the second on 222222222222
<span>The geometric average return is the the nth root of the product of the stock returns.
So we have nâš r1 * r2 * r3. Where n is the number of returns.
So we have 4âš(14.5 * 4.8 * 10.2 * 6 1)
This gives us 4âš ( 4330.512)
The fourth root of 4330.512 is 8.1121 percent.</span>
Answer: Yes, y does vary directly with x.
Constant of variation = 1/4
The function rule is y = (1/4)x
=========================================================
Explanation:
Let's assume that y does vary directly with x.
If that's the case, then we have an equation in the form y = kx, where k is the constant of variation.
Solving for k gets us k = y/x
For each row, divide the y value over the x value
- row one: k = y/x = 14/56 = 0.25
- row two: k = y/x = 20/80 = 0.25
- row three: k = y/x = 22/88 = 0.25
Each row yields the value k = 0.25 and it fully confirms y does vary directly with x.
So y = kx becomes y = 0.25x as the function rule, which is equivalent to y = (1/4)x
