To find the average change in your account balance after each trip, you need to divide the total withdrawal amount by the number of trips. So, in this case, you would divide $260 by 5 trips.
Average Change in Account Balance = Total Withdrawal Amount / Number of Trips
Average Change in Account Balance = $260 / 5
Average Change in Account Balance = $52
Therefore, the average change in your account balance after each trip is $52.
To find the depth below the water's surface that the submarine will reach in 4 minutes, you need to multiply the rate of descent (60 ft./min) by the time (4 min).
Depth Below Water's Surface = Rate of Descent * Time
Depth Below Water's Surface = 60 ft./min * 4 min
Depth Below Water's Surface = 240 ft.
Therefore, the submarine will reach a depth of 240 ft below the water's surface after 4 minutes.
To determine how many points each incorrect answer is worth in the trivia game, you need to divide the total score (-75 points) by the number of incorrect answers (3 answers).
Points per Incorrect Answer = Total Score / Number of Incorrect Answers
Points per Incorrect Answer = -75 / 3
Points per Incorrect Answer = -25
Therefore, each incorrect answer is worth -25 points.
