Answer:
ANSWER IS B
Step-by-step explanation:
use the following building blocks to assemble a proof that if m and n are integers, and mn is even, then m is even or n is even. not all blocks belong in the proof. before you start, you might want to write out such a proof on paper, and carefully consider whether a direct proof, a proof by contraposition or a proof by contradiction is the most appropriate.
Proof: If mn is even, then either m = 2k/n or n = 2k/m for an integer k, meaning either m or n must be even.
The following is a direct proof:
Assume m and n are integers.If mn is even, then n must be even or m must be even.We will show that if mn is even, then either m is even or n is even.Suppose mn is even.Then, there exists an integer k such that mn = 2k.This can be written as m = 2k/n or n = 2k/m.Since k is an integer, it follows that either m or n must be even.Thus, if mn is even, then either m is even or n is even.This completes the proof.The proof shows that if m and n are integers and mn is even, then either m must be even or n must be even. The proof starts by assuming that m and n are integers and that mn is even. It then proceeds to show that one of the factors, either m or n, must also be even.
The proof uses the definition of an even number, which is a number that is divisible by 2, to conclude that if mn is even, then there must be an integer k such that mn = 2k. From this equation, the proof derives the expressions m = 2k/n or n = 2k/m. Since k is an integer, it follows that either m or n must be even, since the result of dividing an integer by another integer is also an integer.
The proof concludes by stating that if mn is even, then either m must be even or n must be even, based on the logical reasoning provided in the proof.

x 0 1 2 3 4 5 Total
P(x) .04 .43 .29 .18 .05 .01 1.00
(a) Calculate the mean and standard deviation.
The mean of the data-set is given as follows:
E(X) = 1.8.
The standard deviation of the data-set is given as follows:
S(X) = 1.
How to obtain the mean and the standard deviation?The mean is given by the sum of all the outcomes multiplied by their respective probabilities, hence:
E(X) = 0 x 0.04 + 1 x 0.43 + 2 x 0.29 + 3 x 0.18 + 4 x 0.05 + 5 x 0.01
E(X) = 1.8.
The standard deviation is given by the square root of the sum of the difference squared between each outcome and the mean, multiplied by their respective probabilities, hence:
S(X) = sqrt[(0 - 1.8)² x 0.04 + (1 - 1.8)² x 0.43 + (2 - 1.8)² x 0.29 + (3 - 1.8)² x 0.18 + (4 - 1.8)² x 0.05 + (5 - 1.8)² x 0.01]

After Game 6 of the 2016 NBA Finals, Frank put down an even-money $100,000 bet on the Cavs to win Game 7 (and therefore, the championship). So, if the Cavs win, he wins $100,000, and if the Cavs lose, he loses $100,000. Suppose Frank has a logarithmic utility-of-wealth function: U(w) = ln(w), and his current wealth is $1,000,000 (one million dollars). Given that he accepted this bet, what can we determine about p, the probability with which Frank believes the Cavs will win Game 7? The goal of this problem is to figure this out. The subparts below will walk you through figuring this out
a) Write down an expression for Frank’s expected utility of wealth, as a function of p, if he takes the bet. [Remember to take into account his current wealth level as well as how winning or losing will change it.]
b) Frank’s other option is to reject the bet. What will his utility of wealth be if he rejects the bet?
c) If he accepts the bet, we know that the utility given for (a) must be larger than the utility given for (b). Write down and solve the inequality. You should be able to determine either a lower bound or upper bound for p, e.g. p ≤ 0.25 or p ≥.80.
d) Suppose Frank’s utility-of-wealth function was less curved, i.e. closer to a straight line. How would the bound from (c) change? Remember, the bound defines the range of possible probabilities p for him to accept the bet. Explain why it would be larger or smaller.
Frank's expected utility of wealth function if he takes the bet is U(w) = $1,000,000 + p(ln($100,000)) + (1-p)(ln($900,000)). If Frank accepts the bet, the probability p must be greater than or equal to 0.8.
a) Frank's expected utility of wealth if he takes the bet is U(w) = $1,000,000 + p(ln($100,000)) + (1-p)(ln($900,000))
b) If Frank rejects the bet, his utility of wealth will be U(w) = ln($1,000,000)
c) U(w) = $1,000,000 + p(ln($100,000)) + (1-p)(ln($900,000)) ≥ ln($1,000,000)
p(ln($100,000)) + (1-p)(ln($900,000)) ≥ ln($1,000,000) - $1,000,000
p(ln($100,000)) + (1-p)(ln($900,000) - ln($1,000,000)) ≥ -$1,000,000
p(ln($100,000) - ln($1,000,000)) + (1-p)(ln($900,000) - ln($1,000,000)) ≥ -$1,000,000
p(ln($100,000/$1,000,000)) + (1-p)(ln($900,000/$1,000,000)) ≥ -$1,000,000
p(ln(0.1)) + (1-p)(ln(0.9)) ≥ -$1,000,000
p(ln(0.1)) ≥ -$1,000,000 - (1-p)(ln(0.9))
p ≥ (-$1,000,000 - (1-p)(ln(0.9)))/(ln(0.1))
p ≥ -$1,000,000/(ln(0.1)) - (1-p)(ln(0.9))/ln(0.1)
p ≥ 0.8
d) If Frank's utility of wealth function was less curved, i.e. closer to a straight line, the bound from (c) would be larger. This is because, with a less curved utility of wealth function, Frank would be less risk-averse and therefore more likely to accept the bet.

The EDI initiatives discussed in the case include creating an inclusive community where all students thrive, establishing goals to retain underrepresented groups, and implementing a 12-week training program. To create an inclusive community, the school administration must first determine the current state of the campus environment. This can be done through surveys and focus groups, which allow the administration to identify what areas need improvement and how best to address them. Establishing goals to retain underrepresented groups involves setting specific goals for the recruitment and retaining of underrepresented groups, such as increasing the number of faculty or students from underrepresented groups.

Let X be a random variable with the following probability mass function:
f(x) =
x = 1: 0.2
x = 2: 0.3
x = 3: 0.5
This is indeed a probability mass function because the values of f(x) are all greater than or equal to 0, and the sum of the values of f(x) is equal to
To calculate the probability of x = 1, we can use the formula for probability mass functions: P(X = x) = f(x).
Therefore, the probability of x = 1 is 0.2.
To calculate the probability of x = 2, we can use the same formula: P(X = x) = f(x).
Therefore, the probability of x = 2 is 0.3.
