2. a submarine starts out at 135 feet below sea level. it dives 239 feet before rising 307 feet. represent the current depth of the submarine as an integer.

The submarine is at 67 feet below the sea level (-67)

Step-by-step explanation:

* Lets explain how to solve the problem

- The zero level is the sea level

- Any height below the sea level is negative

- Any height above the sea level is positive

- A submarine starts out at 135 feet below the sea level

∴ The submarine is at -135 feet

-  The submarine dives 239 feet before rising

∴ The submarine dives another -239

∴ The submarine is at -135 + -239 = -374 feet

* The submarine is at 374 feet below the sea level

- The submarine rising 307 feet

∴ The submarine dives 307 feet up

- Add the last position to the rising distance

∴ The current depth of the submarine = -374 + 307 = -67 feet

∴ The submarine is at 67 feet below the sea level

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
