if someone else collected a different sample from your population and measured the same variable, would they calculate the same sample statistic?

Answers

It is possible that someone else collecting a different sample from the same population and measuring the same variable would calculate the same sample statistic, but it is not guaranteed.

What is meant by Sample Statistic?

Statistical measures that are derived from samples of data rather than the complete population are called sample statistics. A population parameter, such the mean or standard deviation, is estimated using this method. Depending on the type of data and the research issue being examined, sample statistics can be estimated using a variety of formulae and techniques. For instance, to get the sample mean, multiply the sum of all the observations in the sample by the total number of observations. The sample standard deviation is calculated by taking the square root of the sum of the squared differences between each observation and the sample mean. In research studies and surveys, sample statistics are frequently utilized to draw conclusions about the population.

For a resction of the type {A}_{2}(g)+{B}_{2}(g)-2 {AB}(g) with the rate law: -\frac{{d}\left{A}_{2}\right]}{{dt}}={k}\left{A}_{2}\ri

Answers

The rate of the resection reaction is directly proportional to the concentration of N2. As the concentration of N2 decreases, the rate of the reaction also decreases.

The given reaction is a resection reaction, specifically the reaction between A2 and B2 to form 2AB. The rate law for this reaction is represented by the equation:
-\frac{{d}\left[A_{2}\right]}{{dt}}=k[A_{2}]

In this equation, [A2] represents the concentration of A2, t represents time, and k is the rate constant.
The negative sign indicates that the concentration of A2 decreases over time. The rate constant, k, is a proportionality constant that determines the rate at which the reaction occurs.

To understand the meaning of this rate law, let's break it down step by step:
1. The rate of the reaction is directly proportional to the concentration of A2. This means that as the concentration of A2 increases, the rate of the reaction also increases.
2. The negative sign indicates that the concentration of A2 decreases over time. This suggests that A2 is being consumed during the reaction.
3. The rate constant, k, represents the speed at which the reaction occurs. A higher value of k means a faster reaction, while a lower value of k means a slower reaction.

Let's consider an example to illustrate this rate law:

Suppose we have a reaction between nitrogen gas (N2) and hydrogen gas (H2) to form ammonia gas (NH3). The balanced chemical equation for this reaction is:
N2(g) + 3H2(g) -> 2NH3(g)

The rate law for this reaction could be written as:
-\frac{{d}\left[N2\right]}{{dt}}=k[N2]
In this case, the rate of the reaction is directly proportional to the concentration of N2. As the concentration of N2 decreases, the rate of the reaction also decreases.

lots of Kelsey's number.
3 lots of Ronan's number added to Kelsey's
number is 97.
Using the information above, write and
solve two simultaneous equations to work
out Ronan and Kelsey's numbers.

Answers

The 2 equations which can be used to solve the given situations of the numbers are:

x - 2 = 4x3x + x = 97

What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. As in 3x + 5 Equals 15, for instance. Equations come in a variety of forms, including linear, quadratic, cubic, and others. The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

So, the equations that can be formed are:

Let, Ronan's number be 'x' and '4x' be Kelsey's number.

(1) x - 2 = 4x

Now, solve as follows:

4x - x = -23x = -2x = -2/3

Ronan's number be: -2/3

Kelsey's number be: 4 × 2/3 = -8/3

Let, let, Kelsey's number be 'x' and Ronan's number be '3x'.

(2) 3x + x = 97

Now, solve as follows:

4x = 97x = 97/4x = 24.25

Ronan's number be: 72.75

Kelsey's number be: 24.25

Therefore, the 2 equations which can be used to solve the given situations of the numbers are:

Your answer should be in the form p(x) + k/x-1 where P is a polynomial and k is an integer
x^2+2/x-1=

Answers

The answer in the form of polynomial is:

x² + 2/(x-1) = x + 3 + 1/(x-1)

What is polynomial?

An expression that consists of variables, constants, and exponents and that is combined using mathematical operations such as addition, subtraction, multiplication, and division (no division operation by a variable) is referred to as a polynomial.

To write x² + 2/(x-1) in the form of p(x) + k/(x-1), we need to perform partial fraction decomposition:

x² + 2/(x-1) = (Ax + B)/(x-1) + Cx + D

Multiplying both sides by (x-1), we get:

x² + 2 = (Ax + B) + (Cx + D)(x-1)

Expanding the right-hand side, we get:

x² + 2 = Ax + B + Cx² - Cx + Dx - D

Matching coefficients on both sides, we get the following system of equations:

C = 1

D - B = 2

A - C = 0

-B + D = 0

Solving for A, B, C, and D, we get:

A = 1

B = -1

C = 1

D = 1

Therefore, we have:

x² + 2/(x-1) = (x-1)/x-1 + x + 1

                   = x + 2 + 1/(x-1)

Hence, the answer is:

x² + 2/(x-1) = x + 3 + 1/(x-1)

Solution,

Given,

Cost for 1 pen = $ 1.50

= 1.50×100 cents

= 150 cents

Cost for 1 ruler = 80 cents

No. of Pens needed to be bought = x

No. of rulers needed to be bought = x+10

Now,

Cost for x pens = x×150 cents

= 150x cents

Cost for (x+10) rulers = (x+10)×80 cents

= 80x cents+800 cents

Then,

Total cost = 150x cents+(80x cents+800 cents)

= 150x cents+80x cents+800 cents

= 230x cents+800 cents

= $(230x ÷ 100)+$(800 ÷ 100)

a baseball player with a career batting average of .300 comes up to bat 75 times in a month. (a) what is the mean number of hits such players should get? (b) what is the standard deviation?

Answers

(a) The mean number of hits a baseball player with a career batting average of .300 should get in 75 at-bats is approximately 22.5 hits.

(b) The standard deviation cannot be determined solely based on the batting average; additional information is required.

(a) The mean number of hits can be calculated by multiplying the batting average (.300) by the number of at-bats (75):

Mean number of hits = Batting average × Number of at-bats = 0.300 × 75 = 22.5 hits.

(b) The standard deviation cannot be determined solely based on the batting average because it only provides information about the average success rate per at-bat. The standard deviation requires additional information, such as the variance or distribution of hits among the at-bats.

James, Priya, and Siobhan work in a grocery store. James makes $9.00 per hour. Priya makes 20% more
than James, and Siobhan makes 5% less than Priya. How much does Siobhan make per hour?

Answers

Priya makes $10.8
Siobhan makes $10.26

Answer:

Step-by-step explanation:

Don't be too quick to answer 15% of some number. It may be right, but it is likely not.

James makes 9.00 dollars an hour

Priya makes 20% more than James. Stop. Figure that out.

9.00 * 1  + 25/100 * 9 = 9.00 + 2.25 = 11.25

Now, you can figure out 5% less.

Siobhan = 11,25 - 5/100 * 11.25

Siobhan = 11.25 - 0.05 * 11.25

Siobhan = 11.25 - 0.5625

Siobhan = 10.6875 = 10.69

There is no other way that I know of to go directly to Siobhan's wage other than doing it the long way -- at least for the level of math you are taking.

9 * (1.2 - 0.05) might work.

The proof of the congruent sides RU and TS is given below.

What is congruent triangles?

In any orientation, two triangles are said to be congruent if their three sides and three angles are equal.

Therefore, if two triangles have the same number of sides on each side, they are said to be congruent. Additionally, we can determine that they are congruent if we have a side, an angle between the sides, and then another side that is congruent, in that order: side, angle, side.

Let the given figure is a rectangle RSTU.

Since the all four angles of rectangle are of 90 degree.

So, each angle of rectangle RSTU is 90 degree.

Let, US divides the angle RUT and angle RST and form two new triangles, ΔSRU and ΔSTU.

Both the triangles having same measure of angles and sides.

⇒  ΔSRU ≅ ΔSTU

As the triangles are congruent so their sides are congruent.

In a university, if a student is a business major, then there is 70% chance that he/she will be employed immediately after graduation. And if a student is not a business major, then there is a 35% chance that hel she will be employed immediately after graduation. We also know that 40% of students are business majors and 60% of students are not business majors. What is the probability that a student is a business major given that he or she is employed immediately after graduaton?

Answers

To find the probability that a student is a business major given that they are employed immediately after graduation, we can use Bayes' theorem:

P(Business Major | Employed) = P(Employed | Business Major) * P(Business Major) / P(Employed)

We are given the following probabilities:

P(Employed | Business Major) = 0.70
P(Business Major) = 0.40
P(Employed | Not Business Major) = 0.35
P(Not Business Major) = 0.60

First, we need to find the probability of being employed (P(Employed)):

P(Employed) = P(Employed | Business Major) * P(Business Major) + P(Employed | Not Business Major) * P(Not Business Major)

P(Employed) = (0.70 * 0.40) + (0.35 * 0.60) = 0.28 + 0.21 = 0.49

Now, we can use Bayes' theorem to find the probability that a student is a business major given that they are employed immediately after graduation:

P(Business Major | Employed) = (0.70 * 0.40) / 0.49 ≈ 0.5714

So, the probability that a student is a business major given that they are employed immediately after graduation is approximately 57.14%

a. The null hypothesis for this test is that all colors are equally likely for Milk Chocolate M&M's, while the alternative hypothesis is that the colors are not equally likely.

b. If all colors are equally likely, we would expect to see 70 candies of each color in a bag of 420 candies.

c. Yes, a chi-square test is appropriate.

d. The degree of freedom for 5 is 5

e. The chi-square test statistic is 24.6

f. The p-value for your test is 11.070

g. The color that contributes the most to the chi-square test statistic is brown, with an observed count of 47 and an expected count of 70.

a. The null hypothesis for this test is that all colors are equally likely for Milk Chocolate M&M's, while the alternative hypothesis is that the colors are not equally likely.

b. If all colors are equally likely, we would expect to see 70 candies of each color in a bag of 420 candies. This is because there are six colors, and

=>  420 / 6 is =  70.

c. Yes, a chi-square test is appropriate in this situation because we are comparing observed frequencies (the actual number of candies of each color in the bag) to expected frequencies (the number of candies we would expect to see if all colors are equally likely).

d. There are 5 degrees of freedom in this situation. This is because we have 6 colors, but we can only choose 5 of them freely. Once we know the frequency of 5 colors, we can determine the frequency of the 6th color.

e. To calculate the chi-square test statistic, we need to find the sum of

=> ((observed frequency - expected frequency)² / expected frequency)

for each color.

Using the data provided, we get a chi-square test statistic of 24.6 (rounded to three decimal places).

f. To find the p-value for our test, we need to compare our chi-square test statistic to a chi-square distribution table with 5 degrees of freedom. At a 5% significance level, our critical value is 11.070. Since our test statistic (24.6) is greater than the critical value (11.070), we can reject the null hypothesis and conclude that the colors are not equally likely for Milk Chocolate M&M's.

g. The color that contributes the most to the chi-square test statistic is brown, with an observed count of 47 and an expected count of 70. This means that there were fewer brown M&M's in the bag than we would expect if all colors were equally likely.

Which of the following types of harm resulting from technological innovations can engineers be held most morally blameworthy? O Foreseen harms O Foreseeable harms O Unforeseen harms O Unforeseeable harms

Answers

Engineers can be held most morally blameworthy for foreseeable harms resulting from technological innovations, engineers have a responsibility to anticipate the potential consequences of their work,

and to take steps to mitigate those consequences. If they fail to do so, and their work results in harm, they can be held morally blameworthy. When engineers develop new technologies, they have a responsibility to consider the potential consequences of their work.

They need to think about how their technology could be used, and whether it could be used to harm people or the environment.

They also need to consider how their technology could be misused, and what steps they can take to prevent misuse.

If engineers fail to consider the potential consequences of their work, and their work results in harm, they can be held morally blameworthy. This is because they have a duty to protect the public from harm, and they have failed to fulfill that duty.

For example, engineers who develop new weapons systems have a responsibility to consider the potential consequences of their work. They need to think about how their weapons could be used,

and whether they could be used to kill or injure innocent people. They also need to consider how their weapons could be misused, and what steps they can take to prevent misuse.

If engineers fail to consider the potential consequences of their work, and their weapons are used to kill or injure innocent people, they can be held morally blameworthy. This is because they have a duty to protect the public from harm, and they have failed to fulfill that duty.

It is important to note that engineers cannot be held morally blameworthy for unforeseeable harms. This is because they did not have the opportunity to anticipate the harm, and they could not have taken steps to prevent it.

For example, engineers who develop new medical treatments cannot be held morally blameworthy if the treatments have unforeseen side effects. This is because the engineers did not have the opportunity to anticipate the side effects, and they could not have taken steps to prevent them.

In conclusion, engineers can be held morally blameworthy for foreseeable harms resulting from technological innovations.

This is because they have a responsibility to anticipate the potential consequences of their work, and to take steps to mitigate those consequences.
