The average of height of x girls and y boys with m and n height is (mx + ny)/(x + y).

The average of any value is calculated by the formula -

Average = sum of the height of students ÷ total number of students

Based on mentioned information, the average can be calculated through individually calculating numerator and denominator.

Sum of the heights of girls in a class = m × x

Sum of the height of boys in a class = n × y

Total number of students in a class = x + y

Keep the value in formula -

Average = (mx + ny)/(x + y)

Thus, average height is (mx + ny)/(x + y).

For fixed population standard deviation and level of significance, the minimum sample size needed to guarantee a given margin of error decreases as the margin of error increases.

The square root of the variance for the given set of numbers is what the standard deviation examines. It is employed to compute a confidence interval for making judgments (such as accepting or rejecting a hypothesis).

Here, the population standard deviation, and level of significance are the same.

As the margin of error increased.

So, with the increase in the value of the margin of error, there will surely decrease in the value of the sample size

\($$\begin{aligned}&\mathrm{MOE}_\gamma=z_\gamma \times \sqrt{\frac{\sigma^2}{n}}\\&\begin{aligned}\mathrm{MOE} & =\text { margin of error } \\\gamma & =\text { confidence level } \\z_\gamma & =\text { quantile } \\\sigma & =\text { standard deviation } \\n & =\text { sample size }\end{aligned}\end{aligned}$$\)

As the margin of error is in the denominator position in the sample size formula

Hence with an increase in the margin of error sample size decreases.

The posterior probability of the selected individual having the disease given two positive test results is 0.9987. Therefore, the individual most likely has the disease, given the two positive test results.

To solve this problem, we use the Bayes' Theorem.

Bayes' Theorem: P(A|B) = P(B|A) P(A) / P(B),

where: P(A|B) is the probability of event A occurring given that B is true.

P(B|A) is the probability of event B occurring given that A is true.

P(A) is the prior probability of A occurring.

P(B) is the prior probability of B occurring

To solve the problem, we need to compute the posterior probability of having the disease given two positive test results:

P(Disease | 2 positive tests) = P(2 positive tests | Disease) P(Disease) / P(2 positive tests)

where: P(2 positive tests | Disease) is the probability of having two positive tests given the individual has the disease. P(Disease) is the prior probability of the individual having the disease. P(2 positive tests) is the prior probability of having two positive tests.

Let's compute the individual terms: P(Disease) = 0.6 (given in the problem statement)

P(No Disease) = 0.4 (complementary to having the disease)

P(Positive Test | Disease) = 0.94

P(Negative Test | Disease) = 0.06 (complementary to the positive test)

P(Negative Test | No Disease) = 0.97

P(Positive Test | No Disease) = 0.03 (complementary to the negative test)

Using the probability multiplication rule, we can compute:

P(2 Positive Tests | Disease) = P(Positive Test | Disease) * P(Positive Test | Disease) = 0.94 * 0.94 = 0.8836 (probability of having two positive tests given that the individual has the disease)

P(2 Positive Tests | No Disease) = P(Positive Test | No Disease) * P(Positive Test | No Disease) = 0.03 * 0.03 = 0.0009 (probability of having two positive tests given that the individual does not have the disease)

Now, let's use these values to compute the posterior probability of having the disease:

P(Disease | 2 positive tests) = P(2 positive tests | Disease) P(Disease) / P(2 positive tests) = 0.8836 * 0.6 / [0.8836 * 0.6 + 0.0009 * 0.4] = 0.9987

The posterior probability of the selected individual having the disease given two positive test results is 0.9987. Therefore, the individual most likely has the disease, given the two positive test results.

Explanation:

x = amount she travels on each of those three remaining days

3x = total amount traveled over those three remaining days

3x+24 = total amount traveled over the four days

3x+24 = 120 miles total

This equation is in the form px+q = r where:

Let's solve for x. We follow PEMDAS in reverse to undo what's happening to x, so we can isolate it.

3x+24 = 120

3x+24-24 = 120-24 .... subtract 24 from both sides

3x = 96

3x/3 = 96/3 .... divide both sides by 3

x = 32

Triana must travel 32 miles per day for those remaining three days.

Doing so means she travels 3x = 3*32 = 96 miles over those three remaining days. Then add on those 24 miles traveled on the first day to get 96+24 = 120 miles total. This helps confirm the answer.

Another way to confirm the answer is to plug x = 32 into 3x+24 = 120. After simplifying both sides, you should get 120 = 120 which is a true statement.

Fred owes $14,250 in credit card debt.

We must total up all of Fred's assets and liabilities, then subtract them to arrive at the amount he owes on his credit cards.

Let's figure it out:

Total Assets:

House (current value) = $105,900

Checking Account = $375

Vehicle (current value) = $13,500

Savings Account Value = $1,275

Total Liabilities:

Credit Card Debt = ?

Student Loans = $32,000

Personal Loans = $800

Total Assets - Total Liabilities = Net Worth

105,900 + 375 + 13,500 + 1,275 - (Credit Card Debt + 32,000 + 800) = 74,000

Solving for Credit card debt =

Credit Card Debt = 74,000 - 88,250

Credit Card Debt = -14,250 [The negative sign identifies it as a liability, as you can see.]

Therefore, Fred owes $14,250 in credit card debt.

12.5ml of a 60% solution is required to create 50ml of a 15% amount solution. You can compute this using a proportion.

50% x 15% = 7.5 ml, and 7.5 ml x 60% = 12.5 ml

12.5ml of a 60% solution is required to create 50ml of a 15% solution. You can compute this using a proportion. To begin with, we must ascertain how much of the 15% solution is required to make 50ml. To accomplish this, multiply 50 ml by 15%, which yields the answer of 7.5 ml. This means that to make 50ml, 7.5ml of the 15% solution is required. The next step is to calculate how much of the 60% solution is needed to create 7.5ml. To do this, divide 7.5 ml by 60%, which yields the result 12.5 ml.

In single-case designs, the standard for comparison purposes to evaluate the treatment effects is typically the individual's own performance during different phases of the study. Here's a step-by-step explanation:

1. Baseline Phase: The study begins by collecting data on the individual's behavior or performance without any intervention. This phase is called the baseline and serves as a reference point for comparison.

2. Intervention Phase: After establishing the baseline, the researcher introduces the treatment or intervention. The individual's performance during this phase is then compared to their performance during the baseline phase.

3. Reversal or Withdrawal Phase (optional): In some single-case designs, the intervention is withdrawn to see if the individual's performance returns to baseline levels. This phase helps to further establish the treatment's effectiveness.

4. Replication (optional): The study can be replicated with the same individual or with other individuals to demonstrate the treatment's effectiveness across different cases.

By comparing the individual's performance across these different phases, researchers can evaluate the treatment effects without the need for a control group.

Answer:

A. A change B:Atom C:wow

Step-by-step explanation:

Sorry man, its 18 points

(a) The charge on an atom is neutral, meaning that the total number of positive charges from protons is equal to the total number of negative charges from electrons. Hence, the net charge on an atom is zero.

(B) If an atom loses an electron, there will be more protons than electrons in the atom. The atom acquires a general positive charge as a result. For instance, if a sodium atom (Na), which is normally neutral, loses an electron, it changes into the positively charged ion (Na+).
(c) If an atom obtains one electron, there will be more electrons than protons in the atom. This results in an overall negative charge on the atom. For example, if a neutral atom of chlorine (Cl) gets an electron, it forms a negatively charged ion (Cl-) (Cl-).

The probability that Emme answers exactly 3 questions correctly is 0.1961.

Since each question has four answer choices and only one is correct, the probability of Emme randomly guessing the correct answer for each question is 1/4 = 0.25. Emme needs to answer exactly 3 out of the 9 questions correctly, so we use the binomial distribution with n = 9 and p = 0.25 to calculate the probability:

P(X = 3) = (9 choose 3) * (0.25)^3 * (0.75)^6

Using a calculator, we get:

P(X = 3) = 0.1961

Therefore, the probability that Emme answers exactly 3 questions correctly is 0.1961.
