You can take the mean of each category (assuming it is evenly distributed) and calculate the mean as (10x4 + 30x3 + 50x2 + 70x1) / (4+3+2+1) = 300/10 = 30

Which expression is equivalent to sqrt128x^5y^6/2x^7y^5 ? Assume x 0 and y > 0.

kolbaska11 [484]

<u>Answer:</u>

$\frac{8\sqrt{y} }{x}$

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it:

$\sqrt {\frac {128x^5y^6} {2x^7y^5} }$

To make it easier to solve, we can also write this expression as:

$\sqrt {\frac{128}{2} * \frac {x^5} {x^7} * \frac {y^6} {y^5}}$

Now we will cancel out the like terms to get:

$\sqrt {64*\frac{1} {x^2}*y }$

Taking the square root of the terms to get:

$8*\frac {1}{x} .\sqrt{y}$

$\frac{8\sqrt{y} }{x}$
