Nehemiah wants to create a function to represent the change in his income over the past few months. Nehemiah estimates that the

best fit linear function for the change in his income is y=2310+220x, where y is his monthly income and x is the number of months.
The predicted value of Nehemiah's income in month 6 is (3540/3630/3760/3850) $________. If the actual value of Nehemiah's income was $3750 in month 6, the residual value for month 6 would be (210/120/-15/-100/-120)

Answer: The predicted value of Nehemiah's income in month 6 is $3,630.If the actual value of Nehemiah's income was $3750 in month 6, the residual value for month 6 would be $120.

Step-by-step explanation:

Hi, to answer this question we have to substitute x = 6 (moths) in the equation given:

y=2310+220x

Replacing:

y=2310+220(6)

Solving:

y=2310+1320

y = $ 3630

The predicted value of Nehemiah's income in month 6 is $3,630.

If the actual value of Nehemiah's income was $3750 in month &, the residual value will be equal to the actual value minus the predicted value.

3750-3630=$120
