This graph shows the balance of a savings account after w weeks, where the money is being deposited at a constant rate. What is the independent variable?

473

Step-by-step explanation:

Number of weeks

Step-by-step explanation:

The independent variable in an equation is one you can freely change. In the equation y = 3x + 2, for instance, x is our independent variable. We can plug in anything we'd like for x and through pure arithmetic, get a value out for y. If we picked x = 2, then y = 3(2) + 2 = 6 + 2 = 8. The dependent variable in this example is y, since it depends on the value of x we pick.

In this problem, the total savings in our account depends on the number of weeks it's deposited for, so the savings is our dependent variable, and the number of weeks w is our independent variable.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

no this is a nonlinear negative
