Answer: 360000m

Step-by-step explanation:

Okay, so since we know that this train’s speed is 200km/h, let’s find the time difference between 12 24 and 14 12.

14 12 - 2hrs = 12 12

12 12 + 12min = 12 24

2hrs -12min = 1hr 48 min

1hr 48 min also equals to 1.8hrs in decimals. So:

200km x 1.8 = 360km

Now we have to find the answer in meters. Since 1km is equal to 1000m,

That means 360km equals 360000m.

Therefore 360000m is the answer

The sample size needed is 1068. Therefore, the chamber of commerce in the beach resort town should survey at least 1068 visitors to estimate the proportion of repeat visitors to within 0.03 percentage points with 95% confidence.

To calculate the sample size needed, we can use the formula n = (z^2 * p * q) / e^2, where:

n is the sample size

z is the z-score corresponding to the desired confidence level (1.96 for 95% confidence)

p is the estimated proportion of repeat visitors (0.5)

q is the complementary proportion (1-p)

e is the desired margin of error (0.03%)

Plugging in the values, we get:

n = (1.96^2 * 0.5 * 0.5) / 0.03^2 = 1067.11, which we round up to 1068.

The sample size needed for a survey depends on several factors, including the desired level of confidence, the margin of error, and the estimated proportion in the population. In this case, the chamber of commerce wants to be 95% confident that their estimate of the proportion of repeat visitors is accurate within 0.03 percentage points. This means they are willing to accept a maximum error of 0.03 percentage points in either direction from the true proportion, and they want to be confident that their estimate falls within that range. Based on previous experience, they estimate that the proportion of repeat visitors is around 0.5, which is used in the formula to calculate the sample size. The resulting sample size of 1068 should provide the desired level of accuracy and confidence.

One-way ANOVA is a statistical procedure that is used for comparing the means of several populations. Also, it is the generalization of pooled t-procedure for comparing the means of two populations.

A mean is also referred to as an arithmetic average and it can be defined as a ratio of the sum of the total number in a data set (population) to the frequency of the data set.

ANOVA is an abbreviation for analysis of variance which was developed by the notable statistician Ronald Fisher. The analysis of variance (ANOVA) is a collection of statistical models with their respective estimation procedures that are used for the analysis of the difference between the group of means found in a sample.

This ultimately implies that, the analysis of variance (ANOVA) helps to ensure we have a balanced data by splitting the observed variability of a data set into random and systematic factors.

In Statistics, the analysis of variance (ANOVA) procedure is typically used as a statistical tool to determine whether or not the means of two or more populations are equal, especially through the use of the following:

In this context, we can infer and logically deduce that a one-way ANOVA is a statistical procedure that is used for comparing the means of several populations. Also, it is the generalization of pooled t-procedure for comparing the means of two populations.

Here, r is the distance from the pivot point O to the mass, which is equal to the length of the rod (2.2 m). The rod is horizontal and the bearing is frictionless, meaning that there are no additional forces acting on the system that would affect the moment of inertia.




So, for the given scenario:
I = m * (2.2)^2
Without knowing the mass (m), I cannot provide a numerical value for the moment of inertia. However, once you know the mass, you can plug it into the formula above to calculate the moment of inertia about point O.
The moment of inertia i about o can be calculated using the formula i = (1/3) * m * L^2, where m is the mass of the object attached to the end of the rod, and L is the length of the rod. Since the rod is light and of negligible mass, we can assume that m = 0. Therefore, i = 0.

The terms "horizontal" and "frictionless" in the problem indicate that there is no external force acting on the rod and the bearing is not providing any resistance to the motion of the rod. This means that the rod will remain in a horizontal position and will not experience any frictional forces.

The term "inertia" refers to the tendency of an object to resist changes in its state of motion. In this case, the rod will resist any attempt to move it from its horizontal position due to its inertia.
Hi! To determine the moment of inertia (I) about point O for a light rod of negligible mass and length 2.2 m with a mass (m) attached at the end, you should use the following formula for a point mass:
I = m * r^2

If it has a 15% yearly interest rate and the interest is compounded monthly and the card has $0 minimum payments for the first four years it is active. Therefore, Emma will owe approximately $529.27 in four years.

To calculate how much Emma will owe in four years, we need to use the compound interest formula: A = P (1 + r/n)^(n*t)

where:

A = the amount of money at the end of the investment period

P = the principal amount (the initial amount of money borrowed)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period in years

In this case, the principal amount is $300, the annual interest rate is 15%, and the interest is compounded monthly (so n = 12). The time period is four years.

Plugging in the values, we get:

A = 300(1 + 0.15/12)^(12*4)

A ≈ $529.27

Therefore, Emma will owe approximately $529.27 in four years if she doesn't pay off her credit card until after college.

Answer:

The probability Mike Fishman completed the assignments is 0.8780.

Step-by-step explanation:

Note: The question is not complete but the complete one is given as follows:

Dr. Barton has been teaching basic statistics for many years. He knows that 80 percent of the students will complete the assigned problems. He has also determined that among those who do complete the assignment, 90 percent will pass the course. Among these students who do not complete their assignments, 50 percent will pass. Mike Fishman took statistics last semester from Dr. Barton and received a passing grade. What is the probability he completed the assignments?

The following are now the explanation to the answer:

Let A denote the event that the assignment will be completed by the students, B denote the event that the assignment will not be completed by the students, and C denote the event that the test will be passed; the probability that Mike Fishman completed the assignments can be estimated using the following formula:

P(A|C) = P(A)P(C|A) / [P(A)P(C|A) + P(B)P(C|B)] .................. (1)

Where,

P(A|C) = The probability that Mike Fishman completed the assignments = ?

P(A) = Percentage of the students who will complete the assigned problems = 80%, or 0.80

P(B) =  Percentage of the students who will not complete the assigned problems = 100% - 80% = 20%, or 0.20

P(C|A) = Percentage of students who do complete the assignment and pass the course = 90%, or 0.90

P(C|B) = Percentage of students who do not complete the assignment but pass the course = 50%, or 0.50

Substituting all the values into equation (1), we have:

P(A|C) = 0.80 * 0.90 / [(0.80 * 0.90) + (0.20 * 0.50)]

P(A|C) = 0.72 / (0.72 + 0.10)

P(A|C) = 0.72 / 0.82

P(A|C) = 0.8780

Therefore, the probability he completed the assignments is 0.8780.

f(x) = 0.7ˣ where y = f(x).

So y = 0.7ˣ

Taking In on both side,

Iny = x In(0.7)

Divide by In(0.7) on both side, we get

x = Iny/In(0.7)

f⁻¹(y) = Iny/In(0.7)

f(x) = 4.5(2.7)ˣ where y = f(x).

So y = 4.5(2.7)ˣ

Divide by 4.5 on both side, we get

y/4.5 = (2.7)ˣ

Taking In on both side,

In(y/4.5) = In(2.7)ˣ

Iny - In(4.5) = xIn(2.7)
