Consider a series system consisting of n independent components. Assuming that the lifetime of the ith component is Weibull distributed with parameter X, and a, show that the system lifetime also has a Weibull distribution. As a concrete example, consider a liquid cooling cartridge system that is used in enterprise-class servers made by Sun Microsystems [KOSL 2001]. The series system consists of a blower, a water pump and a compressor. The following table gives the Weibull data for the three components. Component L10 (h) Shape parameter (a) Blower 70,000 3.0 Water pump 100,000 3.0 Compressor 100,000 3.0 L10 is the rating life of the component, which is the time at which 10 % of the components are expected to have failed or R(L10) = 0.9. Derive the system reliability expression.

Answer:

8.7

Step-by-step explanation:

Since a square has equal side lengths, the formula for area is s^2, where s stands for side. Since we are given the area, s^2=75 square feet. Take the square root of both sides to get s is equivalent to the square root of 75 square feet. When this becomes a decimal, it is 8.66 feet. Since we are supposed to round to the nearest tenths, it rounds up to 8.7 feet per side length

The reasonableness of assuming equal standard deviations depends on factors such as sample size, data distribution, and prior knowledge. It is important to assess these factors and make an informed decision based on the specific context and characteristics of the data being analyzed.

To determine whether it is reasonable to assume equal standard deviations when analyzing the data, we need to consider the nature of the data and the underlying assumptions of the statistical analysis method being used.

Assuming equal standard deviations means that we are assuming that the variability of the data is the same across all groups or populations being compared. This assumption is often made in statistical analyses such as analysis of variance (ANOVA) or t-tests when comparing means between groups.

Whether it is reasonable to assume equal standard deviations depends on the specific context and characteristics of the data. Here are a few factors to consider:

Sample size: If the sample sizes for each group or population being compared are similar, it may be more reasonable to assume equal standard deviations. Larger sample sizes provide more reliable estimates of the standard deviation and can help ensure that the assumption is met.

Similarity of data distribution: If the data in each group or population exhibit similar distributions and variability, assuming equal standard deviations may be reasonable. However, if the data distributions are visibly different or have varying levels of variability, assuming equal standard deviations may not be appropriate.

Prior knowledge or research: If there is prior knowledge or research suggesting that the standard deviations are likely to be equal across groups, it may be reasonable to make this assumption. However, if there is prior information indicating unequal standard deviations, it would be more appropriate to consider unequal standard deviations in the analysis.

Step-by-step explanation:

The present value of $5,000 received in two years with an interest rate of 7% is approximately $4,366.93.

To calculate the present value of $5,000 received in two years with an interest rate of 7%, we need to discount the future value to its present value using the formula:

Present Value = Future Value / (1 + Interest Rate)^n

Where:

Future Value = $5,000 (the amount to be received in two years)

Interest Rate = 7% (expressed as a decimal, 0.07)

n = 2 (number of years)

Substituting the given values into the formula, we have:

Present Value = $5,000 / (1 + 0.07)^2

Calculating the expression inside the parentheses:

(1 + 0.07)^2 = 1.07^2 = 1.1449

Dividing $5,000 by 1.1449:

Present Value ≈ $4,366.93

Therefore, the present value of $5,000 received in two years with an interest rate of 7% is approximately $4,366.93.

To accurately estimate ln 1.4 to within 0.0001., we need at least 7 terms.

What does Maclaurin series mean?

Given the values of the function's successive derivatives at zero, a Maclaurin series is a power series that enables one to construct an approximation of a function with input values close to zero.

The Maclaurin series is what?

A Taylor series centered on zero is referred to as a Maclaurin series.

Presented function is:

f(x)=ln(1+x)

We are aware of the following expansion of ln(1+x) near zero (up to 7 terms):

\(ln(1+x)=x-\frac{x^{2} }{2} +\frac{x^{2} }{3}-\frac{x^{2} }{4}+\frac{x^{2} }{5}-........\)
Where \(-1\leq x\leq 1\)
Put x=0.4 in the preceding series for ln 1.4.

\(ln(1+0.4)=x-\frac{0.4^{2} }{2} +\frac{0.4^{2} }{3}-\frac{0.4^{2} }{4}+\frac{0.4^{2} }{5}-........\)
\(ln(1.4)=0.3365333\)

Therefore, to estimate ln 1.4 to within 0.0001, we require at least 7 terms.

cos S = adjacent side / hypotenuse = 36/85

tan S = opposite side / adjacent side = 77/36.

Answer:

see explanation

Step-by-step explanation:

sin S = \(\frac{opposite}{hypotenuse}\) = \(\frac{TU}{TS}\) = \(\frac{77}{85}\)

cos S = \(\frac{adjacent}{hypotenuse}\) = \(\frac{SU}{TS}\) = \(\frac{36}{85}\)

tan S = \(\frac{opposite}{adjacent}\) = \(\frac{TU}{SU}\) = \(\frac{77}{36}\)

Answer:

15.4 lbs

Step-by-step explanation:

Since the average of the top five is 13.3 this says that:

total weight of all the fish / 5 = 13.3 lbs

Therefore, the total weight of all five fish is equal to:

13.3 * 5 = 66.5

With this number, I subtracted all the other weights and found that the missing weight was:

15.4lbs.

Therefore, Wayne S. had the biggest fish weighing 15.4lbs

Answer:

15.4

Step-by-step explanation:

(14.2 + 13.4 + 12.1 + 11.4 + X) / 5 = 13.3

(51.1 + X) / 5 = 13.3

Cross:

51.1 + X = 66.5

then X = 66.5 - 51.1

To find the value of the effective spring constant (k), we are given the masses of oxygen (16.0 atomic mass units) and carbon (12.0 atomic mass units). We will use this information to determine the value of k.

The effective spring constant (k) is a measure of the stiffness of the spring and is usually given in units of force per unit length or mass per unit time squared. In this case, we need to determine k based on the masses of oxygen and carbon.

To find k, we can use the formula for the effective spring constant in a molecular vibration system, which is given by:

K = (ω^2)(μ)

Where ω is the angular frequency of the vibration and μ is the reduced mass of the system.

Since we are given the masses of oxygen and carbon, we can calculate the reduced mass (μ) as follows:

Μ = (m1 * m2) / (m1 + m2)

Where m1 and m2 are the masses of oxygen and carbon, respectively.

Using the given masses:
M1 = 16.0 atomic mass units (oxygen)
M2 = 12.0 atomic mass units (carbon)

We can substitute these values into the equation for μ:

Μ = (16.0 * 12.0) / (16.0 + 12.0)
= 192.0 / 28.0
≈ 6.857 atomic mass units

Now, to find the value of k, we need the angular frequency (ω) of the vibration. Unfortunately, the angular frequency is not provided in the given information. Without the angular frequency, we cannot determine the exact value of k.

Therefore, we can calculate the reduced mass (μ) using the given masses of oxygen and carbon, but we cannot find the value of k without the angular frequency.

Answer:

Probability that the two socks picked by Natalie are of the same colours = (17/32) = 0.53125

Step-by-step explanation:

Complete Question

Natalie has 8 socks in a drawer.

5 of the socks are black.

3 of the socks are white.

Natalie takes out a sock at random, writes down its colour and puts it back into

the drawer. Then Natalie takes out a second sock, at random, and writes down its colour.

Work out the probability that the two socks are of the same colour.​

Solution

This is a probability that involves replacement.

Probability of an event is given as the number of elements in the event divided by the total number of elements in the sample space.

If the event that a black socks is picked = P(B)

Then, the event that a white socks is picked = P(W)

P(B) = n(B) ÷ n(S)

n(B) = 5

n(S) = 8

P(B) = (5/8)

P(W) = n(W) ÷ n(S) = (3/8)

Probability that the two socks picked by Natalie are of the same colours = (Probability that the two socks picked are black) + (Probability that the two socks picked by Natalie are white)

Probability that the two socks picked are black = (5/8) × (5/8) (since the socks are picked and replaced, the probability stays the same)

= (25/64)

Probability that the two socks picked by Natalie are white = (3/8) × (3/8) = (9/64)

Probability that the two socks picked by Natalie are of the same colours

= (25/64) + (9/64)

= (34/64)

= (17/32) = 0.53125
