Answer:
3:1
Step-by-step explanation:
area is 2D while the perimeter is a length which is 1D. you can also about this in how the area is units squared while the perimeter is just units. so we need the square roote of 9 and 1, sqrt(9) = 3, sqrt(1) = 1. so the ratio of the perimeter is 3:1
Answer:
The answer is 243 I believe
Step-by-step explanation:
Multiply 27 times 6, once you get the product of that, multimply that by 3. Once you have done all of that multiply that by 1/2 or 0.5
Answer: 0.1840
Step-by-step explanation:
The binomial probability formula :-
, here n is the number total of trials , p is the probability of getting success in each trial and P(x) is the probability of getting success in x trial.
Given : The probability of the community favored building a police substation in their neighborhood = 0.64
If 14 citizens are chosen, then the probability that exactly 8 of them favor the building of the police substation will be :-

Hence, the probability that exactly 8 of them favor the building of the police substation = 0.1840
Consider the bottom most rectangle.
Its length = 5 - 2 = 3 units
Its width = 3 - 1 = 2 units
So, its area = 3(2) = 6 square units.
Consider the middle rectangle.
Its length = 2 - 1 = 1 unit
Its width = 4 - 2 = 2 units
So, its area = 1(2) = 2 square units.
Finally, consider the top rectangle.
Its length = 6 - 1 = 5 units
Its width = 6 - 4 = 2 units
Its area = 5(2) = 10 square units.
Hence, total area = 6 + 2 + 10 = 18 square units. Correct option is C.
