For this case we have a function of the form $y = f (x)$ where:

$f (x) = - 2x-1$

We must find the value of the function when $x = -7$ . So:

$f (-7) = - 2 (-7) -1$

By definition we have to:

$- * - = +\\f (-7) = 14-1 = 13$

Thus, the value of the function is $y = 13$

Answer:

$y = f (-7) = 13$

Suppose that 8% of the students in your school are Swedish. If you stop students at random in the hall way and ask whether they'

const2013 [10]

Given that 8% of the students are Swedish, this means that 100 - 8 = 92% are not Swedish.

Let S represent the event that a student is Swedish and N represent the event that a student is not a Swedish.

Then, the probability that a student chosen at random is a Swedish, P(S), = 8% = 0.08
The probability that a student chosen at random is not a Swedish, P(N), = 92% = 0.92

That the first Swedish person found was on the third trial means that the first and second trial produced a non-Swedish.

Therefore, the required probability = 0.92 x 0.92 x 0.08 = 0.068 to three decimal places.
