3 pts An upper-level sociology class has 120 registered students: 34 seniors, 57
juniors, 22 sophomores, and 7 freshmen.
a. Imagine that you choose one random student from the classroom
(perhaps by using a random number table). What is the probability that
the student will be a junior?
b. What is the probability that the student will be a freshman?
C. If you are to select a disproportionate sample of size 20 from the
classroom, with equal numbers of students from each class level in the
sample, how many freshmen will there be in the sample?

what's that

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.
