So total cost of movie is 14x1.55=$21.7

The cost of Planetarium is 1.05 and the number of students is 7

7x1.05=$7.35

4x1.10=$4.4

Add 21.7+7.35+4.4=33.45

The total cost is 33.45

As there are 1200 students

Now multiply 33.45 by 1200

33.45x1200=1,605.6

Hence, $1605.6 should the school expect to spend on all the activities

Answer:

B

Step-by-step explanation:

Here, we want to select an option that represents y as a function of x

We simply want to select an option which is a function

Now, the answer in this case is one in which there are no repeating values of x and y

What this means is that all x values and all y values exactly have a single relationship between each of them

No y values has two x values and no x values links to 2 y-values

With this in mind, the correct answer is ;

We can conclude that (fn) = x, for all n E N and x E [0, 1] converges uniformly to f(x) = x on [0, 1].

Given, fn(x) = x, for all n E N and x E [0, 1].Now, we need to prove that (fn) does not converge uniformly.Using the epsilon criteria, we need to show that there exists ε > 0 such that |fn(x) - f(x)| > ε for some x E [0, 1].Let ε = 1/2. Now, we have:|fn(x) - f(x)| = |x - x| = 0, for all x E [0, 1].Therefore, |fn(x) - f(x)| < 1/2, for all x E [0, 1].So, we conclude that (fn) converges uniformly to f(x) = x on [0, 1].

We have given that (fn) = x, for all n E N and x E [0, 1].

Now, we have to prove that (fn) does not converge uniformly using the epsilon criteria |fn(x) - f(x)| < ε for all x in [0, 1] and ε > 0.

Using the epsilon criteria, we need to show that there exists ε > 0 such that |fn(x) - f(x)| > ε for some x E [0, 1].Let ε = 1/2. Now, we have:|fn(x) - f(x)| = |x - x| = 0, for all x E [0, 1].

Therefore, |fn(x) - f(x)| < 1/2, for all x E [0, 1].So, we can say that (fn) converges uniformly to f(x) = x on [0, 1].

Therefore, we can conclude that (fn) = x, for all n E N and x E [0, 1] converges uniformly to f(x) = x on [0, 1].

The quadratic equation is decreasing on the interval (3, ∞).

Here we have the quadratic function:

y = 8 - (x - 3)^2

Remember that the quadratic equation in the vertex form can be written as:

y = a*(x - h)^2 + k

Then in this case the vertex is at (3, 8).

And we can see that the leading coefficient is -1, then the vertex is a maximum and after that the function starts decreasing.

Thus, the function decreases on the interval (3, ∞).

The explicit formula for f^-1 is (x-3)^(1/4) and this is obtained by switching the roles of x and y and solving for y in terms of x.

To find the inverse function of f(x)=x^4+3, we need to switch the roles of x and y, and solve for y.
Let y = x^4+3
Subtract 3 from both sides to get:
y - 3 = x^4
Take the fourth root of both sides to isolate x:
(x^4)^(1/4) = (y-3)^(1/4)
Simplify:
x = (y-3)^(1/4)
So the inverse function of f(x) is:
f^-1 (x) = (x-3)^(1/4)
This is the explicit formula for the inverse function of f(x).

Andrew drew a blue tile 50 times out of a total of 60 experiments. To determine if Andrew did something wrong, consider the probability of drawing a blue tile in each experiment.

The probability of drawing a blue tile can be calculated by dividing the number of blue tiles by the total number of tiles: probability of blue = 25 / (45 + 25 + 30) = 25 / 100 = 1/4. Since the probability of drawing a blue tile is 1/4, we would expect Andrew to draw a blue tile approximately 1/4 of the time in each experiment. Out of 60 experiments, we would expect him to draw a blue tile around 60 * (1/4) = 15 times on average. However, Andrew drew a blue tile 50 times, which is significantly higher than the expected average of 15 times. This suggests that Andrew's results deviate from the expected probability, indicating that something may have been done incorrectly. It is possible that Andrew did not conduct the experiments randomly or that there was an issue with the bag of tiles.

Further investigation is needed to determine the cause of the deviation and whether Andrew's results are valid.

The probability of selection of diagonal which is not shortest nor longest is 13/17.

We know very well that Icosagon has 20 sides.

If any diagonal is possible, it can be possible by connecting two points, so to choose r objects from n objects can be done by ⁿ \(C_{r}\) = \(\frac{n!}{r! (n-r)!}\)

So, number of ways to choose diagonal = \(^2^0C_{2}\)

After that we need to subtract 20 ways as single point can lead to diagonal making.

So, total number of ways to choose 20 diagonals =  170

Now, talking about the shorter diagonal

so, shorter diagonal =Diagonal connecting(A₁A₃, A₂A₄,.....) =20 diagonals.

Now, talking about longer diagonal=Diagonal connecting(A₁A₈,A₂A₉.........) = 20 diagonals

So, we have total chances of ⁿ \(C_{r}\) = \(\frac{n!}{r! (n-r)!}\) and possible number of chances of selection of shorter and longer diagonal

So, according to the formula,

Probability= Favorable outcome /Total outcome

Probability = [(Total ways to select diagonals - (Ways to select shorter diagonal) - Ways to select longer diagonal)]/(Total number of ways)

Probability = (170-20-20)/170

Probability = 130/170

Probability = 13/17

Hence, the probability of selecting a  diagonal such that it is not shortest nor longest is 13/17.

If the null hypothesis were correct, there would be a 0.47 percent chance of getting a sample proportion that deviates from the population proportion's hypothesised value

Proportion refers to the relationship between two quantities or numbers, indicating how they are related to each other in size or amount.

The best interpretation of a Z score of 0.47 for a sample proportion is:

b. If the null hypothesis were correct, there would be a 0.47 percent chance of getting a sample proportion that deviates from the population proportion's hypothesised value.

This interpretation is in line with the definition of a Z score, which is a measure of how many standard deviations a sample statistic (in this case, the sample proportion) is not what would be anticipated if the null hypothesis were true. A Z score of 0.47 means that the sample proportion is 0.47 standard deviations away from the expected value under the null hypothesis. Therefore, the interpretation that the probability of obtaining a sample proportion as far or farther than observed from the hypothesized value of the population proportion is 0.47, assuming the null hypothesis is true, is the most appropriate.

1. If the NPV is positive, then Jamie should install the aluminum siding.

2. If the present value of the painting cost is lower than the cost of installing aluminum siding (£2,600), then Jamie should choose the new paint option.

To determine whether Jamie should install aluminum siding in each scenario, we need to compare the costs and benefits involved.

1. Installing Aluminum Siding:

The cost of installing aluminum siding is £2,600, and it eliminates the need for annual painting, saving £500 per year. Additionally, Jamie believes it will increase the resale value of the house by no more than £400 after 4 years.

To assess whether Jamie should install aluminum siding, we can calculate the net present value (NPV) of the investment. Since Jamie can get a 6 percent interest rate on alternative investments, we'll use that as the discount rate.

NPV = Present Value of Benefits - Present Value of Costs

Costs:

- Initial cost of installing aluminum siding: £2,600

Benefits:

- Annual savings on painting cost: £500

- Increased resale value after 4 years: £400

To calculate the NPV, we need to discount the future benefits and costs back to their present values. Let's use the formula:

Present Value = Future Value / (1 + Discount Rate)^(Number of Years)

Discounted Costs:

Present Value of initial cost = £2,60

Discounted Benefits:

Present Value of annual savings = £500 /\((1 + 0.06)^4\)

Present Value of increased resale value = £400 / (1 + 0.06)^4

Now, let's calculate the NPV:

NPV = Present Value of benefits - Present Value of costs

    = (Present Value of annual savings + Present Value of increased resale value) - Present Value of initial cost

If the NPV is positive, then Jamie should install the aluminum siding.

2. New Paint Option:

In this scenario, the cost of painting every year with the new paint is £750. We need to compare this cost with the cost of installing aluminum siding (£2,600).

Since the painting cost occurs annually, we can use the same discount rate of 6 percent to calculate the present value of costs over 4 years:

Present Value of painting cost = \((£750 / 2) / (1 + 0.06)^4\)

If the present value of the painting cost is lower than the cost of installing aluminum siding (£2,600), then Jamie should choose the new paint option.
