Well 3x is 3 times if they are together beside each other that mean they are multiplying so 3 times x plus 5times y = -5
Answer:
The value of the test statistic is 
Step-by-step explanation:
The formula for the test statistic is:

In which X is the statistic,
is the mean,
is the standard deviation and n is the number of observations.
In this problem, we have that:

So



The value of the test statistic is 
Answer:
<h2>
x = 90° - 30° = 60°</h2>
Step-by-step explanation:
Angles CGE and 30° are vertical angles.
Thus, Angle CGE is thus 30°.
Angle CGE and Angle x are complementary, so x = 90° - 30° = 60°
