Answer:

The constant of variation is -4

Step-by-step explanation:

If y is directly proprtional to x, then we write:

y \propto \: x

If we introduce the constant of proportionality or variation k, then we obtain:

y = kx

When x=1, y=-4 (We can choose any ordered pair from the table)

- 4 = k(1)

k =  - 4

Therefore the constant of variation is -4.

Answer:  The "independent variable" is the "time" (in hours) that is plotted on the "x-axis".  Note the "time" (in hours) can be "manipulated" in the sense that is it "chosen" by the humans who are measuring the data (e.g. when to start, how many hours, and at what intervals.

The "dependent variable" is the measurement (in feet) above or below the sea level, and this is plotted on the "y-axis".  These values cannot be "manipulated" in the sense that one cannot "choose" what value or measurement the tide level would be at any particular time.

Hope these answers—and explanations—are of help to you.
Best wishes!

Step 1: Multiply both sides by 5.

4x = 2

(4x) * (5) = (2) * (5)
5

4x = 10

Step 2: Divide both sides by 4.

4x = 10

2. The probability of tossing 2 tails and 1 head is 3/8.

3. The probability of getting exactly 1 tail is 3/8. The probability of tossing at least 2 heads is 4/8 or 1/2. There is a greater chance of tossing at least 2 heads than tossing exactly 1 tail.
