A line passes through the point (2, 3) and has an undefined slope, what is the equation of the line? A) y = 2 B) y = 3 C) x = 2

Harman [31]

"Undefined" slope means the line is vertical, of the form x = constant. The constant is the x-value of the point the line goes through.

C) x = 2

A supervisor has to estimate the cost to unload a shipment. The cost of labour is $33 per hour, per worker.

Agata [3.3K]

The answer is D cause 1/4 of 33$ is 8.25 so you do 33+33+33 which is 99 then you multiply that by 6 which is 594 then you multiply 8.25 by 3 to account for all the workers then add that to 594 and then you get your answer which is 618.75

Two part-time instructors are hired by the Department of Statistics and each is assigned at random to teach a single course in p

scZoUnD [109]

Answer:

The probability that they will teach different courses is $\frac{2}{3}$ .

Step-by-step explanation:

Sample space is a set of all possible outcomes of an experiment.

In this case we will write the sample space in the form (x, y).

Here x represents the course taught by the first part-time instructor and y represents the course taught by the second part-time instructor.

Denote every course by their first letter.

The sample space is as follows:

S = {(P, P), (P, I), (P, S), (I, P), (I, I), (I, S), (S, P), (S, I) and (S, S)}

The outcomes where the the instructors will teach different courses are:

s = {(P, I), (P, S), (I, P),(I, S), (S, P) and (S, I)}

The probability of an events E is the ratio of the number of favorable outcomes to the total number of outcomes.

$P(E)=\frac{n(E)}{N}$

Compute the probability that they will teach different courses as follows:

$P(\text{Different courses})=\frac{n(s)}{n(S)}=\frac{6}{9}=\frac{2}{3}$

Thus, the probability that they will teach different courses is $\frac{2}{3}$ .
