A scuba diver wants to descend at an average rate of at least 7 feet per minute for 5 minutes. The table shows how many feet the scuba diver descends in the first 4 minutes. How many feet must the scuba diver descend in the fifth minute to meet the goal?

The scuba diver must descend 3 feet in the fifth minute to meet the goal.

Step-by-step explanation:

To find how many feet does the scuba diver need to descend to reach the goal of 35 feet in 5 minutes, we need to calculate how many feet he did descend on the first 4 minutes.

So, calculating we have:

First Minute = 9ft

Second Minute = 11ft

Third Minute = 5 ft

Fourth Minute = 7 ft

Total = 9 ft + 11ft + 5ft + 7ft = 32 ft

Goal = 35 ft

Needed = Goal - Total ( 4 minutes)

Needed = 35 ft - 32 ft = 3 ft

Hence, we can see that at the 4 minute, he has only descended 32ft. It means that he need to descend 3 feet more in the fifth minute.

i am not sure sorry : c

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
