Answer:
Step-by-step explanation:
We have been given that point O is the in-center of triangle ABC. We are asked to find the measure of angle QBO.
We know that in-center of a triangle is the point, where three angle bisectors of triangle meet.
Since O is in-center, so AO will be angle bisector. We will find the value of x by equating the expression for angle QAO to angle SAO as:
Now we will substitute in the expression for measure of angle QBO.
Therefore, the measure of angle QBO is 12 degrees.

Answer:
Null hypothesis:
Alternative hypothesis:
The statistic to check the hypothesis is given by:
And is distributed with n-2 degrees of freedom
And the statistic to check the significance of a coeffcient in a regression is given by:
For this case is importantto remember that t1 and p value for test of slope coefficient is the same test statistic and p value for the correlation test so then the answer would be:
Always
Step-by-step explanation:
In order to test the hypothesis if the correlation coefficient it's significant we have the following hypothesis:
