To find the function f(x) when f'(x) = 3x + 7, we need to integrate the right-hand side of the equation.

Integrating both sides, we have:

∫f'(x) dx = ∫(3x + 7) dx

Using the power rule of integration, we can integrate each term separately:

∫f'(x) dx = ∫3x dx + ∫7 dx

Integrating each term, we get:

f(x) = (3/2)x^2 + 7x + C

where C is the constant of integration.

So, the function f(x) is given by:

Answer: f(x) = (3/2)x^2 + 7x + C, where C is a constant.

A hotel in the Algarve had to offer 1 week of vacation to one of its employees as an Easter gift in a random choice. It is known that 80 people work in this hotel unit, 41 of whom are Portuguese and 39 are foreign nationals. There are 14 Portuguese men and 23 foreign women. Using what you know about conditional probability, check the probability that the gift was offered to a Portuguese citizen, knowing that it was a woman.
