Answer:
3/7 and 1/7 =4/7is the right answer i just did it and put there answers in but all of them was wrong they said theses are the answers
Step-by-step explanation:
There are 11 slips of paper in the box, and 4 of them have vowels on them.
Chance of picking a vowel the first time = 4/11 .
If successful, then there are 10 slips left in the box, and 3 of them are vowels.
Chance of picking a vowel the second time = 3/10 .
Probability of BOTH events = (4/11) x (3/10) = 12/110 = 10.91% .

B is the area of the base
h is the height of the pyramid
in this problem we have that
B is a square

so
substitute in the formula of volume
![V=\frac{1}{3}*x^{2}*(x+2)\\ \\V=\frac{1}{3}*[x^{3} +2x^{2}]\ cm^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%2Ax%5E%7B2%7D%2A%28x%2B2%29%5C%5C%20%5C%5CV%3D%5Cfrac%7B1%7D%7B3%7D%2A%5Bx%5E%7B3%7D%20%2B2x%5E%7B2%7D%5D%5C%20cm%5E%7B3%7D)
