Answer:
The exponential function is Y = 200 [1.07]ˣ
Step-by-step explanation:
Let Y represent the expected population
Let P represent the current population
Let r represent the population growth rate
let x represent the number of years or nth year.
The compound interest expression can used to derive the exponential function can be represented as follows
Y = P [1 + (r ÷ 100)]ˣ
Y = 200 [ 1 + (7 ÷ 100)]ˣ
Y = 200 [ 1 + (0.07)]ˣ
Y = 200 [1.07]ˣ
It would be 46.34 percent.
Answer:
It can be done using poisson distribution.
λ = 30 calls/hr = 1.5 calls/3min
Now P(X=x)=e−λ.λxx!
So P(X=0)=e−1.5
Step-by-step explanation:
In the value 9,443.2 we can spot two 4's.
One resides in the hundreds column and the other resides in the tens column.

Step-by-step explanation:
If A and B are two different events then, P(A U B) = P(A) + P(B) - P(A ∩ B)
Explanation of the formula:
If you look at the Venn Diagram, if you add 2 areas : P(A) and P(B), P(A ∩ B) is overlapping. This is why you should remove P(A ∩ B).
However, in this case, we should find P(A ∩ B) and all the other values are given in the question. Hence, we implement them and find P(A ∩ B).
