The probability that one or more machine failures occur in a given day, given that the company experienced ten failures in the past 100 days, is option c) 0.095.

To calculate the probability of one or more machine failures occurring in a given day, we can use the concept of the complement rule. The complement rule states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring.

Given that the company experienced ten failures in the past 100 days, we can calculate the probability of no failures occurring in a day by dividing the number of failure-free days by the total number of days:

No. of failure-free days = Total days - No. of failures = 100 - 10 = 90

Now, the probability of no failures in a day is calculated by dividing the number of failure-free days by the total number of days:

Probability of no failures = No. of failure-free days / Total days = 90 / 100 = 0.9

Finally, to find the probability of one or more failures occurring in a day, we use the complement rule:

Probability of one or more failures = 1 - Probability of no failures = 1 - 0.9 = 0.1

Therefore, the probability that one or more machine failures occur in a given day is 0.1, which corresponds to option c).

The connection string for SQL Server using Windows Authentication is as follows:

Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;

Specify the server address in the format "Server=myServerAddress". Replace "myServerAddress" with the name or IP address of the SQL Server instance you want to connect to.

Specify the name of the database you want to connect to in the format "Database=myDataBase". Replace "myDataBase" with the name of the database.

Use Windows Authentication by setting "Trusted_Connection=True". This means that the user running the application is authenticated using their Windows credentials, rather than a SQL Server login.

Use semicolons (;) to separate the different parts of the connection string.

Using Windows Authentication is a more secure and convenient way to connect to a SQL Server database, as it eliminates the need to store and manage login credentials in the application.

There are a total of 2,598,960 ways to deal 5 cards to each of the five players in a game of poker.

To calculate the number of ways to deal the cards, we can use the concept of combinations. In this case, we need to determine the number of combinations of 5 cards from a deck of 52 cards.

The number of combinations can be calculated using the formula C(n, r) = n! / (r! * (n - r)!), where n is the total number of items and r is the number of items to be chosen.

In this scenario, there are 52 cards in the deck, and each player is dealt 5 cards. So, we need to calculate C(52, 5) for each player. Since there are five players, we multiply the result by 5.

Therefore, the total number of ways to deal 5 cards to each of the five players is C(52, 5) = (52! / (5! * (52 - 5)!)) = 2,598,960.Hence, there are 2,598,960 ways to deal the cards in a game of poker when each of the five players is dealt 5 cards from a 52-card deck.

ANSWER:

356°

STEP-BY-STEP EXPLANATION:

Coterminal angles are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side. For example 30°, –330° and 390° are all coterminal.

In this case we have the angle -4° and its coterminal angle will be:

Coterminal angle in [0, 360°) range is 356°, located in the fourth quadrant

Therefore, the correct answer is 356°

When the population standard deviation is unknown and the sample size is less than 30, we need to use the t-distribution to compute a confidence interval for the mean, and we should consult a t-table to find the appropriate t-value based on the degrees of freedom and the desired level of confidence.

When the population standard deviation is unknown and the sample size is less than 30, we need to use the t-distribution to compute a confidence interval for the mean.

The t-distribution is similar to the standard normal distribution, but with heavier tails, and it is used when the population standard deviation is unknown.

To compute the confidence interval for the mean using the t-distribution, we need to find the appropriate t-value from a t-table. The t-table provides critical values for different degrees of freedom and levels of confidence.

The degrees of freedom for a t-distribution with a sample size of n is (n-1). For example, if we have a sample size of 20, the degrees of freedom would be 19.

To find the appropriate t-value from the t-table, we need to know the degrees of freedom and the desired level of confidence. For example, if we have a sample size of 20 and want to calculate a 95% confidence interval, we would look for the t-value with 19 degrees of freedom and 0.025 (0.05/2) in the middle of the table. This t-value would be used in the formula to calculate the confidence interval for the mean.

Did you learn about equal rectangles? we can prove AEB and CED are equal, which results in what we need to prove here

AE = CE and BE = DE. This can be proved with the help of the properties of congruent triangles.

'A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.'

According to the given problem,

ABCD is a parallelogram.

We know,

BC ║ AD and BC ≅ AD

From, the properties of a parallelogram,

∠CBD = ∠ADB

∠BCA = ∠DAC

We know, two lines are parallel and alternate interior angles of the parallelogram are equal.

Also, Δ BEC ≅ ΔAED (Angle-Side-Angle)

Therefore, AE ≅ CE ( The properties of congruent triangles )

                  BE ≅ DE ( The properties of congruent triangles )

Hence, we can conclude, in the parallelogram ABCD, AE = CE and BE = DE from the properties of congruent triangles.

The standars deviation (s) in this set of samples is: s = 1.62

In this question we have been given set of the weights in grams of the mice after three weeks on the diet recorede by Dr. Ambrose while conducting a study on the growth rates of mice on a copper deficient diet.

We need to find the the standard deviation (s) in this set of samples.

First we find the mean,

μ = (12 + 11.3 + 15.9 + 12.5 + 12)/5

μ = 12.74

We know that the formula for standard deviation,

s = √[∑(x - μ)²/N]

First we find ∑(x - μ)²

= (12 - 12.74)² + (11.3 - 12.74)² + (15.9 - 12.74)² + (12.5 - 12.74)² + (12 - 12.74)²

= 13.21

So, the standard deviation,

s = √(13.21 / 5)

s = 1.62

Therefore, the standard deviation is 1.62

The number of comparisons that the algorithm must perform is 10.

To get the solution, we need to analyze the given algorithm.

Consider the following algorithm to sort three integers x, y, and z in non-decreasing order using only two comparisons: if x > y, then swap (x, y);

if y > z, then swap (y, z);

if x > y, then swap (x, y);

For a given set of values of x, y, and z, the algorithm makes a maximum of two swaps.

Hence, for 10 given input values, the algorithm would perform a maximum of 20 swaps.

The length of the diagonal should be 17 ft.

To find the length of the diagonal, we can use the Pythagorean theorem, which states that the square of the length of the diagonal of a right triangle is equal to the sum of the squares of the lengths of the other two sides.

Let's call the length of one wall 8 ft and the length of the other wall 15 ft. If the corner of the room is square, then the diagonal forms the hypotenuse of a right triangle.

So, using the Pythagorean theorem:

diagonal^2 = 8^2 + 15^2

diagonal^2 = 64 + 225

diagonal^2 = 289

Taking the square root of both sides:

diagonal = √289

diagonal = 17 feet
