Answer:

And we can find this probability like this:

And we can replace the values and we got:

Step-by-step explanation:
For this case we define the random variable Y as: the number of slices of cheesecake left on the platter after the first serving. And we have the following distribution for Y:
Y | 0 1 2 3 4
P(Y) | 0.005 0.114 0.429 0.381 0.071
And we want to find the following probability:

And we can find this probability like this:

And we can replace the values and we got:

V of w sphere =


r³
Multiply by 3 on either sides to get rid of the fraction.

3V = 4

r³
Now divide either sides by 4

to isolate r³

r³
4

and 4

cancels out

= r³
Take the cube root to isolate r.
![\sqrt[3]{ \frac{3V}{4 \pi } } = \sqrt[3]{r^3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B3V%7D%7B4%20%5Cpi%20%7D%20%7D%20%3D%20%20%5Csqrt%5B3%5D%7Br%5E3%7D%20)
the cube root cancels the cube
= r
x - price of a video tape
y - price of a DVD

<h3>Answer: video tape cost $19 and DVD cost $32.</h3>
Answer:
A
Step-by-step explanation:
300 minus 15 ( times each week that passed) would equal how much she owes
Since there's a common denominator, you can go straight into subtracting,
so for the top, x^2 + 8x - x^2 -2x + 6 will simplify to -6x -6 which with the bottom can be reduced (dividing everything by 3) to 2x - 2/x^2 + x
