dividing 11.5 by 5 gives you the unit rate, then you just multiply that answer by 2 and you should be okay
Count the amount of digits from right to left:
The digit 5 appears at the eighth position.
Remember that the 7th position is for millions. So, the eighth position is for ten millions.
Therefore, the place where the digit 5 sits in the number 952,832,744 is ten millions.

Step-by-step explanation:
1 and 1/2 is the right one
Answer:
Mean = 3.4
Variance = 1.088
Standard deviation = 1.0431
Step-by-step explanation:
![P=0.68\\ \\N=5](https://tex.z-dn.net/?f=P%3D0.68%5C%5C%20%5C%5CN%3D5)
The mean of a binomial distribution with parameters N (the number of trials) and p (the probability of success for each trial) is ![m=N\cdot p](https://tex.z-dn.net/?f=m%3DN%5Ccdot%20p)
Thus,
![m=5\cdot 0.68=3.4](https://tex.z-dn.net/?f=m%3D5%5Ccdot%200.68%3D3.4)
The variance of the binomial distribution is
, where
is the variance of the binomial distribution, so
![s^2=5\cdot 0.68\cdot (1-0.68)=3.4\cdot 0.32=1.088](https://tex.z-dn.net/?f=s%5E2%3D5%5Ccdot%200.68%5Ccdot%20%281-0.68%29%3D3.4%5Ccdot%200.32%3D1.088)
The standard deviation
is the square root of the variance
so
![s=\sqrt{1.088}\approx 1.0431](https://tex.z-dn.net/?f=s%3D%5Csqrt%7B1.088%7D%5Capprox%201.0431)
