The cost to you of attending the game is $85.

Attending the Cubs game involves an opportunity cost, which is the value of the best alternative forgone when making a decision. In this case, your opportunity cost is the income you would have earned at your part-time job if you had not attended the game.

The game takes five hours, and you would have worked for $12 an hour at your part-time job.

Therefore, the lost income from not working is:

5 hours x $12 = $60.

Additionally, you spent $25 on transportation to attend the game.

To find the total cost of attending the game, you need to consider both the opportunity cost and the direct cost of transportation.

The total cost is:

$60 (lost income) + $25 (transportation) = $85.

In conclusion, the cost to you of attending the game is $85, which includes the $60 opportunity cost of not working at your part-time job and the $25 spent on transportation.

Pythagorean theorem is applied to the right-angled triangle. The length of the two legs of the triangle is 9√2 cm.

Pythagorean theorem helps us to find the hypotenuse of a right-angled triangle with the help of the other two sides of the triangle.

Hypotenuse² = Perpendicular² + Base²

Given to us

A right-angle triangle with angles, 45°- 45°- 90°

Length of the hypotenuse of the triangle, h = 18 cm

As in the given triangle, two of the angles are of equal measure, therefore, the triangle's two legs are of equal length, while the length of the hypotenuse is 18 cm.

AB = AC

Using the Pythagorean theorem,

BC² = AB² + AC²

18² = AB² + AB²

18² = 2 AB²

162 = AB²

AB = 9√2

Hence, the length of the two legs of the triangle is 9√2 cm.

First, we need to choose a woman for the position of president, then another woman for the position of vice president, and finally, a man for the treasurer position.

1. President: Since there are 20 women, we have 20 options for the president position.
2. Vice President: We're left with 19 women (since we already chose one for the president), so we have 19 options for the vice president position.
3. Treasurer: Since there are 17 men, we have 17 options for the treasurer position.

Now, multiply the number of options for each position together to find the total number of ways to form the committee:

20 (president) × 19 (vice president) × 17 (treasurer) = 6,460 ways.

The comparison of two quantities with different units is called a ratio and proportion. A ratio that specifically compares two quantities measured in different units.

Comparing amounts is done using a ratio. A ratio demonstrates how many times one amount fits inside another or how much larger one amount is than another.

If I need to mix some cement, I would add two parts cement to four parts sand. The two numbers are both portions of the entire. Hence, the 2:4 ratio (6 parts in total). The written version is crucial; 4:2 would produce a different blend.

Ratios are expressed in their most basic form. There are five green and fifteen red dots in the figure on the right. The ratio is 15:5, but like with fractions, this can be boiled down to its most basic form.

If you look at the relationship between the numbers 15:5 as is 3:1, you can see that 3 is multiplied by 5 to obtain 15 and that 1 is multiplied by 1 to get 5. The ratio, as we can see in the image, is also 3:1.

Statistical power is a measure of the ability to reject the null hypothesis when it is false. It represents the probability of correctly identifying a true effect or relationship in a statistical hypothesis test.

A high statistical power indicates a greater likelihood of detecting a significant result if the null hypothesis is indeed incorrect. The power of a statistical test depends on several factors, including the sample size, the effect size (the magnitude of the true effect or difference), the chosen significance level (often denoted as α), and the variability or noise in the data. Increasing the sample size or effect size generally increases the statistical power, while a lower significance level or higher variability decreases it.

Power analysis is commonly used to determine an appropriate sample size for a study, ensuring that it is adequately powered to detect the desired effect. A higher power is desirable as it reduces the chances of a Type II error (failing to reject the null hypothesis when it is false) and increases the chances of correctly detecting real effects or relationships.

Answer:

A) P(10 on three rolls) = 1/1728 = 0.0005787

B) P(10 in two of three rolls) = 11/1728 = 0.0063657

Step-by-step explanation:

Each die has 6 possible values, so a pair of dice have a total of 6*6=36 outcomes.

To find a sum of 10, the cases are:

(4,6), (5,5) and (6,4).

So to have a sum of 10 we have 3 cases among the 36 possible, therefore the probability is:

P(10) = 3/36 = 1/12

A)

If we want the sum of 10 in each of the three rolls, the probability is:

P(10 on three rolls) = P(10)^3 = (1/12)^3 = 1/1728 = 0.0005787

B)

If the sum is 10 in two of three rolls, in one roll we need the probability of the sum not being 10:

P(not 10) = 1 - P(10) = 1 - (1/12) = 11/12

So we have:

P(10 in two of three rolls) = P(10)^2 * P(not 10) = (1/12)^2 * (11/12)

P(10 in two of three rolls) = 11/1728 = 0.0063657

It is true that the indexed variables (members) of an array must be integers.

The indexed variables or members of an array must be integers. This is because arrays are data structures that store elements in a contiguous block of memory, and each element is accessed using an index. Indexing allows us to uniquely identify and retrieve specific elements within the array. In most programming languages, including C, C++, Java, and Python, array indices are integers and must be whole numbers (positive or negative) without any fractions or decimals. Attempting to use non-integer values as indices would result in a compilation error or unexpected behavior.

a) 27 business owners plan to provide a holiday gift to their employees.

b) Using a z-table, the p-value for z = -0.1583 is 0.4371 (rounded to four decimal places).

c) The smallest level of significance for which we could draw this conclusion would be equal to the calculated p-value, which is 0.4371 (rounded to four decimal places).

(a) In the survey of 60 business owners, 45% plan to provide a holiday gift to their employees. To find the number of business owners planning to give gifts, multiply the total number of business owners (60) by the percentage (0.45): 60 x 0.45 = 27 business owners plan to provide a holiday gift to their employees.

(b) To compute the p-value for a hypothesis test to determine if the proportion of business owners providing holiday gifts has decreased from last year, first, find the test statistic:

z = (p_sample - p_population) / sqrt((p_population * (1 - p_population)) / n)
z = (0.45 - 0.46) / sqrt((0.46 * (1 - 0.46)) / 60)
z = -0.01 / 0.0632 = -0.1583

Using a z-table, the p-value for z = -0.1583 is 0.4371 (rounded to four decimal places).

(c) Since the p-value (0.4371) is greater than the level of significance α=0.05, we fail to reject the null hypothesis. Thus, we cannot conclude that the proportion of business owners providing gifts has decreased based on the given level of significance.

The smallest level of significance for which we could draw this conclusion would be equal to the calculated p-value, which is 0.4371 (rounded to four decimal places).

It is about 1.657 times more probable to win a 6/48 lottery than a 6/52 lottery.

To find out how much more probable it is to win a 6/48 lottery than a 6/52 lottery, we need to compare their respective probabilities of winning.

The probability of winning a 6/48 lottery is given by the formula:

P(6/48) = C(6, 48) = 1/12271512

where C(6, 48) is the number of ways to choose 6 numbers out of 48.

Similarly, the probability of winning a 6/52 lottery is given by the formula:

P(6/52) = C(6, 52) = 1/20358520

where C(6, 52) is the number of ways to choose 6 numbers out of 52.

To find out how much more probable it is to win the 6/48 lottery than the 6/52 lottery, we can calculate their relative probabilities:

P(6/48) / P(6/52) = (1/12271512) / (1/20358520) ≈ 1.657

Therefore, it is about 1.657 times more probable to win a 6/48 lottery than a 6/52 lottery.
