Answer:2.9235
Step-by-step explanation:
Since 20 people are administered the medicine and;
11% of the 20 people suffer severe i.e 11% of 20 = 2.2 people
20% of them suffer moderate i.e
20% of 20 = 4 people and;
69% of the 20 people suffer minor side i.e
69% of 20 = 13.8 people
Therefore the probability 2, 4, and 14 people will suffer severe, moderate, or minor side effects, respectively will be;
2/2.2 + 4/4 + 14/13.8 (i.e possible outcome/total outcome)
This will give us 2.9235
Answer:
b = 25.03,
c = 32.67 to the nearest hundredth.
Step-by-step explanation:
To find b and c you can use the trigonometry of a right angled triangle.
tan 50 = b / 21
b = 21 tan 50
b = 25.03
cos 50 = 21 / c
c = 21 / cos 50
= 32.67
49% because there's 98% that the test is right BUT you only have 0.5% chance to actually have it, so 98×0.5=49
