a. The marginal densities

$f_X(x)=\displaystyle\int_0^1(x+y)\,\mathrm dy=x+\frac12$

and

$f_Y(y)=\displaystyle\int_0^1(x+y)\,\mathrm dx=y+\frac12$

b. This can be obtained by integrating the joint density over [0.25, 1] x [0.5, 1]:

$P(X>0.25,Y>0.5)=\displaystyle\int_{1/4}^1\int_{1/2}^1(x+y)\,\mathrm dx\,\mathrm dy=\frac{33}{64}$

Slope intercept form is: y = mx + b

Isolate the y. First subtract 10x from both sides

10x (-10x) + 2y = 8 (-10x)

2y = -10x + 8

Isolate the y. Divide 2 from both sides and <em>all</em> terms.

(2y)/2 = (-10x + 8)/2

y = -5x + 4

y = -5x + 4 is your slope intercept form answer.

hope this helps

I think since he runs 3 yards per hour per second their are 60 seconds in a minute so 60 times equals 180 yards per second
