One morning, Adrian stood tall and had a friend measure his shadow on the sidewalk. Adrian's friend also measured from the top of Adrian's head to the tip of his shadow. The diagram below shows these measurements. How tall is Adrian? A 4.5 ft B 5 ft C 5.5 ft D 6 ft

Answers

The length of Adrian's shadow measured by his friend and the distance directly from Adrian's head to the tip of his shadow can be used to find Adrian's height using Pythagorean Theorem. Using an example of the measurement values, Adrian's height is about 5.5 feet

What is Pythagorean Theorem?

Pythagorean Theorem states that the sum of the square of the lengths of the legs of a right triangle is equal to the square of the length of the hypotenuse side.

The diagram in the question appears left out. Please find attached a drawing made using the measurement lengths in the following example, created with MS Word.

The measurements Adrian had his friend to do are;

The length of Adrian's shadow on the sidewalk and the length from Adrian's head to the tip of the shadow.

Let x represent the length of Adrian's shadow, let r represent the distance from Adrian's head to the tip of the shadow, and let y represent Adrian's height

According to Pythagorean Theorem, we get;

r² = x² + y²

Therefore, the Adrian's height, h = √(r² - x²)

When r ≈ 8.14, and x = 6, we get;

h = √(8.14² - 6²) ≈ 5.5

Adrian's height is about 5.5 feet in the example situation

An independent-measures study with n = 6 in each sample produces a sample mean difference of 4 points and a pooled variance of 12. what is the value for the t statistic?

Answers

The value of t statistic for independent measures is option B: 2.00 by calculations using the formula, t = (X1 - X2) / (SE).

The formula for the t statistic for independent measures is given by:

t = (X1 - X2) / (SE)

where X1 - X2 is the difference between the means of two independent samples, SE is the standard error of the difference between means.

We have already been given that n = 6 in each sample produces a sample mean difference of 4 points and a pooled variance of 12, and a standard error of the mean difference of 2, we can calculate the t statistic as follows:

t = (4) / (2) (Because X1 - X2 =4)

Step-by-step explanation:

You need to add all the socks to get the total amount of socks:

4 Black Pairs + 5 Red Pairs + 15 White Pair = 24 Total Pairs.

Next you need to find the probability of pulling a white pair so you divide the amount of white pairs to the total pairs of socks.

15 / 24 = 0.625 %

what if you are asked to find n-1 numbers such that their sum is x? can you find it in polynomial time? if so, what is your solution and the running time? if not, why not. you may assume that you can add any two numbers in constant time.

Answers

It is unlikely that an algorithm for finding n-1 numbers such that their total equals x exists in polynomial time because the Subset Sum problem is NP-complete.

Finding a subset of n integers such that their total equals x from a given set of n-1 numbers are identical to the task at hand. Unfortunately, there is no known polynomial-time solution for solving this problem, which is also known as the Subset Sum problem and is a well-known NP-complete problem.

Consider the following reduction from the Subset Sum problem to understand why this is the case: Create a new set S' by adding a single element x to the original set S after receiving a Subset Sum problem instance consisting of a set S of n integers and a goal sum x.

Take into account the reduction from the Subset Sum problem to see why this is the case: Create a new set S' by adding a single element x to the existing set S in a case of the Subset Sum problem where the inputs are a set S of n integers and a goal sum x.

Two machines in a car parts factory mold different parts that will eventually be put together in an assembly plant. the first machine makes a part every 12 seconds, and the second machine makes a part every 45 seconds. the quality control engineer tests these parts each time they both come out of the machines at the same time. how often does she test the parts? show your work and express your answer in minutes.

Answers

The quality control engineer will test the parts every 3 minutes.

To determine how often the quality control engineer tests the parts, we need to find the least common multiple (LCM) of the time it takes for the first machine to make a part and the time it takes for the second machine to make a part.
The first machine makes a part every 12 seconds, while the second machine makes a part every 45 seconds.
To find the LCM, we can list the multiples of each number and look for the smallest number that appears in both lists:
Multiples of 12: 12, 24, 36, 48, 60, 72, ...
Multiples of 45: 45, 90, 135, 180, 225, 270, ...
From the lists above, we can see that the smallest number that appears in both lists is 180.
Therefore, the quality control engineer will test the parts every 180 seconds.
To express the answer in minutes, we can convert 180 seconds to minutes:
180 seconds ÷ 60 = 3 minutes

an emergency room nurse believes the number of upper respiratory infections is on the rise. the emergency room nurse would like to test the claim that the average number of cases of upper respiratory infections per day at the hospital is over 21 cases. using the computed test statistic of 2.50 and the critical value of 2.33, is there enough evidence for the emergency room nurse to reject the null hypothesis?

Answers

To determine whether there is enough evidence to reject the null hypothesis, we need to compare the computed test statistic to the critical value.

In this case, the computed test statistic is 2.50 and the critical value is 2.33. If the computed test statistic falls in the rejection region beyond the critical value, we can reject the null hypothesis. Conversely, if the computed test statistic falls within the non-rejection region, we fail to reject the null hypothesis.In this scenario, since the computed test statistic (2.50) is greater than the critical value (2.33), it falls in the rejection region. This means that the observed data is unlikely to occur if the null hypothesis were true.

Therefore, based on the given information, there is enough evidence for the emergency room nurse to reject the null hypothesis. This suggests that there is sufficient evidence to support the claim that the average number of cases of upper respiratory infections per day at the hospital is over 21 cases.

https://brainly.com/question/15525560

#SPJ11

Final answer:

There is enough evidence to reject the null hypothesis in this case because the computed test statistic (2.50) is higher than the critical value (2.33). This suggests the average number of daily respiratory infections exceeds 21, providing substantial evidence against the null hypothesis.

Explanation:

Yes, there is enough evidence for the emergency room nurse to reject the null hypothesis. The null hypothesis is typically a claim of no difference or no effect. In this case, the null hypothesis would be an average of 21 upper respiratory infections per day. The test statistic computed (2.50) exceeds the critical value (2.33). This suggests that the average daily cases indeed exceed 21, hence providing enough evidence to reject the null hypothesis.

It's crucial to understand that when the test statistic is larger than the critical value, we reject the null hypothesis because the observed sample is inconsistent with the null hypothesis. The statistical test indicated a significant difference, upheld by the test statistic value of 2.50. The significance level (alpha) of 0.05 is a commonly used threshold for significance in scientific studies. In this context, the finding suggests that the increase in respiratory infection cases is statistically significant, and the null hypothesis can be rejected.

(b) A = the set of all words of English, R = {(x, y) ∈ A × A | the first letter of the word y occurs at least as late in the alphabet as the first letter of the word x}.
(c) A = the set of all countries in the world, R = {(x, y) ∈ A × A | the population of the country y is at least as large as the population of the country x}

Answers

(a) In the case where A is the set of all words of English and R is defined by the alphabetical order, R is a partial order on A. This is because R meets the criteria for a partial order: reflexivity, antisymmetry, and transitivity.

However, R is not a total order, as some words may not be directly comparable, such as words starting with the same letter.

(b) When A is the set of all words of English and R is defined by the first letter's alphabetical order, R is again a partial order on A.

It meets the same criteria as mentioned before: reflexivity, antisymmetry, and transitivity. But it is not a total order, as words with the same first letter cannot be compared based on this relation.

(c) For A being the set of all countries and R defined by population, R is a partial order on A. The criteria for reflexivity, antisymmetry, and transitivity are met as well.

However, R is not a total order since countries with the same population size cannot be compared.

In summary, all three cases exhibit partial orders on A, but none of them represent total orders.
