So 8 and 1/2 of 100
'of' means multiply
8 and 1/2 times 100=8 times 100+100 times 1/2=800+50=850
the answer is 850
Answer: b
Step-by-step explanation:
Indpendent events.
Probability of a child be a boy: 1/2
Probability of a child be a girls: 1/2
Combined probability of the event boy/girl/boy/girl = 1/2*1/2*1/2*1/2=1/16=0.0625
If the biologist catches and tags 32 bass and from sample of 55 he found only 5 tagged then there are 352 bas in the lake.
Given Biologist catches and tags 32 bass, when sample of 55 bass is taken then 5 are found tagged.
Population is basically number of living thing exists in a particular area.
Number of bass which are tagged in lake=32
Sample size=55
Number of bass found tagged=5
means percentage of tagged bas found is 5/32*100=1.6%
We have to calculate number of times 5 is multiplied to get 32 which is 6.4.
Number of bass in the lake=55*6.4
=352 basses.
Hence there are 352 basses in the lake if 5 are found tagged in a sample of 55.

Answer:
![A=5940\ unit^2](https://tex.z-dn.net/?f=A%3D5940%5C%20unit%5E2)
Step-by-step explanation:
Given that,
The area of a circle, ![A=36\pi](https://tex.z-dn.net/?f=A%3D36%5Cpi)
Central angle,
= 330
We need to find the area of the sector. The formula for the area of sector is given by :
![A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{330}{360}\times 36\times 180\\\\A=5940\ unit^2](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B%5Ctheta%7D%7B360%7D%5Ctimes%20%5Cpi%20r%5E2%5C%5C%5C%5CA%3D%5Cdfrac%7B330%7D%7B360%7D%5Ctimes%2036%5Ctimes%20180%5C%5C%5C%5CA%3D5940%5C%20unit%5E2)
So, the area of the sector is equal to
