The personnel office at a large electronics firm regularly schedules job interviews and maintains records of the interviews. from the past records, they have found that the length of a first interview is normally distributed, with mean μ = 36 minutes and standard deviation σ = 9 minutes. (round your answers to four decimal places.)
a. what is the probability that a first interview will last 40 minutes or longer?
b. nine first interviews are usually scheduled per day. what is the probability that the average length of time for the nine interviews will be 40 minutes or longer?

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
