Statistical data of breakdowns of computer XXX show that the duration for trouble-free operation of the machine can be described as a gamma distribution with a mean of 40 days and a standard deviation of 10 days. The computer is occasionally taken out for maintenance in order to insure operational condition at any time with a 95% probability.
1. How often should the computer be scheduled for maintenance? Should it be shorter or longer than the mean of 40 days?
2. Three XXX computers were acquired at the same time by an engineering consulting firm. The computers are operating under the same environment, workload, and regular maintenance schedule. The breakdown times between the computers, however, may be assumed to be statistically independent. What is the probability that at least one of the three machines will break down within the first scheduled maintenance time?
1. In this case, we want the reliability to be 95%, so the probability of not breaking down is 0.95.
2. Probability of no breakdowns = (reliability of a single machine)^3. Probability of at least one breakdown = 1 - Probability of no breakdowns
1. To determine how often the computer should be scheduled for maintenance, we need to consider the reliability and the desired level of operational condition. Since the duration for trouble-free operation follows a gamma distribution with a mean of 40 days, this means that, on average, the computer can operate for 40 days before a breakdown occurs.
To ensure operational condition with a 95% probability, we can calculate the maintenance interval using the concept of reliability. The reliability represents the probability that the machine will not break down within a certain time period. In this case, we want the reliability to be 95%, so the probability of not breaking down is 0.95.
Using the gamma distribution parameters, we can find the corresponding reliability for a specific time duration. By setting the reliability equation equal to 0.95 and solving for time, we can find the maintenance interval:
reliability = 0.95
time = maintenance interval
Using reliability and the gamma distribution parameters, we can calculate the maintenance interval.
2. To calculate the probability that at least one of the three machines will break down within the first scheduled maintenance time, we can use the complementary probability approach.
The probability that none of the machines will break down within the first scheduled maintenance time is given by the reliability of a single machine raised to the power of the number of machines:
Probability of no breakdowns = (reliability of a single machine)^3
Since the breakdown times between the machines are statistically independent, we can assume that the reliability of each machine is the same. Therefore, we can use the reliability calculated in the first part and substitute it into the formula:
Probability of at least one breakdown = 1 - Probability of no breakdowns
By calculating this expression, we can determine the probability that at least one of the three machines will break down within the first scheduled maintenance time.

What is parallel lines?Parallel lines are two or more lines in a plane that never intersect, no matter how far they are extended in either direction. In other words, parallel lines are lines that are always the same distance apart and never touch or cross each other. In geometry, parallel lines are denoted by a double vertical bar symbol "||" placed between the two lines. For example, the lines AB and CD are parallel if and only if AB || CD. They form supplementary angles with a transversal that intersects them. Parallel lines are used in a variety of mathematical applications, such as in the study of Euclidean geometry, trigonometry, and calculus. They are also used in everyday situations, such as in road markings, train tracks, and architecture.
Here,
We are given that AD is parallel to BC and AB is parallel to CD. We need to prove that segment AB is congruent to segment CD.
Proof:
By the given information, AD is parallel to BC and AB is parallel to CD.
Since AD is parallel to BC and AB is parallel to CD, we have opposite angles congruent by the Alternate Interior Angles Theorem.
Let ∠A and ∠C be opposite angles, and let ∠B and ∠D be opposite angles.
We have ∠A ≅ ∠C and ∠B ≅ ∠D by the Alternate Interior Angles Theorem.
Therefore, triangles ABC and CDA are similar by the Angle-Angle (AA) Similarity Theorem.
By the definition of similarity, corresponding sides of similar triangles are proportional.
Since AB is a side of triangle ABC and CD is a corresponding side of triangle CDA, we have AB/CD = BC/DA.
Since AD is parallel to BC and AB is parallel to CD, we have BC/DA = AB/CD by the Alternate Interior Angles Theorem.
Combining equations (7) and (8), we have AB/CD = AB/CD.
Therefore, AB is congruent to CD by the Reflexive Property of Equality.

2 kg less than Alfie. What is the difference, in kilograms, between Tom and Alfie?
The difference between Tom and Alfie is 1 kg
Let's call the weight of Tom T, the weight of Harry H, the weight of Freddie F, and the weight of Alfie A. We are given that T = H + 5, H = F + 3, and F = A - 2.
Substituting the second and third equations into the first equation gives us:
T = (A - 2) + 3 + 5
T = A - 2 + 3 + 5
T = A + 1
So the difference between Tom and Alfie is T - A = A + 1 - A = 1 kg.

Answer:
Step-by-step explanation:
Hello!
*Full text*
A fisheries biologist has been studying horseshoe crabs. She has sampled 100 horseshoe crabs and recorded their weight (in kilograms) and width (in centimeters). The proposed regression equation is
weight = b + width * m
This model was fit to the data using the method of the least squares. The following results were obtained from statistical software.
(See attachment for output)
R2 = 0.423
A.) What is the regression equation for this example?
The estimate for the y-intercepts is b= 2.3013 and the estimate for the slope is m= 0.7963
In general, we can symbolize the estimated regression equation as ^Y= b + m*Xi. For this example you have to replace it with the calculated values of the regression coefficients to obtain the estimated regression equation:
^Y= 2.3013 + 0.7963Xi
B.) What is the explanatory, or predictor, variable in this study?
The explanatory or predictor variable is the variable that is suspected to have an effect over the response variable. In this example the predictor variable is:
X: Width of a horseshoe crab (cm)
C.) If the researcher wanted to test whether there is a statistically significant relationship between these two variables, what would the test statistic be? Calculate it from the table above.
To test if the regression is significant, the parameter of study will be the slope of the regression equation, symbolically: β. If the slope is equal to zero "β=0" then there is no linear regression between the response and explanatory variable. If the slope is different from zero "β≠0" then the regression is significant and the explanatory variable affects the response variable.
The hypotheses are:
H₀: β=0
H₁: β≠0
α: 0.05
\(t= \frac{m-\beta }{S_m} ~t_{n-2}\)
\(t_{H_0}= \frac{0.7963-0}{0.0939}= 8.48\)
The value of the statistic under the null hypothesis is t= 8.48
D.) What can we say about the p-value?
This test is two-tailed and so is the p-value, remember that the p-value is the probabulity of obtaining a value as extreme as the value of the statistic under the null hypothesis. The distribution for this test is a t with n-2= 100-2= 98 degrees of freedom. You can calculate the p-value as:
P(t₉₈≤-8.48) + P(t₉₈≥8.48)= P(t₉₈ ≤ -8.48) + (1 - P(t₉₈ < 8.48) ≅ 0.00001
E.) Ultimately, the reason that we find test statistics is so that we can compare them to a null distribution. For regression, that is a t-distribution based on the degrees of freedom. With 98 degrees of freedom (100-2), we can safely say that the critical t (or the confidence multiplier) is what?
As mentioned before, this test is two tailed, meaning that the rejection region is divided in two:
Critical values ±\(t_{n-2;1-\alpha /2}\) = ± \(t_{98; 0.975}\) = ± 1.984
This means that you'll reject the null hypothesis when the statistic is t ≤ -1.984 or if the statistic is t ≥ 1.984-
F.) Find the confidence interval for the slope.
Using a 95% confidence level, the interval for the slope is:
[m ± \(t_{n-2;1-\alpha /2}\) Sm]
[0.7963 ± 1.984 * 0.0939]
[0.61; 0.98]
G.) Is there a statistically significant relationship? Answer with the test statistic and the confidence interval.
Yes, there is a significant relationship between the width and weight of the horseshoe crabs.
Using the critical value approach:
The calculated statistic is 8.48 and the critical value is ± 1.984, since the statistic is greater than the positive critical value, the decision is to reject the null hypothesis.
If you pay attention to the confidence interval, which was made at a confidence level complementary to the significance level of the hypothesis test, this interval [0.61; 0.98] doesn't include the "zero". Since the interval doesn't include the value of the parameter stated in the null hypothesis, you can conclude that this hypothesis is not true and therefore reject it.
I hope this helps!

If p =(-4,6), find the image of p under the following rotation. 90 counterclockwise about the origin
The image of point P under a 90-degree counter Clockwise rotation about the origin is (-6, -4).
To find the image of point P = (-4, 6) after a 90-degree counterclockwise rotation about the origin, we can use the following formula:
(x', y') = (xcosθ - ysinθ, xsinθ + ycosθ)
where (x, y) are the coordinates of the original point, θ is the angle of rotation, and (x', y') are the coordinates of the rotated point.
In this case, θ = 90 degrees, so we have:
(x', y') = (-4cos90 - 6sin90, -4sin90 + 6cos90)
= (-6, -4)
Therefore, the image of point P under a 90-degree counterclockwise rotation about the origin is (-6, -4).

From the graph of the function, it's behavior on the intervals is given as follows:
Increasing: x >0.Decreasing: x < 0.When a function is increasing?Looking at the graph, we get that a function f(x) is increasing when it is "moving northeast" along the xy-plane, that is, to the right and up on the graph, meaning that when x increases, y increases.
Hence, from the graph of the function, it is increasing for the values to the right of x = 0, that is, on the interval x > 0.
When a function is decreasing?Looking at the graph, we get that a function f(x) is decreasing when it is "moving southeast" along the xy-plane, that is, to the right and down on the graph, meaning that when x increases, y decreases.
Hence, from the graph of the function, it is decreasing for the values to the left of x = 0, that is, on the interval x < 0.
