omers to find one who buys apples? Which simulation design has an appropriate device and a correct trial for this problem?
A) Roll a fair die where 1-2 are buying apples and 3-6 are not buying apples. Roll the die until you get a 1 or 2. Record the number of rolls it took you.
B) Using a random digits table select one digit numbers where 0-2 is a customer who buys apples and 3-9 is a customer who does not. Keep selecting one digit numbers until you get a 0-2. Record the number of digits selected.
C) Using a random digits table select one digit numbers where 0-1 is a customer who buys apples and 2-9 is a customer who does not. Keep selecting one digit numbers until you get a 0 or 1. Record the number of digits selected.
D) Spin a spinner that is split up into 5 sections, where 2 sections are a success of buying apples and the other three sections are not buying apples. Keep spinning until you get someone that buys apples. Record the number of spins it took you.
C) Using a random digits table select one digit numbers where 0-1 is a customer who buys apples and 2-9 is a customer who does not. Keep selecting one digit numbers until you get a 0 or 1. Record the number of digits selected.
the right answer is 7 and 4 because the angles are between the two lines that are not the transversal and are on diagonal opposite sides of the transversal.
To start off, Chang has already saved $45. $125 - $45 = $80. Therefore, he owes $80. $80 ÷ 7 = 11.4285714286, so he needs to work 12 full hours to pay for his trip.
