Step-by-step explanation:

It will take approximately 737.33 minutes for the amount of water in the bathtub to reach 2212 gallons.

To find the number of minutes it will take for the amount of water in the bathtub to reach 2212 gallons, we can set up a proportion. Let's denote the number of minutes as t. We know that the rate of drainage is 3 gallons per minute, so the amount of water drained in t minutes is 3t gallons. The initial amount of water in the bathtub is 45 gallons, and we want to find the time it takes for the total amount of water to be 2212 gallons.

Using the proportion:(3t) / 45 = 2212 / 45. Cross-multiplying, we get: 3t = 2212. Dividing both sides by 3, we have: t = 2212 / 3. Calculating this value, we find: t ≈ 737.33. Therefore, it will take approximately 737.33 minutes for the amount of water in the bathtub to reach 2212 gallons.

In multiple regression, we have 4 assumptions listed and explained below. They are valid.

Following are assumptions for multiple regression model:

1. Linear connection: Each predictor variable and the responder variable have a linear relationship.

Making a scatter plot of each predictor variable and the response variable is the simplest technique to check if this premise is true.

2. Lack of Multicollinearity: There is no significant correlation between any of the predictor variables.

Calculating the VIF value for each predictor variable is the quickest approach to see if this premise is true.

3. Independence: Each observation has its own validity.

The Durbin-Watson test, a formal statistical test that informs us whether or not the residuals (and consequently the observations) exhibit autocorrelation, is the easiest approach to find out if this assumption is true.

4. Homoscedasticity: At every point in the linear model, the residuals' variance is constant.

The simplest technique to check if this premise is true is to plot the standardized residuals against the expected values.

The answer is 0.01201778632

Step-by-step explanation:

The probability that you have more than 210 bugs total on the 30 pages is 1 or 100%.

An even distribution of 5 to 7+y defects can be found on a single page of code, where y is an unidentified parameter. By using the information that the average number of defects per page is (5 + (7+y))/2 = 6 + y/2, we can determine y. Given that the overall number of bugs should divide by the number of pages (30), the mean number of bugs per page should be equal to: 30 / total amount of bugs = 6 + y/2

By calculating y, we obtain:

y = (5 - total amount of bugs - 60)

Because of this, the distribution of all 30 pages' worth of bugs is also uniformly distributed, with a lowest value of 530 = 150 and a highest value of 730 = 210.

We must determine the percentage of the overall distribution that is above 210 in order to calculate the likelihood that there are more bugs than 210 in total. The percentage of the range that is above 210, which is just because the distribution is uniform, is as follows: (210 - 150) / (730 - 530) = 60 / 60 = 1

Therefore, the probability that there are more than 210 defects overall is 1, or 100%.

The correct option is A. Yes, λ=4 is an eigenvalue of the matrix.

To find the corresponding eigenvector, we need to solve the equation (A - λI)x = 0, where A is the given matrix, λ is the eigenvalue, I is the identity matrix, and x is the eigenvector.
First, we subtract λI from A:
A - λI = 3-4 -4 0 0 3-4 3 2-4 -2 6
= -1 -4 0 0 -1 3 2 -2 2
Next, we set the equation (A - λI)x = 0 and solve for x:
(-1 -4 0) (x1) = 0
(0 -1 3) (x2) = 0
(2 -2 2) (x3) = 0
Simplifying the equations gives us:
-x1 - 4x2 = 0
-x2 + 3x3 = 0
2x1 - 2x2 + 2x3 = 0
We can solve this system of equations to find the eigenvector. One possible solution is x1 = 2, x2 = 1, x3 = 1/3. Therefore, one corresponding eigenvector is (2, 1, 1/3).
So the correct answer is A. Yes, λ=4 is an eigenvalue of the matrix. One corresponding eigenvector is (2, 1, 1/3).

Using the binomial distribution, it is found that there is a 0.0108 = 1.08% probability of the coin landing tails up at least nine times.

The formula is:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

In this problem:

The probability that is lands tails up at least nine times is given by:

\(P(X \geq 9) = P(X = 9) + P(X = 10)\)

In which:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 9) = C_{10,9}.(0.5)^{9}.(0.5)^{1} = 0.0098\)

\(P(X = 10) = C_{10,10}.(0.5)^{10}.(0.5)^{0} = 0.001\)

Hence:

\(P(X \geq 9) = P(X = 9) + P(X = 10) = 0.0098 + 0.001 = 0.0108\)

0.0108 = 1.08% probability of the coin landing tails up at least nine times.

A LOD score is the ratio of probabilities that two genes are linked to the probability that they are not linked, expressed as a log10. This measure is commonly used in linkage analysis, a statistical method used to determine whether genes are located on the same chromosome and thus tend to be inherited together.

In linkage analysis, the LOD score is used to determine the likelihood that two genes are linked, based on the observation of familial inheritance patterns. A LOD score of 3 or higher is generally considered to be strong evidence for linkage, indicating that the likelihood of observing the observed inheritance pattern by chance is less than 1 in 1000.

The LOD score is also used to estimate the distance between two linked genes, with higher LOD scores indicating that the two genes are closer together on the chromosome. In general, the LOD score is a useful tool for identifying genetic loci that contribute to complex diseases or traits.

Answer:

Step-by-step explanation:

A type of graph that does not show the number of times a response was given is a qualitative or categorical graph. These graphs are used to represent categorical data where the focus is on the distribution or proportions of different categories rather than the frequency or count of each category.

Common types of qualitative graphs include:

Bar Graph: A bar graph represents categorical data using rectangular bars of different heights. Each bar corresponds to a specific category, and the height of the bar represents a certain characteristic or value associated with that category. The length of the bar is not proportional to the frequency of responses.

Pie Chart: A pie chart is a circular graph divided into slices, where each slice represents a category. The size of each slice corresponds to the proportion or percentage of responses in that category, but it does not show the actual count or frequency.

Radar Chart: A radar chart, also known as a spider chart or web chart, displays multivariate data on multiple quantitative variables. It uses a polygon with different arms or axes radiating from a central point, and each arm represents a different category or variable. The length or position along each arm indicates the magnitude or value of that variable, but it does not convey the frequency of responses.

In summary, qualitative or categorical graphs focus on representing categories and their proportions or distributions, rather than the number of times a response was given.

Answer:

Step-by-step explanation:

a. (I) x = 65

(ii) vertically opposite angles are equal.

b. (i) 71 degrees

(ii) alternate interior angles are equal

c. (i) z = 180 - 71 = 109 degrees

(ii) angles on a line add up to 180 degrees

Answer:

x = 65°, y = 71°, z = 44°

Step-by-step explanation:

x and 65 are vertical angles and congruent, thus

x = 65°

y and 71 are alternate angles and congruent, thus

y = 71°

The sum of the 3 angles in a triangle = 180°, thus

z = 180° - (65 + 71)° = 180° - 136° = 44°

The value of the rate of growth in Japan is - 0.55.

From the question above, :Birth rate = 7.7 per thousand

Death rate = 9.8 per thousand

Net migration = 0.55 per thousand

The rate of growth can be calculated using the following formula:

r = (birth rate - death rate) + net migration

Where,r = rate of growth

birth rate = number of live births per thousand in a population in a given year

death rate = number of deaths per thousand in a population in a given year

net migration = the difference between the number of people moving into a country (immigrants) and the number of people leaving a country (emigrants) per thousand in a given year

Putting the values in the formula we get,r = (7.7 - 9.8) + 0.55r = - 1.1 + 0.55r = - 0.55.

Therefore, the rate of growth in Japan is - 0.55.

If \(MU_{x}/P_{x}\)=30 and \(MU_{y} /P_{y}\)=40 then the consumer should buy the commodity y to maximise utility.

Given that \(MU_{x}/P_{x}\)=30 and \(MU_{y} /P_{y}\)=40 of commodities x and y.

Marginal utility is the additional utility that a consumer gets from consuming additional units of commodity. For maximising the utility of the consumer,the ratio of marginal utilities must be equal to the ratio of the products.

There can be two situations in our case:

Because \(MU_{x}/P_{x}\)<\(MU_{y} /P_{y}\)

So to equalise the ratio we need to reduce \(MU_{y} /P_{y}\). To reduce the utility of y the consumer needs to increase the consumption of y because as the consumption of commodity y increase it decreases the utility of commodity y.

Hence if \(MU_{x}/P_{x}\)=30 and \(MU_{y} /P_{y}\)=40 then the consumer should buy the commodity y to maximise utility.
