Answer:
16920
Step-by-step explanation:
6% of 18000 is 1080 so 18000-1080 is 16920
Answer:
132cm^2
Step-by-step explanation:
SA of square based pyramid:
SA = 2bs + b^2
b = base
s = slant height
-> 2(6)(8) + 6^2
-> 96 + 36
= 132cm^2
Answer:
50%
Step-by-step explanation:
29 is half of 58 = 50% decrease
Answer:
![P(Female\ or\ Physics) = 0.38](https://tex.z-dn.net/?f=P%28Female%5C%20or%5C%20Physics%29%20%3D%200.38)
Step-by-step explanation:
Given
--- total
![Physics =10](https://tex.z-dn.net/?f=Physics%20%3D10)
![Female= 12](https://tex.z-dn.net/?f=Female%3D%2012)
![Both = 3](https://tex.z-dn.net/?f=Both%20%3D%203)
Required
![P(Female\ or\ Physics)](https://tex.z-dn.net/?f=P%28Female%5C%20or%5C%20Physics%29)
This is calculated as:
![P(Female\ or\ Physics) = P(Female) + P(Physics) - P(Both)](https://tex.z-dn.net/?f=P%28Female%5C%20or%5C%20Physics%29%20%3D%20P%28Female%29%20%2B%20P%28Physics%29%20-%20P%28Both%29)
So, we have:
![P(Female\ or\ Physics) = \frac{Female+ Physics - Both}{n}](https://tex.z-dn.net/?f=P%28Female%5C%20or%5C%20Physics%29%20%3D%20%5Cfrac%7BFemale%2B%20Physics%20-%20Both%7D%7Bn%7D)
![P(Female\ or\ Physics) = \frac{10+ 12- 3}{50}](https://tex.z-dn.net/?f=P%28Female%5C%20or%5C%20Physics%29%20%3D%20%5Cfrac%7B10%2B%2012-%203%7D%7B50%7D)
![P(Female\ or\ Physics) = \frac{19}{50}](https://tex.z-dn.net/?f=P%28Female%5C%20or%5C%20Physics%29%20%3D%20%5Cfrac%7B19%7D%7B50%7D)
![P(Female\ or\ Physics) = 0.38](https://tex.z-dn.net/?f=P%28Female%5C%20or%5C%20Physics%29%20%3D%200.38)
