2*4*8 is 64 2*4 is 8 and 8*8 is 64
Answer:
![y = 0.00587x +1986.406](https://tex.z-dn.net/?f=y%20%3D%200.00587x%20%2B1986.406)
Step-by-step explanation:
Given that the population of a city increased steadily over a ten-year span. The following ordered pairs show the population x and the year y over the ten-year span in the form (x, y) for specific recorded years.
x y
2500 2001
2650 2002
3000 2004
3500 2007
4200 2011
Slope 0.005865485
Intercept 1986.406413
So regression line is
![y = 0.00587x +1986.406](https://tex.z-dn.net/?f=y%20%3D%200.00587x%20%2B1986.406)
When population = 15000
![0.00587(17000)+1986.406\\=2074.389](https://tex.z-dn.net/?f=0.00587%2817000%29%2B1986.406%5C%5C%3D2074.389)
You have the formula already, just plug in 30 for s (speed) and solve for d (distance).
