A mean of a normal distribution's upper bound of a 95% confidence interval is 58.11.

For the given question,

The confidence bound's upper limit (UCB) is determined as follows:

UCB =  μ + z(α/2)×σ/√n

Now, α/2 = (1 - 0.95)/2

α/2 = 0.025

z(α/2) = 1.96  (obtain from t-distribution table for degree of freedom)

Put the values in the formula,

UCB =  μ + z(α/2)×σ/√n

UCB = 36.96 + 1.96×41.8/√15

UCB = 58.11

As a result, 58.11 is the upper bound of a 95% confidence interval for the mean of a normal distribution.

If h(x) = 6 5f(x) , where f(5) = 6 and f '(5) = 4, then h'(5). h'(5) =20

To find h'(5) given h(x) = 6 + 5f(x), f(5) = 6, and f'(5) = 4, follow these steps:

1. Differentiate h(x) with respect to x: h'(x) = 0 + 5f'(x) (since the derivative of a constant is 0, and we use the chain rule for the second term).

2. Now, h'(x) = 5f'(x).

3. Plug in the given values: h'(5) = 5f'(5).

4. Since f'(5) = 4, substitute this value: h'(5) = 5 * 4.

5. Compute the result: h'(5) = 20.

So, h'(5) = 20.

The solution for this system of equations. 12x+ 15y = 34 -6x+ 5y = 3

is (x,y) =(2/3, 8/5)

Given a system of equations,

12x + 15y = 34  ------(1)

-6x + 5y = 3 ------(2),

To solve this we use the elimination method

In the elimination method, you either add or subtract the equations to get an equation in one variable.

Equation (1) + 2 × Equation (2),

We get,

(12x+15y=34)+(-12x+10y=6)

⇒ 15y+10y=34+6

⇒ 25y=40

⇒ y=40/25

⇒ y=8/5

From equation (2),

⇒  -6x+5(y)=6

⇒  -6x+5(8/5)=6

⇒  -6x+8=6

⇒  -6x=-2

⇒ x=2/3

Hence the solution for this system of equations. 12x 15y = 34 -6x 5y = 3

is (x,y =(2/3, 8/5)

The fundamental period of the discrete-time signal x[n] is 10 samples.

N * 0.1 = 1

N = 1 / 0.1

N = 10

The given analog signal is x(t) = 1 + cos(2πt + 4π).

The fundamental frequency (f) of a periodic signal is the inverse of the fundamental period (T), and it represents the frequency at which the signal repeats.

In the given signal x(t), the coefficient of t in the argument of the cosine function is 2π, which corresponds to a frequency of 1 cycle per unit time (1 Hz). Therefore, the fundamental frequency of x(t) is 1 Hz.

The fundamental period (T) is the time it takes for the signal to complete one full cycle. In this case, the argument of the cosine function in x(t) is 2πt + 4π, which completes one full cycle when it increases by 2π. So, the fundamental period of x(t) is 1/1 = 1 second.

To determine the fundamental period of the discrete-time signal x[n], obtained by sampling x(t) with a sampling period T = 0.1 seconds, we need to find the smallest positive integer N for which N * T is equal to the fundamental period of x(t).

Since the fundamental period of x(t) is 1 second, we can calculate:

N * 0.1 = 1

N = 1 / 0.1

N = 10

To find the fraction of guests that ordered chicken, we must evaluate:

Fixed overheads are allocated to products on the number of litres of ice cream produced, irrespective of the size of the output. Liters Rands Expected Sales :500 ml ice cream = 60,000 litres

= 60,000 x R10

= R 600,0001 litre

ice cream = 80,000

litres = 80,000 x R 15 = R1,200,000

Total expected sales volume 140,000 litres R1,800,000 . From the given question, we are told that inventory is valued on the basis of equivalent units of inventory. Which means that two 500ml of ice cream is valued the same as one litre of ice cream. We are also told that variable overheads vary with direct labour hours. Fixed overheads are allocated to products on the number of litres of ice cream produced, irrespective of the size of the output.

Using this information we can prepare a sales budget for the company by estimating the sales volume in litres for each of the two sizes of ice cream containers and multiplying the sales volume by the respective sale price of each size. Since the number of litres is used to allocate fixed overheads, it is necessary to prepare the budget in litres as well. The total expected sales volume can be calculated by adding up the expected sales volume of the two sizes of ice cream products. The expected sales volume of 500 ml ice cream is 60,000 litres (500 ml x 0.12 million) and the expected sales volume of 1 litre ice cream is 80,000 litres (1 litre x 0.08 million). Adding up the two volumes, we get a total expected sales volume of 140,000 litres.

The probability of the sample mean weight being greater than 3.55 kg is 0.1230, rounded to 4 decimal places.

We can solve this problem by using the Central Limit Theorem (CLT). The CLT states that the sample means of a sufficiently large sample size from any population will be normally distributed, regardless of the population's underlying distribution.

In this case, we know the population mean (μ = 3.4 kg) and the population standard deviation (σ = 0.5 kg). We also know the sample size (n = 15) and the desired probability of the sample mean being greater than 3.55 kg.

To apply the CLT, we need to calculate the sample mean (x') and the standard error (SE) of the sample mean. The sample mean can be calculated by adding up the weights of the 15 full-term female babies and dividing by 15.

x' = (sum of weights)/n = (15*3.4) / 15 = 3.4 kg

The standard error of the sample mean can be calculated by dividing the population standard deviation by the square root of the sample size.

SE = σ/√n = 0.5/√15 = 0.1291 kg

Next, we need to standardize the sample mean using the standard normal distribution (z-distribution).

z = (x' - μ) / SE = (3.55 - 3.4) / 0.1291 = 1.16

Using a standard normal table or calculator, we find that the probability of getting a z-score greater than 1.16 is 0.1230.

In conclusion, the probability of obtaining a sample mean weight greater than 3.55 kg from a sample of 15 full-term female babies is approximately 0.1230.

This means that there is a 12.30% chance of obtaining a sample mean weight greater than 3.55 kg if we randomly select 15 full-term female babies from the population with mean 3.4 kg and standard deviation 0.5 kg.

The answer is postulate. That is a rule that is accepted as true without proof.

To simplify the expression 2y + 3x + 4, we can start by grouping the like terms, which are the terms with the same variable(s) raised to the same power.

In this case, the terms 2y and 3x have different variables, so we cannot combine them directly. Therefore, we can rewrite the expression as:

2y + 3x + 4

Since there are no like terms to combine, we have simplified the expression as much as possible. Thus, the final simplified form of the expression 2y + 3x + 4 is simply 2y + 3x + 4.
