Answer:

135. You multiply to get your answer.

The worth of the game remains at 3.5 dollars. The second roll is the only one that matters, the expected value is now equal to the average value of a single roll,

a) In the first scenario, where you roll a die and are given an amount in dollars equal to the number on the die, the expected value of the game can be calculated by taking the average of all possible outcomes.

Since the die has six sides and each side is equally likely to come up, the expected value is calculated as (1/6 * 1) + (1/6 * 2) + (1/6 * 3) + (1/6 * 4) + (1/6 * 5) + (1/6 * 6) = 3.5 dollars.

Therefore, if you played this game a lot of times, you would expect to pay an average of 3.5 dollars per game.

b) In the second scenario, where you have the option to roll a second time and are obligated to take the number of dollars from the second roll, the expected value changes. Let's analyze the possible outcomes:

- If you decide to take the money from the first roll, the expected value is the same as in the previous scenario, which is 3.5 dollars.
- If you decide to roll a second time, the expected value is again calculated by taking the average of all possible outcomes.

However, since the second roll is the only one that matters, the expected value is now equal to the average value of a single roll, which is (1/6 * 1) + (1/6 * 2) + (1/6 * 3) + (1/6 * 4) + (1/6 * 5) + (1/6 * 6) = 3.5 dollars.


The worth of the game in the second scenario is the maximum value between the expected value of taking the money from the first roll (3.5 dollars) and the expected value of rolling a second time (3.5 dollars).

Therefore, the worth of the game remains at 3.5 dollars.

The worth of the game depends on the scenario. In the first scenario, where you only roll once, the worth is around 3.5 dollars. In the second scenario, where you have the option to roll a second time, the worth is less than 2 dollars.

a) If you roll a die and are given an amount in dollars equal to the number on the die, the expected value of this game can be calculated by taking the average of the possible outcomes. Since there are six possible outcomes (numbers 1 to 6), the expected value is the sum of these outcomes divided by 6.

The expected value is (1+2+3+4+5+6) / 6 = 3.5 dollars.

To find what you would pay to play this game, you would ideally want to pay an amount less than the expected value to make it a profitable game. However, if you played this game a lot of times, the law of large numbers suggests that your average outcome will approach the expected value. Therefore, it would be reasonable to pay around 3.5 dollars to play this game.

b) In the second scenario, if you roll the die and have the option to either take the money from the first roll or roll a second time and take the second roll's amount, the expected value changes. Now, you have a 1/6 chance of getting each number from the first roll and a 1/6 chance of getting each number from the second roll.

To calculate the expected value, you need to consider both possibilities. You would calculate the average of the outcomes from the first roll and the outcomes from the second roll, and then take the maximum of these two values.

For example, if you roll a 1 on the first roll, the expected value from the first roll would be 1. If you roll a 2 on the second roll, the expected value from the second roll would be 2. The maximum of these two values is 2. Therefore, the expected value for this game is 2 dollars.

When deciding what this game is worth, you would want to pay an amount less than the expected value to make it profitable. So, in this scenario, you would ideally want to pay less than 2 dollars to play this game.

Now, she gave 1/6 of the bread to EACH of her 3 friends.

So you will need to do 1/6*3, which is 3/6=1/2.

Now you want to do 1/8+1/2 = 1/8+4/8 = 5/8.

This means 5/8 of the bread is gone.

Now you will need to do 1-5/8 = 8/8-5/8=3/8.

Therefore, 3/8 of the bread is left.

The probability that the firm receives 2 or more complaints in a day is 0.33.

This can be calculated using the Poisson distribution formula. The Poisson distribution is a probability distribution used to calculate the probability of an event occurring a given number of times in a fixed interval of time or space.

It is based on the assumption that the rate of occurrence of an event is constant.

In this case, we are looking at the probability of the firm receiving 2 or more complaints in a day. Let x = 2, where x is the number of complaints in a day. Then, the Poisson distribution formula is: P(x) = (e-λ λx) / x!

Where e = 2.71828 and λ = 3 (the rate of complaints per day).

Plugging in the values, we get: P(2) = (2.71828-3 * 32) / 2! = 0.33. Therefore, the probability that the firm receives 2 or more complaints in a day is 0.33.

The minimal amount of work the bird can expend to break open a whelk shell can be found by minimizing the function 27 + 1)hw(h) = -0.51.

To find the minimal value, we need to find the minimum value of the function w(h). Since no specific equation for w(h) is provided, we can assume that w(h) is a linear function of h.

Let's rewrite the given equation in a more simplified form:

w(h) = -0.51 / (27 + 1)h

To find the minimum value of w(h), we need to find the maximum value of the denominator, (27 + 1)h.

The maximum value of the denominator occurs when h is at its highest possible value. However, no information about the maximum height is given in the problem.

Therefore, without further information about the range of values for h, we cannot determine the minimal amount of work the bird can expend to break open a whelk shell.

As a result, none of the options provided (28.7, 25.5, 34.9, 16.6) can be conclusively determined to be the minimal amount of work.

The correct answer is Yes, past age 85 years of age, for every 100 men, there are 200 women.

Given,

In the question:

Your grandmother is 87 years old and she has remarked to you that nearly all of her friends are women. She told you that it is rare to see a man older than age 85. She is correct because, after age 85, for every 100 men, there are __________.

Now, According to the question:

Your grandmother is 87 years old and she told you that all of her friends are women. There is no single man in her circle of friends. She also told that it is rare to see a man over the age of 85. It is because of the fact that women are more in number than man above the age of 85 and this ratio is like 100 men per 200 women, which means the chances of getting a male friend is almost half after the age of 85. So women are more in number than men.

Hence, The correct answer is Yes, past age 85 years of age, for every 100 men, there are 200 women.

The probability of at least one of your 10 lottery tickets being a winner is approximately 0.638 or 63.8%.

The probability of winning on a single lottery ticket is 1/8, which means that the probability of not winning is 7/8. If you buy 10 of these lottery tickets, the probability of not winning on any of them is:

(7/8)^10 = 0.362

This means that there is a 36.2% chance that none of your tickets will be a winner. To find the probability that at least one of your tickets will be a winner, we can use the complementary probability:

P(at least one winner) = 1 - P(no winners)

P(at least one winner) = 1 - 0.362

The test statistic for a sample with correlation coefficient r = 0.5 and sample size n = 30 is 3.06.

To test whether a correlation is significant, we need to calculate the test statistic using the correlation coefficient (r) and the sample size (n). The formula for the test statistic is:

t = r * sqrt(n-2) / sqrt(1-r^2)
Here, r is the correlation coefficient (0.5) and n is the sample size (30).
Plugging in the given values of r = 0.5 and n = 30, we get:

t = 0.5 * √((30 - 2) / (1 - 0.5^2))
t = 0.5 * √(28 / 0.75)
t = 0.5 * √(37.33)
t = 0.5 * 6.11
t ≈ 3.06

Thus, the test statistic for this sample is approximately 3.06. To determine whether the correlation is significant, we would need to compare this test statistic to a critical value from a t-distribution with n-2 degrees of freedom at the desired significance level.

The distance between the boat and Johnstown is changing at a rate of 27.73 miles per hour.

This is calculated by taking the speed of the boat (30 miles per hour) and subtracting the rate of change in the boat's displacement in a southward direction, which is 2.27 miles per hour (calculated by taking the distance travelled (126 miles) and dividing it by the time taken (126/30 = 4.2 hours)).

Distance is a measure of how far something is from a given point, while velocity is a measure of the rate at which something changes its position or moves. Distance is a scalar quantity, meaning it has only magnitude and no direction, while velocity is a vector quantity, meaning it has both magnitude and direction.
