With math constructed 1. find the least squares regression equation using the school year (in number of years after 2000) for the input variable and the average cost (in thousands of dollars) for the output variable. 2. what is the best estimate for the average cost of tuition at a 4-year institution starting in 2000. 3. what is the best estimate for the average cost of tuition at a 4-year institution starting in 2020. 4. what does the slope mean in context of the situation? 5. most students are not able to afford this tuition for 4 years. what are some ways that you can lower the cost of your college tuition? if you don’t plan to attend college, what things can do you post- hs graduation to continue your education or provide for yourself financially?

Step-by-step explanation:

1. For this sort of question a graphing calculator or spreadsheet are suitable tools. The attached shows the linear regression line to have the equation ...

... y = 0.937976x + 12.765

where x is years since 2000, and y is average tuition cost in thousands.

2. The y-intercept is the year-2000 tuition: $12,765.

3. Evaluating the formula for x=20 gives y ≈ 31.524, so the year-2020 tuition is expected to be $31,524.

4. The slope is the rate of change of tuition with respect to number of years. It is the average increase per year (in thousands). It amounts to about $938 per year.

5. [not a math question]

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

3x + 4y -25 =0 represents the amount of change sianna should recieve
