Answer:
Step-by-step explanation:
You can make equations.
M+J=51
M-J=17
Subtracting first equation from second equation:
2J=34
J=17 Jordan is 17
Therefore, Mike, is 34.
Well if the cubic unit is one, then we can assume that the domain is -1<0
Answer: One tail test.
Step-by-step explanation:
Given : A sample of 36 observations is selected from a normal population. The sample mean is 12, and the population standard deviation is 3.
Also, The set of hypothesis to conduct a test :-

The kind of test need to perform is dependent upon the alternative hypothesis.
Since, the alternative hypothesis is one tailed (right-tailed), so the test is one tail test.
Y=1/2x+2 since the slope is 1/2 and the y intercept is 2
