1.8 raised to the seventh power divided by 1.8 raised to the sixth power is found as 3.24. So, the correct is option 3: 3.24.

To evaluate the expression 1.8 raised to the seventh power divided by 1.8 raised to the sixth power, all raised to the second power, we can use the property of exponents. When dividing two powers with the same base, we subtract the exponents.

So, 1.8 raised to the seventh power divided by 1.8 raised to the sixth power is equal to 1.8 to the power of (7-6), which simplifies to 1.8 to the power of 1.

Next, we raise the result to the second power. This means we multiply the exponent by 2.

Therefore, 1.8 raised to the seventh power divided by 1.8 raised to the sixth power, all raised to the second power is equal to 1.8 to the power of (1*2), which simplifies to 1.8 squared.

Calculating 1.8 squared, we get 3.24.

Statistics suggest that if a robbery remains unsolved for a specific period of time, it is highly unlikely to be solved according to available data.

Based on statistical analysis, there is a critical time frame within which the chances of solving a robbery are significantly higher. While the exact duration may vary depending on various factors such as the nature of the crime, available evidence, investigative resources, and the efficiency of law enforcement agencies, data suggests that the probability of solving a robbery declines as time progresses. This could be attributed to factors like fading memories of witnesses, loss of crucial evidence, or the diversion of investigative efforts to other cases. Consequently, prompt and diligent investigative work is crucial for increasing the likelihood of solving a robbery before it becomes increasingly difficult to resolve.

It will take approximately 6.235 seconds for the frisbee to hit the ground. we need to determine when the height, represented by the function h(t), is equal to zero.

The function h(t) = -0.145t^2 + 0.019t + 5.5 represents the height of the frisbee at time t.

To find when the frisbee hits the ground, we set h(t) = 0 and solve for t.

0 = -0.145t^2 + 0.019t + 5.5

Now we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula.

Using the quadratic formula, t = (-b ± √(b^2 - 4ac)) / (2a)

For this equation, a = -0.145, b = 0.019, and c = 5.5.

Plugging these values into the quadratic formula, we get:

t = (-0.019 ± √(0.019^2 - 4(-0.145)(5.5))) / (2(-0.145))

Simplifying this expression, we get:

t ≈ (-0.019 ± √(0.000361 + 3.18)) / (-0.29)

Now, we can calculate the value inside the square root:

t ≈ (-0.019 ± √(3.180361)) / (-0.29)

t ≈ (-0.019 ± 1.782) / (-0.29)

Simplifying further, we have two possible solutions:

t1 ≈ (-0.019 + 1.782) / (-0.29) ≈ 6.235 seconds

t2 ≈ (-0.019 - 1.782) / (-0.29) ≈ -6.199 seconds

Since time cannot be negative in this context, we disregard the negative solution.

The depth of the water is changing at a rate of 55/14 ft/min when the water is 11 ft high.

To find how fast the depth of the water in the conical tank changes, we can use related rates.

The volume of a cone is given by V = (1/3)πr²h,

where r is the radius and

h is the height.

We are given that the cone leaks water at a rate of 11 ft³/min.

This means that dV/dt = -11 ft³/min,

since the volume is decreasing.

To find how fast the depth of the water changes (dh/dt) when the water is 11 ft high, we need to find dh/dt.

Using similar triangles, we can relate the height and radius of the cone. Since the height of the cone is 14 ft and the radius is 5 ft, we have

r/h = 5/14.

Differentiating both sides with respect to time,

we get dr/dt * (1/h) + r * (dh/dt)/(h²) = 0.

Solving for dh/dt,

we find dh/dt = -(r/h) * (dr/dt)

= -(5/14) * (dr/dt).

The theorem "You can't add a word to a song" can be proved using the Russian saying "You can't take a word out of a song" through a proof by contradiction. By assuming that adding a word to a song is possible and showing that it contradicts the given hypothesis, we conclude that the theorem holds true.

To prove the theorem "You can't add a word to a song" based on the Russian saying "You can't take a word out of a song," we can translate these statements into logical propositions and use a proof technique known as proof by contradiction.

Let's define the following propositions:

P: "You can take a word out of a song."

Q: "You can add a word to a song."

According to the Russian saying, the hypothesis is that P is false, meaning it is not possible to take a word out of a song. We want to prove that the theorem, Q is false, meaning it is not possible to add a word to a song.

To prove this by contradiction, we assume the opposite of the theorem, which is Q is true (i.e., you can add a word to a song). We will then show that this assumption leads to a contradiction with the given hypothesis (P is false).

Assume Q is true: You can add a word to a song.

According to the hypothesis, P is false: You can't take a word out of a song.

If you can add a word to a song (Q is true) and you can't take a word out of a song (P is false), it implies that a song can have words added to it and none can be taken out.

However, this contradicts the original saying, which states that "You can't take a word out of a song."

Therefore, our assumption (Q is true) leads to a contradiction.

Consequently, Q must be false: You can't add a word to a song.

By proving the contradiction, we have demonstrated that the theorem "You can't add a word to a song" holds based on the hypothesis provided by the Russian saying "You can't take a word out of a song."

Given that the surface area decreases at a rate of [tex]2 cm^2/min[/tex], we can set up the equation dA/dt = -2, where dA/dt is the rate of change of the surface area over time.

To find the rate at which the diameter decreases, we need to find dR/dt, the rate of change of the radius over time.

Since r = d/2, where d is the diameter, we can substitute r = d/2 into the surface area equation to get A = 4π[tex](d/2)^2[/tex]= π[tex]d^2[/tex].

Differentiating both sides of the equation with respect to time, we get dA/dt = 2πd * (dd/dt).

Now, we can substitute the given values into the equation:

The company is considering an investment project that costs 8 million today and yields a payoff of 10 million in five years. To determine whether the project is a good investment, we need to calculate the net present value (NPV). The NPV takes into account the time value of money by discounting future cash flows to their present value.

1. Calculate the present value of the 10 million payoff in five years. To do this, we need to use a discount rate. Let's assume a discount rate of 5%.

PV = 10 million / (1 + 0.05)^5
PV = 10 million / 1.27628
PV ≈ 7.82 million

2. Calculate the NPV by subtracting the initial cost from the present value of the payoff.

NPV = PV - Initial cost
NPV = 7.82 million - 8 million
NPV ≈ -0.18 million

Based on the calculated NPV, the project has a negative value of approximately -0.18 million. This means that the project may not be a good investment, as the expected return is lower than the initial cost.

In conclusion, the main answer to whether the company should proceed with the investment project is that it may not be advisable, as the NPV is negative. The project does not seem to be financially viable as it is expected to result in a net loss.

To check whether the statement E[X^2]=4Var[X] is True or False for the given information, we need to recall the formulas of the expected value and variance of a Poisson distribution.

Equation of a Poisson distribution

P(X = k) = e^(-λ)*λ^(k)/k!, where k is the number of events in the given time interval, λ is the rate at which the events occur

Expected Value of a Poisson distribution:

E(X) = λ

Variance of a Poisson distribution:

Var(X) = λ

So, for a Poisson distribution, E(X^2) can be calculated as follows:

E(X^2) = λ + λ^2

Where, λ = average rate/ mean rate = 1/10 = 0.1

So, E(X^2) = 0.1 + 0.01 = 0.11

And Var(X) = λ = 0.1

Now, let's check whether the statement E[X^2]=4Var[X] is True or False

To calculate the 99% confidence interval for the mean amount of money this bank's customers keep in their checking accounts, we can use the formula:

Confidence interval = mean ± (critical value) * (standard deviation / √sample size)

First, we need to find the critical value for a 99% confidence level. Since the sample size is large (n > 30), we can assume the sampling distribution is approximately normal and use the Z-distribution.

The critical value for a 99% confidence level is approximately 2.576.

Next, we can substitute the values into the formula:

Confidence interval = $766 ± (2.576) * ($85 / √128)

Calculating the expression inside the parentheses:

$85 / √128 ≈ $7.51

Now, we can substitute this value into the formula:

Confidence interval = $766 ± (2.576) * ($7.51)

Calculating the expression inside the parentheses:

(2.576) * ($7.51) ≈ $19.33

Therefore, the 99% confidence interval for the mean amount of money this bank's customers keep in their checking accounts is approximately $766 ± $19.33, or between $746.67 and $785.33.

The probabilities for the given distribution are:

p(x < 0) = 0.49,

p(x ≤ 0) = 0.49,

p(x > 0) = 2.10,

p(x ≥ 0) = 2.38, and

p(x = 10) = 0.3.

To calculate the probabilities using the given probability distribution, we can use the PMF (Probability Mass Function) values provided:

x -10 -5 0 10 18 100

f(x) 0.01 0.2 0.28 0.3 0.8 1.00

a) To find p(x < 0), we need to sum the probabilities of all x-values that are less than 0. From the given PMF values, we have:

p(x < 0) = p(x = -10) + p(x = -5) + p(x = 0)

= 0.01 + 0.2 + 0.28

= 0.49

b) To find p(x ≤ 0), we need to sum the probabilities of all x-values that are less than or equal to 0. Using the PMF values, we have:

p(x ≤ 0) = p(x = -10) + p(x = -5) + p(x = 0)

= 0.01 + 0.2 + 0.28

= 0.49

c) To find p(x > 0), we need to sum the probabilities of all x-values that are greater than 0. Using the PMF values, we have:

p(x > 0) = p(x = 10) + p(x = 18) + p(x = 100)

= 0.3 + 0.8 + 1.00

= 2.10

d) To find p(x ≥ 0), we need to sum the probabilities of all x-values that are greater than or equal to 0. Using the PMF values, we have:

p(x ≥ 0) = p(x = 0) + p(x = 10) + p(x = 18) + p(x = 100)

= 0.28 + 0.3 + 0.8 + 1.00

= 2.38

e) To find p(x = 10), we can directly use the given PMF value for x = 10:

p(x = 10) = 0.3

In conclusion, we have calculated the requested probabilities using the given probability distribution.

p(x < 0) = 0.49,

p(x ≤ 0) = 0.49,

p(x > 0) = 2.10,

p(x ≥ 0) = 2.38, and

p(x = 10) = 0.3.

The function that generates the table of values on the right is (H) y = log₂x.

The function (H) y = log₂x represents the logarithm of x to the base 2. In this function, the base 2 logarithm is applied to the variable x, resulting in the corresponding values of y.

The table of values generated by this function will have x-values in the domain, and y-values representing the logarithm of each x-value to the base

2. The logarithm of a number to a given base is the exponent to which the base must be raised to obtain that number. In this case, the base 2 logarithm gives us the power to which 2 must be raised to produce the x-value.

For example, if we take x = 8, the base 2 logarithm of 8 is 3, since 2³ = 8. Similarly, for x = 4, the base 2 logarithm is 2, as 2² = 4. These values will be reflected in the table of values generated by the function (H) y = log₂x. Hence option H is the correct option.
