Answer:
The value of given expression is .
Step-by-step explanation:
The given expression is
The trigonometric ratios are not defined for .
can be split into .
Using the addition formula
We know that, and
lies in third quadrant, by using reference angle properties,
Therefore the value of given expression is .
Answer:
Relative Risk = 1.5, so there is a positive association between the two groups so is likely to happen that Plant A has more chips than the labeled quantity as compared to Plant B
Step-by-step explanation:
The relative risk measuers the relationship between the risk group (Plant A) and the reference group (Plant B) in order to compare the probability of an event occurring in one group compared to the other.
It is calculated by dividing the probability of the event occurring for PLANT A divided by the probability of the same event occurring for PLANT B:
Probability for PLANT A = 18/100 = 0.18
Probability for PLANT B = 12/100 = 0.12
So RR= 0.18/0.16= 1.5
