$a_{n} = +(n-1)d$

We are given the first term and the common difference.

So,

$a_{1}=-10 \\ \\ d=5$

Using these values in the given equation, we get:

$a_{n} =-10+(n-1)*5 \\ \\ 
 a_{n} = -10 + 5n - 5 \\ \\ 
 a_{n} = 5n -15$

So, option C gives the correct answer.

Answer:

P (X | CI) = 0.7313

Step-by-step explanation:

X = event of getting a job

CI = Campus interview

P (X | CI) = p ( CI ∩ X) / P ( CI ) = P( CI | X)P(X) / P( CI | X)P(X) + P( CI | X')P(X')

P (X | CI) = 0.93 * 0.17 / 0.93 * 0.17 + 0.07 * (1 - 0.17)

P (X | CI) = 0.93 * 0.17 / 0.93 * 0.17 + 0.07 * 0.83
