The surface area of a cylinder that the radius tripled and it height is brought down to half is 3890.46 inches²
<h3 /><h3>How to find the surface area of a cylinder?</h3>
Surface area of a cylinder = 2πr(r + h)
Therefore,
radius is tripled = 3(7) = 21 inches
height is shrunk half its size = 17 / 2 = 8.5 inches
Therefore,
surface area = 2 × 3.14 × 21 (21 + 8.5)
surface area = 131.88(29.5)
surface area = 3890.46 inches²

Answer:
36
Step-by-step explanation:
so 50% of 120 is just half of it. so that would be 60. Then 20% of 120 is 24 so subtract that from 60 and you get 36.
Answer:
the probability that an individual, selected at random, will score below the mean on any normally distributed characteristic is just about 0.5.
Step-by-step explanation:
This probability in normal distribution corresponds to z-score of 0. Using normal distribution tables.
P(z < 0) = 1 - P(z ≥ 0) = 1 - 0.5 = 0.5
Which is very logical, to score below the mean on a normal distribution, the probability is just less than 0.5.
