identify each of the following as examples of nominal, ordinal, discrete, or continuous variables. (a) a poll of registered voters as to which candidate they support.
The candidate is an example of a nominal variable. Since candidates are identified through their names, the variable is qualitative in nature. Moreover, since names are all the voters have to go by, there is thus no inherent ordering in the candidates.
About nominal variableNominal variable is a variable with the lowest level of measurement scale and can only be used for qualitative classification or categorization. That is, these variables can only be measured in terms of whether the characteristics of an object can be distinguished from other characteristics, but we cannot measure or even rank these categories.
For example, we can say that the genders of the 2 people are different, one is female and the other is male. Here we can distinguish the characteristics of the two, but we cannot measure and say which is "more" or which is "less" from the quality represented by the variable.
We can only assign codes/labels to these two characteristics, for example the number 0 for women and the number 1 for men. The code/number label can be exchanged. The code there only serves as a differentiator between the two objects and does not indicate order or continuity. The number 1 does not indicate higher or better than 0.

Let X be a random variable with the following probability mass function:

Step-by-step explanation:
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.

Find the area of the triangle having the indicated angle and sides. (Round your answer to one decimal place.) C = 127o a = 2, b = 6
The area of the triangle is approximately 33.8 square units.
Heron's formula is applicable to all types of triangles. Heron's formula is used to compute the area of a triangle, and every sort of triangle in the world has an area.
So, if the three sides of a triangle are known, Heron's formula may be used to directly determine the area.
We can use the Law of Cosines to find the third side of the triangle, then use Heron's formula to find the area.
First, we find the third side, c:
c^2 = a^2 + b^2 - 2ab * cos(C)
c^2 = 2^2 + 6^2 - 2 * 2 * 6 * cos(127)
c = sqrt(40 - 24 * cos(127))
Next, we use Heron's formula to find the area of the triangle:
s = (a + b + c) / 2
area = sqrt(s * (s-a) * (s-b) * (s-c))
area = sqrt((7.82 + 3) * (7.82 - 2) * (7.82 - 6) * (3))
area = sqrt(45.82 * 5.82 * 1.82 * 3)
area = sqrt(1138.3916)
area = 33.75

Allow flyers using racial slurs is not one of the EDI initiatives discussed in the case.
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.

To determine the probability of a student working 19 hours or less, we need to find the cumulative frequency of students working 19 hours or less.
From the data, the cumulative frequency of students working 19 hours or less is 40 + 50 = 90. The total number of students is 200. Therefore, the probability of a student working 19 hours or less can be calculated as:
P(working 19 hours or less) = cumulative frequency of students working 19 hours or less / total number of students
P(working 19 hours or less) = 90 / 200
P(working 19 hours or less) = 0.45

The height above the ground of a passenger on a Ferris wheel t minutes after the ride begins is modeled by the differentiable function H, where H(t) is measured in meters. Which of the following is an interpretation of the statement H'(7.5) = 15.708?
The statement "H'(7.5) = 15.708" means that the rate of change of the height of the passenger on the Ferris wheel at 7.5 minutes after the ride begins is 15.708 meters per minute.
The statement H'(7.5) = 15.708 is an interpretation of the derivative of the function H at time 7.5 minutes. The derivative of a function represents the rate of change of the function, and it is calculated by taking the limit of the ratio of the change in the function to the change in its independent variable (in this case, time). H'(7.5) represents the rate of change of the height of the passenger at 7.5 minutes into the ride. The value of 15.708 means that the height of the passenger is increasing by 15.708 meters per minute at 7.5 minutes into the ride.
At 7.5 minutes into the ride, the passenger's height is changing at a rate of 15.708 meters per minute. This means that the passenger is moving upward at a speed of 15.708 meters per minute at this particular time. The derivative of a function at a specific point gives us the rate of change of the function at that point, and in this case, it gives us the speed at which the passenger's height is changing at 7.5 minutes into the ride.
