Answer: The required probability is 22.5%.
Step-by-step explanation:
Since we have given that
Probability of radio listeners live in Waterville = 0.75
Probability of radio listeners live in Newport = 0.25
Probability of radio station KTBC in Waterville = 0.20
Probability of radio station KTBC in Newport = 0.30
So, using "Multiplication rule of Probability":
Probability that the listener will be tuned in to station KTBC is given by
Hence, the required probability is 22.5%.
Answer: approximately 311 feet
I rounded to the nearest whole number since the other given values are whole numbers. The more accurate value is roughly 310.825323188148 feet.
=========================================================
Explanation:
Refer to the diagram below. When using the 47 degree as the reference angle, we know that,
We can say:
sin(angle) = opposite/hypotenuse
sin(47) = x/425
425*sin(47) = x
x = 425*sin(47)
x = 310.825323188148
x = 311
The kite is approximately 311 feet off the ground.
