Answer:
From the empirical rule we know that we have within one deviation from the mean 68% of the values, within two deviations 95% and within 3 deviations 99.7%. We want to find the following probability:
![P( X](https://tex.z-dn.net/?f=%20P%28%20X%3C7.2%29)
We can use the z score formula given by:
![z = \frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=%20z%20%3D%20%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
And replacing we got:
![z = \frac{7.2-10}{1.4}= -2](https://tex.z-dn.net/?f=%20z%20%3D%20%5Cfrac%7B7.2-10%7D%7B1.4%7D%3D%20-2)
So we want to find the probability that the data lies below 2 deviations from the mean and using the empirical rule we got:
![(1-0.95)/2 = 0.025](https://tex.z-dn.net/?f=%20%281-0.95%29%2F2%20%3D%200.025)
Step-by-step explanation:
For this problem we know that the average lion lives with a mean of
and the deviation is ![\sigma =1.4](https://tex.z-dn.net/?f=%5Csigma%20%3D1.4)
From the empirical rule we know that we have within one deviation from the mean 68% of the values, within two deviations 95% and within 3 deviations 99.7%. We want to find the following probability:
![P( X](https://tex.z-dn.net/?f=%20P%28%20X%3C7.2%29)
We can use the z score formula given by:
![z = \frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=%20z%20%3D%20%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
And replacing we got:
![z = \frac{7.2-10}{1.4}= -2](https://tex.z-dn.net/?f=%20z%20%3D%20%5Cfrac%7B7.2-10%7D%7B1.4%7D%3D%20-2)
So we want to find the probability that the data lies below 2 deviations from the mean and using the empirical rule we got:
![(1-0.95)/2 = 0.025](https://tex.z-dn.net/?f=%20%281-0.95%29%2F2%20%3D%200.025)
The answer is four because 2 x 0 is 0 and then 12 divided by 3 is for
THE ANSWER IS 4
They are equivalent. They’re equivalent because 3+6=9 and 3(2+1) also equals 9 2+1 is 3 so you would have 3(3) and whatever number is in the parentheses you just multiply it with the other number and 3*3 is 9
