Answer:
From the first generation = 2 ancestors.
From the second generation = 4 ancestors or (2)^2 ancestors.
From the third generation = 8 ancestors or (2)^3 ancestors.
We can infer from the given data, each consecutive generation possesses twice the number of members.
The sum will be:
2 + 4 + 8 + 16 + ... + (2)^39
To evaluate the amount of ancestors, let's employ the formula for the summation of a geometric sequence.
(Geometric sequence shows the sequence of numbers that varies by a specific factor. This factor is specifically known as a ratio).
Formula for Geometric sequence:
S = (a1) × 1 - (r)^n
--------------------------
1 - r
Take:
S -> sum
a1 -> first member of a sequence
r -> ratio
n -> number of elements
In this question, our:
a1 = 2; r = 2; and n = 39
S = (2) × 1 - (2)^39
-------------------------
1 - 2
S = 1,099,511,627,777
Answer:
Extrapolation
Explanation:
In statistics, extrapolation refers to making an estimate on the future value or behavior of a certain variable based on the current available data. However, extrapolation is subject to a great degree of uncertainty, as it's impossible to account for all the possible variables in the present, and it's next to impossible to know what new variables will affect our calculations in the future. Weather forecasts in particular is an area where errors in the forecasts are very common. This is because making completely accurate predictions is still not possible, mostly because the weather can be affected by countless variables that can't be all measured or accounted for when making a forecast. However, while wrong forecasts can make people angry, forecasters and civil defense authorities have to err on the side of caution. It is better to deal with some people being angry at an unnecessary evacuation, than having people risking their lives in an area affected by a hurricane.
