There were 682 children's and 332 adults were admitted when the entrance charge to an park is $4 for adults and $1.50 for children.

Given that,

The entrance charge to an amusement park is $4 for adults and $1.50 for children. 351 persons visited the park on one particular day, and 1014 dollars in entrance fees were collected.

We have to find how many people and kids were allowed inside.

We know that,

We get equations as,

1.5x+4y=351 ----->equation(1)

The other equation is

x+y=1014 ----->equation(2)

Take the equation(2)

x+y=1014

y=1014-x

Substitute y=1014-x in equation(1)

1.5x+4y=351

1.5x+4(1014-x)=351

1.5x+2056-4x=351

1.5x-4x=351-2056

-2.5x=-1705

2.5x=1705

x=1705/2.5

x=682

Substitute x=682 in equation(2)

y=1014-x

y=1014-682

y=332

Therefore, There were 682 children's and 332 adults were admitted when the entrance charge to an amusement park is $4 for adults and $1.50 for children.

Therefore, the water balloon will be on the fourth story in one more second.

The acceleration due to gravity is approximately 9.8 m/s^2. Since the water balloon falls one story down (which is approximately 6 meters) in one second, we can calculate its initial velocity using the equation: d = 1/2at^2. Plugging in the values, we get: 6 = 1/2(9.8)t^2, which simplifies to t = sqrt(1.2245) ≈ 1.11 seconds. Therefore, in one more second, the water balloon will have fallen another story down, i.e., it will be on the fourth story.
The water balloon dropped by the bored college student falls one story down from the top in one second. To calculate how long it will take for it to fall another story down, we can use the equation: d = 1/2at^2, where d is the distance, a is the acceleration due to gravity, and t is time. Plugging in the values, we get t = sqrt(1.2245) ≈ 1.11 seconds.

The value of the variable n in the given equation, (3ⁿ⁻²) / (9¹⁻ⁿ) = 9, is 2

From the question, we are to solve the given equation for the given variable n.

The given equation is

(3ⁿ⁻²) / (9¹⁻ⁿ) = 9

To solve the equation, we will determine the value of n

First multiply both sides of the equation by (9¹⁻ⁿ)

(9¹⁻ⁿ) × (3ⁿ⁻²) / (9¹⁻ⁿ) = 9 × (9¹⁻ⁿ)

(3ⁿ⁻²) = 9 × (9¹⁻ⁿ)

3ⁿ⁻² = 9 × 9¹⁻ⁿ

Applying the multiplication law of indices

3ⁿ⁻² = 9¹⁺¹⁻ⁿ

3ⁿ⁻² = 9²⁻ⁿ

Express 9 as an exponent

3ⁿ⁻² = 3²⁽²⁻ⁿ⁾

since the bases are equal, equate the exponents

n - 2 = 2(2 - n)

Distribute 2 on the right side of the equation

n - 2 = 4 - 2n

n + 2n = 4 + 2

3n = 6

Divide both sides by 3

3n/3 = 6/3

n = 2

Hence, the value of n is 2

The probability that the student makes it to the second class before it starts is very close to 0.

To find the probability that the student makes it to the second class before it starts, we can use the concept of linear combinations of random variables and the properties of normal distributions.

Let's define the random variable X as the total time it takes for the student to transition from the end of the first class to the start of the second class. Since X is a linear combination of independent normally distributed random variables (X1, X2, X3), we can use their means and variances to calculate the mean and variance of X.

The mean of X is the sum of the means of X1, X2, and X3:

μX = μ1 + μ2 + μ3 = 9:02 + 9:15 + 10 = 28:17 minutes.

The variance of X is the sum of the variances of X1, X2, and X3:

σX^2 = σ1^2 + σ2^2 + σ3^2 = (2.5)^2 + (3)^2 + (2.5)^2 = 15.25 minutes^2.

Now, we need to calculate the probability that X is less than or equal to 0, meaning the student arrives before the second lecture starts. Since X follows a normal distribution, we can standardize the variable and calculate the probability using the standard normal distribution table.

Z = (0 - μX) / σX = (0 - 28:17) / √15.25 ≈ -9.43.

Using the standard normal distribution table or a calculator, we can find the probability corresponding to Z = -9.43. The probability is essentially 0, as the value is significantly far in the left tail of the standard normal distribution.

Therefore, the probability that the student makes it to the second class before it starts is very close to 0.

Answer: \(\frac{7}{8}\) or 0.875 in decimal form.

Step-by-step explanation:

Okay, so to solve this, the easiest method is to find a common denominator. While we could try using trial and error or if you know your tables really well, I don't so we will just multiply the denominators which is 8 and 4. We then multiply 8 and 4 which is 32.

To convert the fractions we have, we multiply both the numerator and denominator of each, by the multiple that multiplies the denominator to 32.

\(\frac{2}{4}\) multiply both 4 and 2 by 8. Now we have \(\frac{16}{32}\).

Same thing with the second number. We have \(\frac{3}{8}\). We multiply both the numerator and the denominator by 4. 3*4 is 12, 8*4 is 32.

Now we have \(\frac{12}{32}\).

Now that both fractions have common denominators, we can add the numerators. \(\frac{16}{32} +\frac{12}{32} = \frac{28}{32}\)

Now we have the answer, \(\frac{28}{32}\), but is that it?

No. Now to find the final two answers, we simply \(\frac{28}{32}\).

To simplify, we find the Greatest Common Factor of 28 and 32, which in this case happens to be 4. This is the highest number that either of those can be divided by to provide a normal whole number

After solving \(\frac{28/4}{32/4} =\frac{7}{8}\)

That is our final answer. \(\frac{7}{8}\).

If necessary, you can convert it to decimal form through simple division and end up with 0.875.

The probability that the average size of the fish you caught is more than 13 inches is approximately 0.0918, or about 9.18%.

We can use the Central Limit Theorem to approximate the distribution of the sample mean. According to the theorem, the sample mean of a sufficiently large sample will be approximately normally distributed with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

In this case, we have a sample size of 4, which may not be considered sufficiently large, but we can still use the approximation. Thus, the distribution of the sample mean can be approximated as:

mean = 11

standard deviation = 3 / sqrt(4) = 1.5

To find the probability that the average size of the fish you caught is more than 13 inches, we need to standardize the sample mean using the z-score formula:

z = (x - mean) / standard deviation

where x is the sample mean we want to find the probability for. Plugging in the values, we get:

z = (13 - 11) / 1.5 = 1.33

Now, we need to find the probability of getting a z-score greater than 1.33 in a standard normal distribution table or calculator. Using a calculator or statistical software, we find that this probability is approximately 0.0918.

Therefore, the probability that the average size of the fish you caught is more than 13 inches is approximately 0.0918, or about 9.18%.

Length of Bridge = 7.26 metres

Distance between the 2 people = 26.04 metres

The figure is attached below, to give you a clearer idea of the situation of the bridge and the 2 people.

Distance between Q and the bridge = 25m

Angle = 73.8°

Since P is located on the bridge (south-east corner), we can find the length of the bridge using tan 73.8°.

tan θ = height/base

tan 73.8° = 25/length of bridge

Let length of bridge =x.

⇒ 3.442 = 25/x

⇒ x = 25/3.442 = 7.2632 ≅ 7.26 metres.

To find the distance between P and Q (the 2 people), we can use sin 73.8°.

sin θ = height/hypotenuse

sin 73.8° = 25/distance between P and Q

Let distance between P and Q = y

sin 73.8° = 25/y

⇒ 0.96 = 25/y

⇒ y = 25/0.96 = 26.04166 ≅ 26.04 metres

Therefore, the distance between the 2 people = 26.04 metres, and the length of the bridge over the river = 7.26 metres.
