Answer: The diver is 23 feet under sea level
Step-by-step explanation:
If we draw a vertical number line (image attached), where point 0 is sea level (the diver's initial position), the first point under sea level is -20, since we are told it dives a distance of 20 ft (the negative sign is only to indicate the direction, since a distance cannot be negative).
Then, the diver goes 10 ft deep. This means now it is 30 ft under sea level and the second point is -30.
After that the diver swims up 12 ft, hence we have to count 12 points up in our number line and the corresponding point is -18.
Finally, the diver swims 5 ft lower and keep that position. Hence, we have to count 5 points below point -18 in the number line, resulting in the last point: -23.
This means the diver's final position is 23 feet under sea level.
If we want to prove it with numbers, we can do it as follows:
20 ft (down)+10 ft (down)-12 ft (up)+5 ft (down)=23 ft

Number of hours left to work(x) = 15 hours - (3 hours/day)x
Note how this Number of hours decreases steadily from its initial value (15 hours) at the rate of 3 hours/day. The domain of x is [0,5].

Step-by-step explanation:
Since the question said they were approximate it means that the difference between every side's length is the amount added to the smaller one to get the bigger triangle. You find the difference (which is 2,by the way (7-5 or OC-OU)) of the given side's and relate their similarities (in this case we'll add, so it's the difference plus the other side). We've been given TU as 4 so ST=TU+2, ie. 4+2=ST

Answer:
Most of the songs were between 3 minutes and 3.8 minutes long.
Step-by-step explanation:
We can see that the "bell" part of this distribution goes from 3 to 3.8. This is where the majority of data is in a normal distribution.
This means that the majority of the songs were between 3 and 3.8 minutes long.
