Answer:
(24r-10)/2
Step-by-step explanation:
12r-5 Lets multiply everything by 2 since we are given nothing to simplify
24r-10 now we have to make it equivalent to 12r-5
So all we will do is put it in a fraction bar
24r-10 is the numerator and 2 is the denominator
So the final result is: (24r-10)/2
Answer:
The standard error for her sample is SE = 0.6095
Step-by-step explanation:
By definition, the standard error of the mean is:
![SE = \frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=SE%20%3D%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Where:
is the standard deviation
is the sample size.
For the information provided in the problem we know that:
![\sigma = 8.62](https://tex.z-dn.net/?f=%5Csigma%20%3D%208.62)
![n = 200](https://tex.z-dn.net/?f=n%20%3D%20200)
Then we introduce these values in the formula of the error to obtain the value.
![SE = \frac{8.62}{\sqrt{200}}](https://tex.z-dn.net/?f=SE%20%3D%20%5Cfrac%7B8.62%7D%7B%5Csqrt%7B200%7D%7D)
![SE = 0.6095](https://tex.z-dn.net/?f=SE%20%3D%200.6095)
