Answer:

The probability is $P(I | \ L ) =0.4$

Yes with the additional information that the person logs on everyday the probability increased from $P(I) = 0.3$ to $P(I | L ) = 0.4$

Step-by-step explanation:

From the question we are told that

The probability that the user is from outside the country is $P(O) = 0.7$

The probability that the user log on everyday is $P(L) = 0.6$

The probability that the user log on everyday and he/she is from inside the country is $P(L| I) = 0.80$

Generally using Bayes theorem the the probability that a person is from the country given that he logs on the website every day is mathematically represented as

$P(I | \ L ) = \frac{ P(L|I) * P(I)}{ P(L)}$

Here $P(I)$ is the probability that the person log on every day and it is mathematically evaluated as

$P(I) = 1 - P(O)$

$P(I) = 1 - 0.7$

$P(I) = 0.3$

$P(I | \ L ) = \frac{ 0,8 * 0.3}{ 0.6}$

$P(I | \ L ) =0.4$

For how many (not necessarily positive) integer values of n is the value 4000x(0.4)^n an integer?

Delicious77 [7]

The number of integer values of n for which the value 4000 × (0.4)ⁿ is an integer is; 9

<h3>How to find the integer values in algebra?</h3>

We are given the expression;

4000 × (0.4)ⁿ

This can also be expressed as;

4000 × (²/₅)ⁿ which can further be expressed in exponent form as;

(2⁵ × 5³) × (²/₅)ⁿ = 2⁽⁵ ⁺ ⁿ⁾ × 5⁽³ ⁻ ⁿ⁾

Since this expression is an integer, we need:

1) 5 + n ≥ 0 for which n ≥ -5

2) 3 - n ≥ 0 for which n ≤ 3

Taking the intersection gives;

-5 ≤ n ≤ 3

Thus;

Number of Integer Values = 3 - (-5) + 1 = 9
