You want to draw 2 kings from a 52 card deck. And you do it with replacement.
There are 4 kings in a standard deck. The probability of getting one of them is
4/52 on the first draw.
For the second draw the probability is the same.
4/52
The probability for both happening is
(4/52)*(4/52) = (1/13)*(1/13) = 1/169 = 0.001597
The volume of the shape
We have a cylinder that is cut into two. Its external radius is 5ft, while its internal radius is 4ft.
External radius = internal radius + thickness
![\begin{gathered} \text{External radius = 4ft + 1ft } \\ =\text{ 5ft} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BExternal%20radius%20%3D%204ft%20%2B%201ft%20%7D%20%5C%5C%20%3D%5Ctext%7B%20%205ft%7D%20%5Cend%7Bgathered%7D)
Internal radius = 4ft (given)
Recall that the volume(V) of a full cylinder is:
![V\text{ = }\pi r^2h](https://tex.z-dn.net/?f=V%5Ctext%7B%20%3D%20%7D%5Cpi%20r%5E2h)
Since the cylinder is cut into two, the volume(V) is:
![V\text{ = }\frac{\pi r^2h}{2}](https://tex.z-dn.net/?f=V%5Ctext%7B%20%3D%20%7D%5Cfrac%7B%5Cpi%20r%5E2h%7D%7B2%7D)
height (h) = 12ft (given)
The volume of the shape:
Answer:
75% voted
Step-by-step explanation:
you add the 75 to 19 to figure out the total amount of people in the club.
75+19=76
Then you divide the people who voted which is 57 by the total amount of people in the club which is 76
57/76=0.75
then you move the decimal two places to the left and you get 75%
Answer:
D) 4
Step-by-step explanation:
−9 + 12 + (unknown) + −8 = −1
<em>Start by going through and testing each option</em>
−9 + 12 + 2 + −8 =
3 + 2 + −8 =
5 + −8 =
−3
−3 ≠ −1
<em>A) 2 is not possible.</em>
−9 + 12 + −2 + −8 =
3 + −2 + −8 =
1 + −8 =
−7
−7 ≠ −1
<em>B) </em>−<em>2 is not possible.</em>
−9 + 12 + −4 + −8 =
3 + −4 + −8 =
−1 + −8 =
−9
−9 ≠ −1
<em>C) </em>−4<em> is not possible.</em>
<em>From this, D is looking like the answer. But to be sure, test it.</em>
−9 + 12 + 4 + −8 =
3 + 4 + −8 =
7 + −8 =
−1
−1 = −1
<em>D) 4 is the answer.</em>
