There are n applicants for the director of computing. The applicants are interviewed independently by each member of the three-p
Delvig [45]

Answer:

for  n =  3

       Z(3) = 0.26  

for  n =  10

       Z(3) = 0.028

Step-by-step explanation:

from the question we are that

  The  number of applicant is n

  The  number of  people on the committee is N = 3

 

Generally given that the applicant ranking is random the probability of a candidate being accepted is mathematically represented as

       Z(n) =  N  *  \frac{1}{n} *  \frac{1}{n}  *  \frac{n-1}{n}  + \frac{1}{n} *  \frac{1}{n} * \frac{1}{n}

Now  for  n =  3

       Z(3) =  3  *  \frac{1}{3} *  \frac{1}{3}  *  \frac{3-1}{3}  + \frac{1}{3} *  \frac{1}{3} * \frac{1}{3}      

         Z(3) = 0.26            

Now  for  n =  10

       Z(3) =  3  *  \frac{1}{10} *  \frac{1}{10}  *  \frac{10-1}{10}  + \frac{1}{10} *  \frac{1}{10} * \frac{1}{10}      

         Z(3) = 0.028

Henri puts aside $10 cash every month in a shoebox. He also makes a one-time deposit of $1,500 in a savings
Anestetic [448]

Answer:

T(t) = f(t) + g(t)

Step-by-step explanation:

The function which represents the total amount of money Henri will have in t years is the function obtained using an addition operation in the two defied functions, f(t) and g(t) ; total amount saved in shoe box plus the total compounded amount in savings account

Total amount of money in t years, T(t) ;

T(t) = 120t + 1,500(1.09)^t

f(t) = 120t

g(t) = 1,500(1.09)^t

Hence,

T(t) = f(t) + g(t)
