Your computer server recently crashed and you need to make changes to a large manual. the manual contains approximately 16,000 words. a clerk types 4,160 words in one hour and 20 minutes. the salary and benefits for the clerk cost the firm approximately $17.65/hour. how much will recreating the manual cost the firm? $68.28 $308.01 $90.51 $5,420

Third option is correct.

Step-by-step explanation:

Since we have given that

Number of words the manual contains= 16000

Number of words typed by a clerk in one hour and 20 minutes = 4160

According to question we will use "Unitary method":

Number of hours is need to type 4160 words is given by

Number of hours is needed to type 1 word is given by

Number of hours is needed to type 16000 words is given by

Now, the clerk cost per hour = $17.65

So, the manual cost that will take to recreate by the firm is given by

Hence, Third option is correct.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
