Answer:
70.3km
Step-by-step explanation:
When the bearings are visualized and the points connected as a triangle, The angle x would be the difference of the both bearings from x
i.e 117-41 = 76
Using cosine rule,
YZ²= 43² + 67² - 2 x 43 x 67
cos76
YZ= √4944
= 70.3
Answer:
R is not collinear.
S is collinear.
Step-by-step explanation:
The equation of the graph is given by y =x +2 ........ (1).
Now, the points P and Q having coordinates (5,7) and (-1,1) respectively lie on the graph of the equation (1) because those points satisfy the equation.
Now, if we consider another point R having coordinates (1,-1), then it does not lie on the graph of equation (1) as it does not satisfy the equation.{If you put x=1, then y will be 3 but not -1}
Therefore, P, Q, R are not collinear. (Answer)
Again if we consider the point S(-3,-1), it satisfies equation (1).{If you put x=-3 in the equation (1), y will be -1}.
Therefore, P, Q, and S lie on the same straight line. and they are collinear. (Answer)

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
