285 didn't go. bc u subtract the percent and 350
Answer:
y -6 = 0
Step-by-step explanation:
hello :
Use the point-slope formula.
y - y_1 = m(x - x_1) m=0 x_1= 4 y_1 = -3
an equation for this line is : y -6 = 0(x -4)
y -6 = 0
Answer:
There are 22 or 33 students
Step-by-step explanation:
Answer:
Step-by-step explanation:
For this case we want to find the density function for 
And we have the following density function for the random variable X:

So we can do this replacing 

If we apply square root on both sides we got:

And if we integrate we got this:
![F_Y (y) = [t+ \frac{t^2}{2}] \Big|_{-\sqrt{y}}^0+ [t -\frac{t^2}{2}] \Big|_{0}^{\sqrt{y}}](https://tex.z-dn.net/?f=%20F_Y%20%28y%29%20%3D%20%5Bt%2B%20%5Cfrac%7Bt%5E2%7D%7B2%7D%5D%20%5CBig%7C_%7B-%5Csqrt%7By%7D%7D%5E0%2B%20%5Bt%20-%5Cfrac%7Bt%5E2%7D%7B2%7D%5D%20%5CBig%7C_%7B0%7D%5E%7B%5Csqrt%7By%7D%7D%20)
And replacing we got:
![F_Y (y) = [0 -(-\sqrt{y} +\frac{y}{2})] + [\sqrt{y} -\frac{y}{2}]](https://tex.z-dn.net/?f=%20F_Y%20%28y%29%20%3D%20%5B0%20-%28-%5Csqrt%7By%7D%20%2B%5Cfrac%7By%7D%7B2%7D%29%5D%20%2B%20%5B%5Csqrt%7By%7D%20-%5Cfrac%7By%7D%7B2%7D%5D)

And if we want to find the density function we just need to derivate the pdf like this:
