The first thing you should do in this case is to take out the area of the patio and the area covered by each brick.
Patio area = (15) * (20) = 300 ft ^ 2
Area brick = (1) * (1) = 1ft ^ 2
Then, to get the number of bricks we have:
n = (Patio area) / (Area brick)
n = (300) / (1)
n = 300
Therefore, 300 bricks are needed. This means that the total cost is
total cost = (2) * (300) = 600 $
answer
Sam will spend if he buys exactly enough tiles to cover his patio $ 600

Answer:
b). posterior probabilities.
Step-by-step explanation:
Posterior Probabilities are described as the updated probabilities which are estimated employing the theorem proposed by Baye. According to his theorem, an association is developed between probability and the newly received information. <u>When the previously existing probabilities are amalgamated with this updated information, it gives the existing probabilities' value a correction, update, or revision namely 'posterior probabilities</u>.' Thus, it is the probability that asserts the truth of a hypothesis and hence, <u>option b</u> is the correct answer.
Answer: The height of the tree is 12.57 ft.
Step-by-step explanation:
The height of a thing is proportional to the its shadow.
Let H = Height and S = length of shadow
Then by equation direct proportion , 
(i)
Given : A tree that casts a 22 ft shadow at the same time a 4 ft postpost casts a shadow which is 7-ft long.
Put 
in (i), we get
Hence, the height of the tree is 12.57 ft.
