See attached. I know (very haphazard). But the basic method is to inverse the trig function. This gives you the position of the terminal angle. -45 degrees means that you turned 45 degrees clockwise and are in quadrant 4. This corresponds to an angle of rotation of 315 degrees counter clockwise which is what we are looking for since the specified domain is betwern 0 and 360 degrees or 0 and 2 pi.

The next thing to remember is that Tan is also negative in Quadrant 2 (using the ASTC rule). This corresponds to an angle of rotation of 180 - 45 = 135 degrees.

Hope that helps.

The statement "the expected value of an unbiased estimator is equal to the parameter whose value is being estimated" is true.

An estimator is a function of the sample data used to estimate the value of a population parameter. An estimator is said to be unbiased if its expected value is equal to the true value of the population parameter. In other words, if we were to repeatedly take samples from the population and calculate the estimator for each sample, the average value of the estimator over all the samples would be equal to the true value of the population parameter. The expected value of an unbiased estimator is a key property because it ensures that the estimator is not systematically overestimating or underestimating the population parameter. Instead, the estimator provides an unbiased estimate of the population parameter on average across all possible samples. It is important to note that not all estimators are unbiased. Biased estimators may systematically overestimate or underestimate the population parameter, leading to incorrect conclusions. Therefore, unbiasedness is a desirable property for an estimator to have.

The inverse of the conditional statement "If p then q" is, "p and not q".

What is conditional statement?

"If...then" is how a conditional statement is expressed. If we consider p and q to be the two statements, then p and q can be written under several conditions, such as;

If the "If" component (p) and the "then" part (q) of a conditional statement are both negated, this is known as a conditional statement in reverse. The conditional statement in geometry is known as p → q. Where stands for NOT or negating the statement, the inverse is written as  ~ p → ~  q.

In logic, "p and not q" is identical to the negation of "if p then q."

To find the total project completion time, we need to add the time required for each activity. Since the activities must be carried out sequentially, the total project completion time will be the sum of the times required for each activity.

The time required for activity a is uniformly distributed in the interval [1,5], so we can assume that the average time required for activity a is (1+5)/2 = 3.

The time required for activity b is uniformly distributed in the interval [2,3], so we can assume that the average time required for activity b is (2+3)/2 = 2.5.

The time required for activity c is uniformly distributed in the interval [3,6], so we can assume that the average time required for activity c is (3+6)/2 = 4.5.

Therefore, the total project completion time is:

Total project completion time = time for activity a + time for activity b + time for activity c
= 3 + 2.5 + 4.5
= 10

To run 1000 simulation trials in Excel, we can use the RAND function to generate random numbers between 0 and 1. We can then multiply these random numbers by the range of each activity to get a simulated completion time for each activity. We can then add up the simulated completion times for each trial to get a simulated total project completion time.

Here are the steps to run 1000 simulation trials in Excel:

1. In cell A1, enter "Trial" as the column header.

2. In cell B1, enter "Time for Activity A" as the column header.

3. In cell C1, enter "Time for Activity B" as the column header.

4. In cell D1, enter "Time for Activity C" as the column header.

5. In cell E1, enter "Total Project Completion Time" as the column header.

6. In cell A2, enter "1" as the first trial number.

7. In cell B2, enter the formula "=RAND()*(5-1)+1" to generate a random number between 1 and 5 for activity a.

8. In cell C2, enter the formula "=RAND()*(3-2)+2" to generate a random number between 2 and 3 for activity b.

9. In cell D2, enter the formula "=RAND()*(6-3)+3" to generate a random number between 3 and 6 for activity c.

10. In cell E2, enter the formula "=B2+C2+D2" to calculate the total project completion time for trial 1.

11. Select cells B2:E2 and drag the fill handle down to fill in the formulas for the remaining trials.

12. After filling in the formulas for 1000 trials, you can use Excel's AVERAGE function to find the average total project completion time across all trials.

Angles Formulas at the center of a circle can be expressed as:

Central angle, θ = (Arc length × 360º)/(2πr) degrees

Sum of Interior angles=180°(n-2)

The angles formulas are used to find the measures of the angles. An angle is formed by two intersecting rays, called the arms of the angle, sharing a common endpoint.

The corner point of the angle is known as the vertex of the angle. The angle is defined as the measure of the turn between the two lines.

There are various types of formulas for finding an angle; some of them are the central angle formula, double-angle formula, etc...

We use the central angle formula to determine the angle of a segment made in a circle.

If Danielle uses her coupon, she will be able to get the third pair of jeans for free, as long as its value is equal to or lesser than the other two pairs. Let's calculate the total cost for all three pairs of jeans.

Pair 1: $45.00, Pair 2: $39.50, Pair 3: $57.00. To determine the total cost, we need to consider the two most expensive pairs, as Danielle will only pay for those. The two most expensive pairs are Pair 1 and Pair 3. Pair 1 costs $45.00 and Pair 3 costs $57.00.Total cost for the two most expensive pairs: $45.00 + $57.00 = $102.00. Since Danielle receives the third pair for free, she does not have to pay anything extra for it. Therefore, her total cost for all three pairs of jeans, after applying the coupon, is $102.00.

It's important to note that the value of the free pair of jeans cannot exceed the value of the two most expensive pairs. In this case, the total cost is determined by the sum of the two most expensive pairs.

To test the claim that the standard deviation of waiting times in a bank, where customers enter a single waiting line that feeds three teller windows, is less than 1.7 minutes (the standard deviation of waiting times when separate waiting lines are used), a hypothesis test can be conducted.

With a significance level of 0.025, the sample data will be analyzed to calculate the test statistic and compare it to the critical value. If the test statistic falls in the rejection region, the claim that the standard deviation is less than 1.7 minutes can be supported.

To test the claim, a hypothesis test can be performed. The null hypothesis (H0) states that the standard deviation of waiting times in the bank (when customers enter a single waiting line) is not less than 1.7 minutes. The alternative hypothesis (Ha) states that the standard deviation is indeed less than 1.7 minutes.

Next, the sample data will be analyzed to calculate the test statistic. The sample standard deviation will be computed, and the test statistic, such as the z-score or t-score, will be calculated using the sample size and the hypothesized standard deviation of 1.7 minutes. By comparing the test statistic to the critical value obtained from the significance level of 0.025 (considering a one-tailed test), the decision will be made whether to reject or fail to reject the null hypothesis.

If the test statistic falls in the rejection region (i.e., the calculated test statistic is smaller than the critical value), the null hypothesis will be rejected, and there will be evidence to support the claim that the standard deviation of waiting times is less than 1.7 minutes. Conversely, if the test statistic does not fall in the rejection region, there will not be enough evidence to support the claim.

The probability, written as a percent, that an employee is guilty given a positive test result depends on the sensitivity and specificity of the test, as well as the prevalence of guilt in the population.

To determine the probability that an employee is guilty given a positive test result, we need to consider the sensitivity and specificity of the test, along with the prevalence of guilt in the population.

The sensitivity of a test refers to its ability to correctly identify positive cases. A higher sensitivity means that the test is more likely to correctly identify guilty employees. The specificity of a test, on the other hand, indicates its ability to correctly identify negative cases. A higher specificity means that the test is more likely to correctly identify innocent employees.

Additionally, the prevalence of guilt in the population plays a crucial role. If the prevalence of guilty employees is low, even a highly specific test may produce a relatively low probability of guilt given a positive result.

Without information on sensitivity, specificity, and prevalence, it is not possible to provide an accurate numerical answer. It is important to consider these factors when interpreting the results of a test and assessing the probability of guilt in a specific scenario.

Answer:

-28

Step-by-step explanation:

Simplifying

3m + 6 + -2m = -22

Reorder the terms:

6 + 3m + -2m = -22

Combine like terms: 3m + -2m = 1m

6 + 1m = -22

Solving

6 + 1m = -22

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + 1m = -22 + -6

Combine like terms: 6 + -6 = 0

0 + 1m = -22 + -6

1m = -22 + -6

Combine like terms: -22 + -6 = -28

1m = -28

Divide each side by '1'.

m = -28

Simplifying

m = -28

The probability of getting a spade, P(Spade), is 13/52 or 0.2500.

The probability of getting a club, P(Club) = 13/52 or 0.2500.

Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

For instance, if you flip a coin 100 times, you have a 50% chance of getting heads, thus you should anticipate 50 heads. But when we actually test it, we may get 48 heads, 55 heads, or anything else at all, though it will typically be a figure close to 50.

We have a total of 52 cards in the deck.

So, the total number of outcomes = 52

Total number of spades cards = 13

Total number of clubs = 13

So, the sample space would be 13

The probability of getting a spade P(Spade) =13/52 = 0.2500

Similarly, The probability of getting a club P(Club) =13/52 = 0.2500
