistic:

t = (sample mean - hypothesized mean) / (sample standard deviation / √sample size)

t = (651.0625 - 630) / (24.663 / √16) ≈ 2.027

Finally, comparing the calculated t-value of 2.027 with the critical t-value at a significance level of 0.05 (using a t-distribution table or software), we determine whether to reject or fail to reject the null hypothesis. If the calculated t-value falls outside the critical region, we reject the null hypothesis and conclude that there is a significant difference between the average maximum horsepower and the calculated maximum horsepower.

Given that the new mean is 11 and the value of the new point is 100, we can write the equation as follows:

11 = (Sum of all values + 100) / (n + 1)

Next, we can simplify the equation by multiplying both sides by (n + 1):

11(n + 1) = Sum of all values + 100

Expanding the left side:

11n + 11 = Sum of all values + 100

Since the original mean was 10, the sum of all values is equal to 10n:

11n + 11 = 10n + 100

Subtracting 10n from both sides:

n + 11 = 100

Subtracting 11 from both sides:

n = 89

Therefore, the original data set consisted of 89 points.

Rihanna will walk next year if she walks for 7 hours at the same speed, we need to know her walking speed. Let's assume her walking speed is 3 miles per hour.

To find the total distance, we can multiply the speed (3 miles per hour) by the time (7 hours):
3 miles/hour × 7 hours = 21 miles
Therefore, if Rihanna walks for 7 hours at the same speed next year, she will walk 21 miles.
It's important to note that this calculation assumes Rihanna maintains a consistent walking speed throughout the entire duration of 7 hours. If her speed changes, the total distance she covers would be different.

Remember, this answer is based on the assumption that Rihanna walks at a speed of 3 miles per hour. If her walking speed is different, the result would change accordingly.

The measure of this angle is equal to half the measure of the intercepted arc. ASG angles that intercept the same arc are congruent, and they are always less than or equal to 180 degrees.

When two chords intersect inside a circle, an angle is formed. The ASG angle is a type of angle formed by two chords that intersect within a circle. This angle is also known as an inscribed angle or central angle. Let's go over some important concepts related to this type of angle and explore some of its properties.
An inscribed angle is an angle that forms when two chords intersect within a circle. In particular, the angle is formed by the endpoints of the chords and a point on the circle. The measure of an inscribed angle is equal to half the measure of the intercepted arc. Therefore, we can find the measure of an ASG angle if we know the measure of the arc that it intercepts.
A central angle is another type of angle that forms when two chords intersect within a circle. This angle is formed by the endpoints of the chords and the center of the circle. The measure of a central angle is equal to the measure of the intercepted arc. This means that if we know the measure of a central angle, we can also find the measure of the intercepted arc.
One important property of ASG angles is that they are congruent if they intercept the same arc. This means that if we have two ASG angles that intercept the same arc, then the angles are equal in measure.

Another important property of ASG angles is that they are always less than or equal to 180 degrees. This is because the arc that they intercept cannot be larger than half the circumference of the circle.

There are 70 different ways to choose 4 classes from a pool of 8 available classes for the next quarter.

To determine the number of ways you can choose 4 classes from a pool of 8 available classes for the next quarter, we can use the concept of combinations.

The formula to calculate combinations is given by nCr = n! / (r! * (n-r)!), where n is the total number of options and r is the number of choices we want to make.

In this case, we have 8 classes to choose from, and we want to select 4 classes. Applying the formula, we get:

8C4 = 8! / (4! * (8-4)!) = 8! / (4! * 4!) = (8 * 7 * 6 * 5) / (4 * 3 * 2 * 1) = 70.

Therefore, there are 70 different ways to choose 4 classes from a pool of 8 available classes for the next quarter.

The student can buy the most of her favorite soft drink at store A, where she can purchase a maximum of 15 bottles within her budget.

To determine which store the student can buy the most of her favorite soft drink for no more than $20, let's compare the options at store A and store B.

At store A, the price of a 2-liter bottle is $1.29 (plus a 10-cent deposit).
To find out how many bottles the student can buy for $20, we divide $20 by the cost per bottle:

$20 / ($1.29 + $0.10) = 15.50 bottles.
However, since we cannot buy a fraction of a bottle, the student can only buy a maximum of 15 bottles.

At store B, the price of a 12-pack of 12 fl oz cans is $2.99 (plus a 5-cent deposit per can).
To find out how many 12-packs the student can buy for $20, we divide $20 by the cost per 12-pack: $20 / ($2.99 + ($0.05 * 12)) = 6.49 12-packs.
Again, since we cannot buy a fraction of a 12-pack, the student can only buy a maximum of 6 12-packs.

Therefore, the student can buy the most of her favorite soft drink at store A, where she can purchase a maximum of 15 bottles within her budget.

For every $1 invested over the next year, you can earn a profit of can$0.006 through covered interest arbitrage.

To determine the profit from covered interest arbitrage, we need to compare the returns from investing in Canada versus the returns from investing in the US. Covered interest arbitrage involves borrowing money at the lower interest rate and converting it into the currency with the higher interest rate.

First, let's calculate the profit in Canadian dollars. The one-year forward rate of can$1.2745 tells us that $1 will be worth can$1.2745 in one year. Therefore, by investing $1 in Canada at the risk-free rate of 4.8%, we will have can$1.048 after one year (can$1 * (1 + 0.048)).

Now, let's calculate the profit in US dollars. By investing $1 in the US at the risk-free rate of 4.2%, we will have $1.042 after one year ($1 * (1 + 0.042)).

The difference between the Canadian dollar profit and the US dollar profit is can$1.048 - $1.042 = can$0.006.

The area is 28 square feet.

The formula to find the area of a trapezoid is (base1 + base2) * height / 2. In this case, the base lengths are 6 feet and 8 feet, and the height is 4 feet. So, we can substitute these values into the formula.

Using the formula, we get:
Area = (6 + 8) * 4 / 2
      = 14 * 4 / 2
      = 56 / 2
      = 28 square feet

Therefore, the area of the trapezoidal tabletop is 28 square feet.

A trapezoid is a quadrilateral with one pair of parallel sides. The bases of a trapezoid are the parallel sides, and the height is the perpendicular distance between the bases. To find the area of a trapezoid, we multiply the sum of the bases by the height, and then divide by 2.

In this case, the sum of the bases is 6 + 8 = 14. Multiplying 14 by the height of 4 gives us 56. Dividing 56 by 2 gives us the final answer of 28 square feet.
