Answer:
28
Step-by-step explanation:
i am not completely sure, but if you flip each coin 28 times then you would have flipped them both 56 times. There is a 50% that it will land on heads so you would divide 56 by 2 and that would be 28. sorry if it's wrong.
Answer:
Can you get a picture please or more detail...
To answer this question, an assumption must be made, that Eva spends 8 hours a day working. If this is the case, then Eva will complete jobs w, x, and v on day one, for a total of six hours. Since the next job (y) requires 4 hours, she will spend two hours working that day, leaving 2 more hours to go on that job. The next day she will spend 2 hours finishing job y, completing it, and finish the longest job z (hours) that day. This means she had 4 jobs on day one, and 2 jobs on day 2 for and average of 3 jobs per day.
This answer assumes an 8 hour work day, and that Eva can start a job she cannot finish that day.
