Recall that the reciprocal of the csc function is the sin function, which is an odd function. The angle -pi/6 has its terminal side in Quadrant 4, for which the opposite side is negative, important in determining the sign of csc(-pi/6).
sin(-pi/6) = - sin(pi/6) = -1/2.
Thus, csc(-pi/6) = -1 / (-1/2), or +2 (answer)
Answer:
Simple random sampling
Observational study
Step-by-step explanation:
Since in the given situation it is mentioned that department wants to test the computer virus and have to run the virus on the random selected computers so here the simple random sampling would be done and based on the simple random sampling the observational study would be done
Therefore the above represent the answer
Answer: the team scored 18 (1 - point shot) and 35 (2 - point shots).
Step-by-step explanation:
Let x represent the the number of
1- point shot that the team made.
Let y represent the the number of
2- points shot that the team made.
The team made 53 successful shots. They were a combination of 1- and 2- point shots. This means that
x + y = 53
The team scored 88 points in all. This means that
x + 2y = 88- - - - - - - - - - - -1
Substituting x = 53 - y into equation 1, it becomes
53 - y + 2y = 88
- y + 2y = 88 - 53
y = 35
x = 53 - y = 53 - 35
x = 18
