B. The probability of selecting an undergraduate and registered online student is 0.604

Step-by-step explanation:

Given

-----------------------Registered Online Registered In Person

Undergraduate --211 -- 347

Graduate --- 329 --- 581

Required

Probability that a randomly selected student is either an

undergraduate or registered online

First all data need to be properly represented..

Let U, G, Ro and Rp represented Undergraduate, Graduate, Registered online and Registered in person respectively

The data on first row represent data for undergraduate;.

Hence U = 211 + 347

U = 558

The data on the second row represent data for graduate;.

Hence G = 329 + 581

G = 910

The data on first column represent data for registered online

Hence Ro = 211 + 329

Ro = 540

The data on the second column represent data for registered in person;.

Hence Rp = 347 + 581

Rp = 928

Total student that participated in the survey = 211 + 347 + 329 + 581

Total = 1468

Probability that a randomly selected student is either an undergraduate or registered online is represented as P(U or Ro)

From probability formula;

P(U or Ro) is calculated as follows

P(U or Ro) = P(U) + P(Ro) - P(U and Ro)

Where P(U) = probability of selecting an undergraduate student

P(U) = number of undergraduates divided by total

$P(U) = \frac{558}{1468}$

P(Ro) = probability of selecting a registered online student

P(Ro) = number of registered online student divided by total

$P(Ro) = \frac{540}{1468}$

P(U and Ro) = probability of selecting an undergraduate and registered online student

P(U and Ro) = number of undergraduates and registered online students divided by total

From the table above, number of undergraduates and registered online = 211

$P(U and Ro) = \frac{211}{1468}$

By substituting each of these expressions, we have

$P(U or Ro) = \frac{558}{1468}+ \frac{540}{1468} - \frac{211}{1468}$

$P(U or Ro) = \frac{558 + 540 - 211}{1468}$

$P(U or Ro) = \frac{887}{1468}$

P(U or Ro) = 0.604223

P(U or Ro) = 0.604 (Approximated).

Hence, probability of selecting an undergraduate and registered online student is 0.604

The two figure shown above are congruent. identify the corresponding sides and angles.

Answer from: Quest

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

In a study of the relationship between socio-economic class and unethical behavior, 129 university of california undergraduates at berkeley were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. they were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. after completing some unrelated tasks, participants reported the number of candies they had taken. it was found that those who were identiď¬ed as upper-class took more candy than others. in this study, identify: (a) the cases, (b) the variables and their types, (c) the main research question, (d) identify the population of interest and the sample in this study, and (e) comment on whether or not the results of the study can be generalized to the population, and if the ď¬ndings of the study can be used to establish causal relationships.
