Answer:

- 1320 feet.

Step-by-step explanation:

The submarine starts at - 1260 feet in relation to the sea level.

Now, it descends 5 feet per minute for 12 minutes.

We have to find the new position of the submarine with respect to sea level.

Hence, the new position of the submarine will be - 1260 + (- 5)(12) = - 1260 - 60 = - 1320 feet with respect to sea level. (Answer)

What is the mean median and mode of 99, 69, 96, 69, 78. Round to the nearest tenth if necessary
KiRa [710]
A median is the middle number of a data set.
To find it put the numbers in order.
78, 69, 69, 96, 99
Then find the middle number
78, 69, *69,* 96, 99

The median is 69

A mode is the number that appears the most in a set of numbers.
78, *69, 69,* 96, 99

The mode is 69

To find the mean or average of a set of numbers, add all the numbers together then divide by the number of numbers there are.
99+69+96+69+78 = 411
411/5 = 82.2

The mean is 82.2

Hope this helped! If you have anymore questions or don't understand, please comment on my profile or DM me. :)
