Since the whole set is composed of a total of 55 people, with 45 people being drinks of either coffer or tea, then the remaining people not included in the 45 would be the non-drinkers. So 55-45, meaning there are 10 people who drink neither tea nor coffee. To obtain the probability:
10/55 = 2/11 = 0.182
Therefore, the probability of a person being picked at random does not drink either coffee or tea is 0.182.
The height of the cylinder will be 5 units based on the information given.
<h3>How to calculate the height?</h3>
The cylinder has a volume of 45π cubic meters and the radius is 3 units.
The height will be calculated thus:
Volume of a cylinder = πr²h
45π = πr²h
45π = π(3²)h
45π = 9πh
h = 45π/9π
h = 5
Therefore, the height of the cylinder will be 5. units.

2L + 2W = perimeter
dividing both sides by 2
L + W = (perimeter / 2)
Length = (perimeter / 2) -Width
Width = (perimeter / 2) -Length
Answer:
(x+5)(x-3)
x = -5
x = 3
Step-by-step explanation:
find which 2 numbers when multiplied give -15 and when added give +2
they are +5 and -3
(x+5)(x-3)
x = -5
x = 3
