Answer:

h= $h= \frac{5R^{3} }{LU}$

Step-by-step explanation:

1.) You must isolate the h from the equation by dividing both sides by L (or multiply by its reciprocal, which in this case, the reciprocal on L is $\frac{1}{L}$ .....So it would look like:

$(\frac{1}{L} )*\frac{5R^{3} }{U} = \frac{L}{h}* (\frac{1}{h} )\\$

2.) Simplify the equation if you need to (in this case, its not needed)

$\frac{5R^3}{LU} =h$

That's your answer :)

Write the equation of the line in fully simplified slope-intercept form.

iren2701 [21]

Y=Mx+b

Rise / run between any two points = slope (m)
Where the line crosses the y axis is (yint) (b)

Slope is -1/2
Yint = -8

So the equation is y=(-1/2)x - 8

Answer:

The co variance of the midterm and final exam scores is 58.76.

Step-by-step explanation:

The formula to compute the sample co variance is:

$Cov(x,y)=\frac{\sum(X-Mean\ of\ X)(Y-Mean\ of\ Y)}{n-1}$
