Answers:
The next two terms are 67.5 and 101.25 in that order.
===========================================
Explanation:
Divide the second term over the first to get 30/20 = 1.5
Divide the third term over the second term to get 45/30 = 1.5
The common ratio is 1.5, which means we multiply 1.5 by each term to get the next term
-------
fourth term = 1.5*(third term) = 1.5*45 = 67.5
fifth term = 1.5*(fourth term) = 1.5*67.5 = 101.25
-------
As a shortcut you can plug n = 4 and n = 5 into the function t(n) = 20*(1.5)^(n-1) to get the fourth and fifth terms respectively.
7 tiles with plants and 2 tiles with animals...total of 9 tiles
she flips a plant tile, and does not replace it.
probability that 2nd tile is a plant = 6/8 = 0.75 = 75%
Answer:
Step-by-step explanation:
The conditional probability P(W|X) means "Probability of W happening GIVEN THAT X has happened".
We want to find P(Trig|Male). This would mean, we want people who are male...then we look, how many of them took Trig.
Looking at the table, row and column of Trig & Male is "8".
Hence, Probability would be 8/48 [48 is the total number of people, given in right bottom most part of the table]
8/48 = 1/6
Correct answer is 2nd option, 1/6
Answer:
14 square meters
Step-by-step explanation:
The formula for the area of a parallelogram of length L and height H is
A = L * H.
Here, the area is A = (2 meters) * (7 meters) = 14 square meters.
This answer hinged upon my understanding of this situation, and could be incorrect because I'm not taking into account the "triangle" mentioned here. When at all possible you should share any diagrams given in the problem statement, or at least describe them accurately in words.
