No, you would do 100 - 64 because 10^2 is 100 and 8^2 is 64.
100-64= 36
The square root of 36 is 6. The length of the other leg is 6.
Answer:
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14* (4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)h
=(1/3)*3.14**9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7
Step-by-step explanation:
2:3 because if you simplify the ratio by 2
Answer:
Mean = 160 births
Variance = 156.8 births
Standard deviation = 12.522 births
Step-by-step explanation:
The mean number of births resulting in twins is given by the sample size (n=8000 births) multiplied by the probability of twins in any birth (p=2%).
In a binomial distribution like this one, the variance is given by:
The standard deviation is simply the square root of the variance:
