What is independent. And what is dependent.

☻ ~~~~~~~~~~~~ Hello! ~~~~~~~~~~~~~~~ ☻

➴ Independent = P   Dependent = W

When you wait in line, sometimes there is less or more people. Sometimes, you wait longer than other days. If there are more people, the time will go up. If there are less people, the waiting time will go down. So, the wait is dependent on the number of people.

A submarine is searching for underwater features. It is accompanied by a small aircraft
Ivanshal [37]

Answer:

255 m

Step-by-step explanation:

From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.

Thus,

For the aircraft, its height = +200 m

For the submarine, its depth = -55 m

So that the difference between the submarine and aircraft can be determined as;

200 - (-55)

= 200 + 55

= 255 m

The distance between the submarine and aircraft is 255 m.

Im confused on this question on how to solve it​
Yakvenalex [24]

Answer:

9/4

Step-by-step explanation:

see image

2/3 is 2 × 1/3.

We can separate the exponent into 1/3 power raised to the 2nd power. 1/3 power is the same as cube root.

27 and 8 are both perfect cubes. 3^3 and 2^3.

Thats how you go from 27/8 to 3/2.

Then square it.

see image.
