Yes
Step-by-step explanation:
Yes, that is possible because whenever one number is a factor of the other one, it's their greatest common factor. Here are some examples.
2 and 200
10 and 100
13 and 52
one thousand and one million
52% of 200
52/100=26/50=13/25•200/1= 2600/25=2600 divided by 25 is 104

Answer:


Step-by-step explanation:
For this case we have the following info given:
Weight before diet 180 125 240 150
Weight after diet 170 130 215 152
We define the random variable
and we can calculate the inidividual values:
D: 10, -5, 25, -2
And we can calculate the mean with this formula:

And the deviation with:

And after replace we got:

And the confidence interval for this case would be given by:

The degrees of freedom are given by:

For the 95% of confidence the value for the significance is
and the critical value would be
. And replacing we got:
