Answer:
The answer is 600 minutes (10 hours)
Step-by-step explanation:
20 minutes = 1 student.
30 students x 20 = 600 minutes
600mins / 60 (because an hour has 60 mins) = 10 hours.

The probability that the selected manager has no college background and only have a fair look is 0.05625
Table is missing. Attached below.
Given,
We have to find the probability that the selected manager has no college background and only have a fair look;
From the table;
The total number of managers surveyed = 160
Number of managers surveyed are fair = 9
Probability;-
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
Here,
The probability = Number of managers surveyed are fair / The total number of managers surveyed
The probability = 9/160 = 0.05625
That is,
The probability that the selected manager has no college background and only have a fair look is 0.05625

the easiest way I find a midpoint of two points is the midpoint theorem, here it is:

For x and y plug in the two coordinates given, (4,-4) & (0,8)
so once you plug the numbers into the equation you would get:
(2,2)
Y+ 2+ 6(y+6)
= Y+ 2+ 6y+ 36 (distributive property)
= Y+ 6y+ (2+ 36) (combine like terms)
= Y+ 6y+ 38
The final answer is Y+ 6y+ 38~
