Answer: a) 50% , and b) 50%.
Step-by-step explanation:
Since we have given that
P(A) = 41%
P(B) = 9%
P(AB) = 4%
P(O) = 46%
Since antigen A or antigen B are independent events.
So, P(A ∪ B) = P(A) + P(B)
Probability neither the A nor the B is given by
Hence, a) 50% , and b) 50%.
Answer:
A. 871.97 m
Step-by-step explanation:
Model this is a <u>right triangle</u>.
Use the <u>sine trigonometric ratio</u> to find the height of the weather balloon from the ground.
<u>Sine trigonometric ratio</u>
where:
is the angle
- O is the side opposite the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
- O = height
- H = 1601 m
Substitute the given values into the formula and solve for O:
