Asked by Jen

In each of the four examples listed below, one of the given variables is independent (x) and one of the given variables is dependent (y). Indicate in each case which variable is independent and which variable is dependent.
I. Rainfall; Crop yield
II. Taxi fare; Length of ride
III. Alcohol consumption; Blood alcohol level
IV. Average annual snowfall; Geographic location

I got:
I. Dependent variable; Independent variable
II. Independent variable; Independent variable
III. Independent variable; Dependent variable
IV. Dependent variable; Dependent variable


Please let me know if its correct?

1. Are you saying crop yield causes rainfall?

2. Both cannot be independent variables. It would help if you proofread your questions before you posted them.

3, 4. Right.

the value of the dependent variable in function is always______ the value of the independent variable.

determined by or influenced by the value of the independent variable.

To find the outputs for the given inputs in the function y = 2x - 4, we substitute the input values for x and simplify:

When x = 6, y = 2(6) - 4 = 8
When x = 2, y = 2(2) - 4 = 0
When x = -4, y = 2(-4) - 4 = -12

Therefore, the set of output values that correctly completes the function table is y = 8, 0, -12 for inputs 6, 2, -4 respectively.

The rule for the given function table is:

y = 0.5x

We can see this by dividing each input value by 2, which gives us the corresponding output value. For example:

- When x = 24, y = 0.5(24) = 12
- When x = 12, y = 0.5(12) = 6
- When x = -12, y = 0.5(-12) = -6

So, the pattern is to multiply the input by 0.5 to get the output.
