According to the question the correct option is c. Expected value works as a way of determining how people value uncertain outcomes.
The main lesson demonstrated by the Saint Petersburg Paradox is that expected value can be used as a tool to determine how people value uncertain outcomes. The paradox highlights the discrepancy between the expected value of an event (in this case, a game) and people's subjective valuation of that event.
Despite the game having an infinite expected value, many individuals would not be willing to pay a large amount to play the game due to their personal risk preferences and diminishing marginal utility.
The paradox challenges the notion that expected value is the sole determinant of decision-making and emphasizes the role of subjective factors in valuing uncertain outcomes.

This large cube sculpture at the University of Michigan is made of steel. Even though it is extremely heavy, students can walk by and spin the cube very easily. Each side of the cube measures 15 feet across.
If this cube was a perfect cube and filled with sand, how much sand would be needed to completely fill it?
We would need 337,500 pounds of sand to completely fill the cube with sides measuring 15 feet across if it were a perfect cube.
The volume of a cube is calculated by taking the length of one side and raising it to the power of 3. In this case, the cube has sides that measure 15 feet each, so the volume can be calculated as:
Volume of cube = (Length of one side)^3 = (15 feet)^3 = 3,375 cubic feet
To fill the cube with sand, we would need to add enough sand to completely fill this volume. The weight of the sand we need can be calculated using its density. The density of sand varies depending on the type of sand, but a common density for dry sand is around 100 pounds per cubic foot.
Therefore, the weight of sand needed to fill the cube would be:
Weight of sand = (Volume of cube) x (Density of sand) = 3,375 cubic feet x 100 pounds per cubic foot = 337,500 pounds
It is worth noting that the real cube sculpture at the University of Michigan is not a perfect cube and is not filled with sand.

give an estimated simple linear regression equation of = 46.2 589.2x with a coefficient of determination r2 of 0.7523, interpret the coefficient of determination for this equation.
The estimated simple linear regression equation is y = 46.2 + 589.2x, with a coefficient of determination (r^2) of 0.7523.
The coefficient of determination (r^2) measures the proportion of the total variation in the dependent variable (y) that can be explained by the independent variable (x) in a linear regression model. In this case, the coefficient of determination is 0.7523, indicating that approximately 75.23% of the variation in the dependent variable (y) can be explained by the independent variable (x) using the given regression equation. This means that the linear relationship between x and y accounts for 75.23% of the variability observed in y. The remaining 24.77% of the variation is attributed to other factors not included in the model. A higher value of r^2 indicates a stronger relationship between the variables.

Lighthouse B is 9 miles west of lighthouse a a boat leaves a and sales 6 miles. At this time it is lighted from B. If the bearing of the boat from B is North 64° east how far from be is the boat?
Answer:
12.61 miles
Step-by-step explanation:
The distance of lighthouse B from lighthouse A, the distance from lighthouse A to the boat and the distance of lighthouse B from the boat all form a triangle. Since lighthouse B is west of lighthouse A, and at a distance of 9 miles form lighthouse A, light house A is at a bearing of North 90° East of lighthouse B. The distance from lighthouse A to the boat is 6 miles, and the bearing of the boat from lighthouse B is North 64° East.
So, the angle between the distance from lighthouse B to the boat and lighthouse B to lighthouse A is 90° - 64° = 26°
Since we have two sides and an angle, we use the sine rule
a/sinA = b/sinB where a = 6, A = 26°, b = 9, B = unknown
So, sinB = bsinA/a
= 9sin26/6
= 3(0.4384)/2
= 1.3151/2
= 0.6576
B = sin⁻¹(0.6576)
= 41.11°
≅ 41.1°
We now find the third angle in the triangle, C(the angle facing the distance from lighthouse B to the boat) from
26° + 41.1° + C = 180° (sum of angles in a triangle)
67.1° + C = 180°
C = 180° - 67.1° = 112.9°
Using the sine rule again to find the third side, c(the distance from lighthouse B to the boat), we have
a/sinA = c/sinC
c = asinC/sinA
= 6sin112.9°/sin26°
= 6(0.9212)/0.4384
= 5.5271/0.4384
= 12.61 miles
USA Today reported that the population mean life span of people who live in Hawaii is 77 years. A random sample of 20 obituary notices gave a sample mean life span of x= 71.4 years and a sample standard deviation s = 20.65 years. Assuming that the life span of people in Hawaii is normally distributed, does this indicate that the population mean life span is less than 77 years? Use a 5% level of significance. a.) What is a? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two tailed test?
α = ____
H_0: µ = _____
H_1: µ = _____
The test is a _______ test.
Yes, there is evidence to suggest that the population mean life span in Hawaii is less than 77 years.
How to find that is there statistical evidence that the mean life span in Hawaii is less than 77 years?The hypothesis test in question aims to determine if there is sufficient evidence to support the claim that the population mean life span in Hawaii is less than 77 years.
The null hypothesis (H₀) assumes that the mean life span is equal to 77 years, while the alternative hypothesis (H₁) suggests that the mean life span is less than 77 years.
To conduct the hypothesis test, a significance level (α) of 5% is chosen, which corresponds to a 95% confidence level.
Since the question asks whether the population mean is less than 77 years, this is a left-tailed test.
Using the given sample information, the test statistic can be calculated using the formula:
t = (x - µ) / (s / √n), where x is the sample mean (71.4), µ is the population mean (77), s is the sample standard deviation (20.65), and n is the sample size (20).
By plugging in the values, the test statistic is calculated to be t = (71.4 - 77) / (20.65 / √20) ≈ -1.64.
To determine whether the test statistic falls in the critical region, the critical value for a left-tailed test at α = 0.05 is obtained from the t-distribution table or calculator.
With 19 degrees of freedom, the critical value is approximately -1.73.
Since the test statistic (-1.64) is not less than the critical value (-1.73), we fail to reject the null hypothesis.
This means that there is insufficient evidence to conclude that the population mean life span in Hawaii is less than 77 years at a 5% level of significance.

Compute the following by using ancient Egyptian multiplication: (a) 74 X 64 (b) 129 X 413 (c) 58 X 692 (d) 4968 X 1234
Using Ancient Egyptian multiplication, the values are obtained as: (a) 74 × 64 = 2724: (b) 129 × 413 = 35405: (c) 58 × 692 = 30456: (d) 4968 × 1234 = 6148172.
Ancient Egyptian multiplication, also known as Egyptian multiplication or the method of multiplication through doubling and halving, is a method used by ancient Egyptians to multiply two numbers.
It involves breaking down one of the numbers into a sum of powers of two and then adding the corresponding multiples of the other number. Here's how you can compute the given multiplications using ancient Egyptian multiplication:
(a) 74 × 64:
We start with the number 1 and keep doubling it until we reach a number greater than or equal to 74. We then create a column for each power of 2 that was used, and write the corresponding multiple of 64 in each column. Finally, we add the numbers in the columns corresponding to the powers of 2 that make up 74.
1 × 64 = 64
2 × 64 = 128
4 × 64 = 256
8 × 64 = 512
16 × 64 = 1024
32 × 64 = 2048
Adding the numbers corresponding to powers of 2 that make up 74:
64 + 0 + 0 + 512 + 0 + 2048 = 2724
Therefore, 74 × 64 = 2724.
(b) 129 × 413:
1 × 413 = 413
2 × 413 = 826
4 × 413 = 1652
8 × 413 = 3304
16 × 413 = 6608
32 × 413 = 13216
64 × 413 = 26432
Adding the numbers corresponding to powers of 2 that make up 129:
413 + 0 + 1652 + 0 + 6608 + 0 + 26432 = 35405
Therefore, 129 × 413 = 35405.
(c) 58 × 692:
1 × 692 = 692
2 × 692 = 1384
4 × 692 = 2768
8 × 692 = 5536
16 × 692 = 11072
32 × 692 = 22144
Adding the numbers corresponding to powers of 2 that make up 58:
692 + 1384 + 0 + 5536 + 0 + 22144 = 30456
Therefore, 58 × 692 = 30456.
(d) 4968 × 1234:
1 × 1234 = 1234
2 × 1234 = 2468
4 × 1234 = 4936
8 × 1234 = 9868
16 × 1234 = 19668
32 × 1234 = 39468
64 × 1234 = 78936
128 × 1234 = 157872
256 × 1234 = 315744
512 × 1234 = 631488
1024 × 1234 = 1262976
Adding the numbers corresponding to powers of 2 that make up 4968:
1234 + 2468 + 4936 + 0 + 19668 + 39468 + 78936 + 157872 + 315744 + 0 + 1262976 = 6148172
Therefore, 4968 × 1234 = 6148172.
Using the ancient Egyptian multiplication method, we have computed the products for the given multiplications.

Answer:
a. ∆ABC ~ ∆A'B'C'
b. Enlargement
c. Scale factor = 4
Step-by-step explanation:
a. <A corresponds to <A'
<B corresponds to <B'
<C corresponds to <C',
Therefore, the similarity statement would be: ∆ABC ~ ∆A'B'C'
b. The image of the dilation is an enlargement of the original figure because the side lengths of ∆A'B'C are larger than the corresponding side lengths of ∆ABC.
c. Scale factor = the ratio of the corresponding sides
Thus:
Scale factor = A'B'/AB = B'C'/BC = A'C'/AC
Scale factor = 24/6 = 48/12 = 60/15 = 4
Scale factor = 4
A particular type of mouse's weights are normally distributed, with a mean of 409 grams and a standard deviation of 24 grams. If you pick one mouse at random, find the following: (round all probabilities to four decimal places) a) What is the probability that the mouse weighs less than 332 grams? b) What is the probability that the mouse weighs more than 480 grams? c) What is the probability that the mouse weighs between 332 and 480 grams? d) Is it unlikely that a randomly chosen mouse would weigh less than 332 grams? No, the likelihood exceeds 5% Yes, the likelihood is less than 50% Yes, the likelihood is less than 5% No, the likelihood exceeds 50% e) What is the cutoff for the heaviest 6% of this type of mouse? grams (round to the nearest whole gram).
a) To find the probability that the mouse weighs less than 332 grams is calculated using the z-score formula which is: z= (x-μ)/σ where, x=332μ=409σ=24z= (332−409)/24z=−3.21
Hence, P (x < 332) = P (z < -3.21)
The probability that the mouse weighs less than 332 grams is approximately equal to 0.0007. Therefore, the answer is 0.0007 (rounded to four decimal places).
b) To find the probability that the mouse weighs more than 480 grams is calculated using the z-score formula which is: z= (x-μ)/σwhere,x=480μ=409σ=24z= (480−409)/24z=2.96
Hence, P (x > 480) = P (z > 2.96)
The probability that the mouse weighs more than 480 grams is approximately equal to 0.0015. Therefore, the answer is 0.0015 (rounded to four decimal places).
c) To find the probability that the mouse weighs between 332 and 480 grams is calculated using the z-score formula which is: P (332 < x < 480) = P (-3.21 < z < 2.96)
Hence, the probability that the mouse weighs between 332 and 480 grams is approximately equal to 0.9980. Therefore, the answer is 0.9980 (rounded to four decimal places).
d) The probability of a randomly chosen mouse weighing less than 332 grams is found to be P (x < 332) = 0.0007 which is less than 5%. Therefore, it is unlikely that a randomly chosen mouse would weigh less than 332 grams. Hence, the answer is "Yes, the likelihood is less than 5%".
e) To find the cutoff for the heaviest 6% of this type of mouse can be done by using the Z-table, that gives the z-score for any given probability. For the heaviest 6%, we need to find the z-score corresponding to a probability of 0.94 (100% - 6%). Hence, the Z-score for 0.94 probability is 1.55. Cutoff weight = μ + Z-score * σ= 409 + 1.55 * 24 = 447.2 ≈ 447 (rounded to the nearest whole gram). Therefore, the answer is 447 (rounded to the nearest whole gram).
