Answer:
x=39
Step-by-step explanation:
First I try to find the angle measurements for the rest of the angles inside the triangle. I saw that the 68 degrees and I notice that it was vertical angles, meaning that the inside is also 68. I then notice that the 107 and the other unknown angle besides x must be 180 when adding up, so I can do 180-107=73. Now I know that that angle is 73 degrees I can find x by solving this equation 180=73+68+x, which the answer comes out to be 39. so x=39.

Answer:

Step-by-step explanation:
From the question we are told that:
Sample 1 
Sample 1 mean blood pressure 
Sample 1 variance 
Sample 2 
Sample 2 mean blood pressure 
Sample 2 variance 
Generally the equation for the test of statistic is mathematically given by



therefore the samples test for comparing the two population means

6.3
0.05
0.872
0.0.18
