Answer:
30 yrs
Step-by-step explanation:
SI = PRT/100
T = I × 100/PR
= 9000×100/1500×20
= 900000/30000
= 30 yrs
Answer:
The equation of the least-squares regression line for this plot is approximately ŷ = 3.8 + two thirds times x.
Step-by-step explanation:
When we add two equations, it's important to <em>combine like terms</em>
<u>x's with x's </u>
<u>y's with y's </u>
<u>and constants with constants</u>
2x + 5x = 7x
3y + (-y) = 2y
-5 + -12 = -17
Let's put <em>everything together </em>for a final equation
7x + 2y - 17 = 0
or
7x + 2y = 17
