a. The mean and standard deviation of the sampling distribution of the difference in sample means xF - xM are 1.5 and 1.65 minutes.

b. The probability of getting a difference in sample means xF - xM that is less than 0 is approximately 0.20

What is Probability?

Probability is a field of mathematics that calculates the likelihood of an experiment occurring. We can know everything from the chance of getting heads or tails in a coin to the possibility of inaccuracy in study by using probability.

a. The mean of the sampling distribution of the difference in sample means, xF - xM, is equal to the difference of the population means, μF - μM = 8.8 - 7.3 = 1.5 minutes.

where σF and σM are the standard deviations of the populations of female and male students, respectively, and nF and nM are the sample sizes of female and male students, respectively.

\(Standard\ Deviation = \sqrt{3.3^2/8 + 2.9^2/8} \\\\Standard\ Deviation = \sqrt{{2.75} }\\\\Standard\ Deviation = 1.65\ minutes\)

So, the mean and standard deviation of the sampling distribution of the difference in sample means xF - xM are 1.5 and 1.65 minutes, respectively.

b. The probability of getting a difference in sample means xF - xM that is less than 0 can be found using a standard normal distribution table. First, we need to standardize the difference in sample means xF - xM by subtracting the mean and dividing by the standard deviation:

z = (xF - xM - (μF - μM)) / standard deviation

z = (0 - 1.5) / 1.65 = -0.91

Looking up -0.91 in a standard normal distribution table, we find that the probability of getting a difference in sample means xF - xM that is less than 0 is approximately 0.20.

So, there is a 20% probability of getting a difference in sample means xF - xM that is less than 0.

Hence, The mean and standard deviation of the sampling distribution of the difference in sample means xF - xM are 1.5 and 1.65 minutes and probability of getting a difference in sample means xF - xM that is less than 0 is approximately 0.20.

Step-by-step explanation:

Answer: a) 10

Step-by-step explanation:

Buscando en google, encuentro que la expresión es:

C(x) = 9*x^2 - 80*x - 100

Queremos encontrar el valor de x (positivo), tal que esa expresión sea igual a cero, entonces tenemos que resolver:

9*x^2 - 80*x - 100 = 0.

Para ello podemos recordar la ecuación de Bhaskara, que para una ecuación de la forma:

a*x^2 + b*x + c = 0

Las soluciones son:

\(x = \frac{-b +-\sqrt{b^2 - 4*a*c} }{2a}\)

en este caso, tenemos:

a = 9

b = -80

c = -100

Entoces, las soluciones van a ser:

\(x = \frac{-(-80) +- \sqrt{(-80)^2 - 4*9*(-100)} }{2*9} = \frac{80 +- 100}{18}\)

Entonces las dos soluciones son:

x = (80 - 100)/18 = -20/18 = -10/9

The bit-file necessary to program an FPGA to implement this function would depend on the specific FPGA and toolchain being used, but it would typically include a configuration bitstream that specifies the LUT programming values and the multiplexer configurations for each CLB in the design. The bitstream would also include the memory initialization values for the 8x2 memory.

CLBs (Configurable Logic Blocks) are a fundamental building block of FPGAs (Field-Programmable Gate Arrays). They typically consist of a configurable logic function implemented using LUTs (Look-Up Tables), along with a set of programmable multiplexers that can be used to connect inputs and outputs to the logic function.

To implement the function F(a,b,c,d) = ab + cd using CLBs with an 8x2 memory, we can use the following circuit:

           +------+

    a ---->|      |

           |  LUT |

    b ---->|      |---->+

           +------+     |

    c ---->|      |     |

           |  LUT |     |

    d ---->|      |-----+

           +------+

Here, each input (a,b,c,d) is connected to a separate LUT input, and the LUT is programmed to implement the desired function F. The output of the LUT is connected to a multiplexer, which can be used to select between the LUT output and an 8x2 memory output. The memory has 8 address lines and 2 data lines, which can be used to store two bits for each of the possible input combinations of a,b,c,d.

The function F(a,b,c,d) = ab + cd can be implemented using a 2-input LUT, an 8x2 memory, and a switching matrix in a configurable logic block (CLB) of an FPGA. The bit-file necessary to program the FPGA to implement this function would involve defining the input and output pins, initializing the LUT and memory with the required values, and configuring the switching matrix to connect the inputs and outputs appropriately.

A configurable logic block (CLB) is a basic building block of an FPGA that can be programmed to implement any digital logic function. Each CLB typically consists of a number of components, including a 2-input look-up table (LUT), a flip-flop, and a switching matrix that connects the various inputs and outputs. In order to implement the function F(a,b,c,d) = ab + cd using a CLB, we would need to use the LUT to compute the product terms ab and cd, and then use the memory to store the results.

The switching matrix would be used to connect the external inputs a, b, c, and d to the appropriate inputs of the LUT and memory, and to connect the outputs of the LUT and memory to the output pin of the CLB. The bit-file necessary to program the FPGA to implement this function would therefore involve defining the input and output pins, initializing the LUT and memory with the required values, and configuring the switching matrix to connect the inputs and outputs appropriately.

To initialize the LUT with the required values, we would need to program it with the truth table for the function F(a,b,c,d). Since this function has four inputs, there are 2^4 = 16 possible input combinations, and the corresponding output values can be computed using the formula F(a,b,c,d) = ab + cd. We would need to program the LUT with these 16 output values, so that it can compute the function for any input combination.

The 8x2 memory would be used to store the intermediate results ab and cd, which can then be combined using a second LUT to compute the final output of the function. The switching matrix would be used to connect the inputs a, b, c, and d to the appropriate inputs of the LUT and memory, and to connect the outputs of the LUT and memory to the output pin of the CLB. By configuring the switching matrix appropriately, we can ensure that the correct inputs are connected to the correct components, and that the final output of the function is sent to the correct output pin of the FPGA.

Answer:

Accoding to the calculations , the correct answer is:

A) Depreciation charge 16,000; revaluation surplus £20,000

According to IAS 16 Property, Plant and Equipment, the depreciation charge for an asset should be based on its carrying amount, useful life, and residual value.

In this case, the buildings were purchased for £400,000 (£480,000 - £80,000) and had a useful life of 25 years. Since there is no residual value, the depreciable amount is equal to the initial cost of the buildings (£400,000).

To calculate the annual depreciation charge, we divide the depreciable amount by the useful life:

£400,000 / 25 = £16,000

Therefore, the depreciation charge for the year ended 30 September 2021 is £16,000.

Now, let's calculate the balance on the revaluation surplus as at that date.

The revaluation surplus is the difference between the fair value of the property and its carrying amount. On 1 October 2020, the property was revalued to £500,000, and the carrying amount was £480,000 (£400,000 for buildings + £80,000 for land).

Revaluation surplus = Fair value - Carrying amount

Revaluation surplus = £500,000 - £480,000

Revaluation surplus = £20,000

Therefore, the balance on the revaluation surplus as at 30 September 2021 is £20,000.

Based on the calculations above, the correct answer is:

Answer:

Step-by-step explanation:

The population of an island in 1950 was 2 million. The population grew exponentially for 63 years and reached 6.5 million in 2013. The carrying capacity of the island is estimated to be 10 million.

If the population growth rate in the future is similar to the last 50 years, what will the population be in 2050

The population is given to be increasing exponentially, which means it will follow the equation:

\($P(t) = P_0 e^{rt}$\)Here,\($P(t)$\) is the population after a period of time \($t$, $P_0$\) is the initial population, $r$ is the annual growth rate (which we are given is the same as the growth rate of the last 50 years), and \($t$\) is the time.

We can find the annual growth rate $r$ using the formula:\($$r = \frac{\ln{\frac{P(t)}{P_0}}}{t}$$\)
We know\($P_0 = 2$ million, $P(t) = 6.5$ million, and $t = 63$\) years. Substituting these values, we get:

\($r = \frac{\ln{\frac{6.5}{2}}}{63} = 0.032$\) (rounded to 3 decimal places)

Since the carrying capacity of the island is 10 million, we know that the population will not exceed this limit.

Therefore, we can use the logistic model to find the population growth over time. The logistic growth model is:

\($$\frac{dP}{dt} = r P \left(1 - \frac{P}{K}\right)$$\)

where $K$ is the carrying capacity of the environment. This can be solved to give:\($P(t) = \frac{K}{1 + A e^{-rt}}$\)

where \($A = \frac{K-P_0}{P_0}$. We know $K = 10$ million, $P_0 = 2$ million, and $r = 0.032$\). Substituting these values, we get:\($A = \frac{10-2}{2} = 4$\)

Therefore, the equation for the population of the island is:\($P(t) = \frac{10}{1 + 4 e^{-0.032t}}$\)

To find the population in 2050, we substitute\($t = 100$\) (since 63 years have already passed and we want to find the population in 2050, which is 100 years after 1950):

\($P(100) = \frac{10}{1 + 4 e^{-0.032 \times 100}} \approx \boxed{8.76}$ million\)
Therefore, the estimated population of the island in 2050, assuming constant carrying capacity and consumption per capita, is approximately 8.76 million.

The volume of the triangular prism is 216 cubic meters.

To find the volume of a triangular prism, we need to multiply the area of the triangular base by the length of the prism.

Calculate the area of the triangular base.

The base of the triangular face is given as 8 meters, and the height is 9 meters. We can use the formula for the area of a triangle: area = (1/2) * base * height.

Plugging in the values, we get:

Area = (1/2) * 8 meters * 9 meters = 36 square meters.

Multiply the area of the base by the length of the prism.

The length of the prism is given as 12 meters.

Volume = area of base * length of prism = 36 square meters * 12 meters = 432 cubic meters.

Adjust for the shape of the prism.

Since the prism is a triangular prism, we need to divide the volume by 2.

Adjusted Volume = (1/2) * 432 cubic meters = 216 cubic meters.

Therefore, the volume of the triangular prism is 216 cubic meters.

The exponential function that goes through the points (0,7) and (2,112) is y = 7 × 4ˣ.

To write an exponential function that goes through the points (0,7) and (2,112), we can use the general form of an exponential function:

y = abˣ

where a is the initial value, b is the base, and x is the independent variable (usually time).

Using the two points given to find the values of a and b.

Let's start with the point (0, 7):

y = a × bˣ

Plug in x = 0 and y = 7

7 = a ×  b⁰

7 = a × 1

a = 7

Next, let's use the point (2, 112):

y = a × bˣ

Plug in x = 2, y = 112 and a = 7

112 = 7 × b²

7b² = 112

Dvide both sides by 7

b² = 16

b = ±√16

b = ±4

We can eliminate the negative solution since we are looking for a function that is growing, so:

b = 4

Now, plug these values into y = a × bˣ

y = 7 × 4ˣ

Therefore, the exponential function y = 7 × 4ˣ

The estimated probability that the candidate obtains a score greater than or equal to 10 is 0.7234, rounded to four decimal places, so the answer is (A).

The number of correct answers that the candidate gets is a binomial random variable with parameters n = 40 (number of trials) and p = 1/5 (probability of success). We want to find the probability that the candidate gets a score greater than or equal to 10, which is equivalent to getting 10 or more questions correct.

Using the normal approximation to the binomial distribution with continuity correction, we can approximate the distribution of the number of correct answers by a normal distribution with mean μ = np = 40 * 1/5 = 8 and variance σ^2 = np(1-p) = 40 * 1/5 * 4/5 = 6.4.

To find the probability that the candidate gets 10 or more questions correct, we can standardize the normal distribution and use the standard normal distribution table or R to find the probability.

Let X be the number of correct answers. Then, we have:

P(X >= 10) = P((X - μ) / σ >= (10 - μ) / σ)

= P(Z >= (10 - 8) / sqrt(6.4)), where Z is a standard normal random variable.

The probability that exactly 4 seeds don't grow out of 11 planted is approximately 0.992.

This is a binomial distribution problem, where the probability of success (plant growing) is p = 0.6 and the probability of failure (plant not growing) is q = 1 - p = 0.4. We want to find the probability that exactly 4 seeds don't grow out of 11 planted.

The formula for this is:

P(X = k) = (n choose k) * p^k * q^(n-k)

where X is the number of seeds that don't grow, k = 4, n = 11, (n choose k) is the binomial coefficient which can be calculated as (n choose k) = n! / (k!(n-k)!), and p and q are the probabilities of success and failure respectively.

Substituting the values, we get:

P(X = 4) = (11 choose 4) * 0.4^4 * 0.6^7

= (11! / (4! * 7!)) * 0.0256 * 0.1176

= 330 * 0.003008256

= 0.99227008
