Answer with explanation:</h2>
Let
be the average starting salary ( in dollars).
As per given , we have

Since
is left-tailed , so our test is a left-tailed test.
WE assume that the starting salary follows normal distribution .
Since population standard deviation is unknown and sample size is small so we use t-test.
Test statistic :
, where n= sample size ,
= sample mean , s = sample standard deviation.
Here , n= 15 ,
, s= 225
Then, 
Degree of freedom = n-1=14
The critical t-value for significance level α = 0.01 and degree of freedom 14 is 2.62.
Decision : Since the absolute calculated t-value (2.07) is less than the critical t-value., so we cannot reject the null hypothesis.
Conclusion : We do not have sufficient evidence at 1 % level of significance to support the claim that the average starting salary of the graduates is significantly less that $42,000.
Answer is choice C: If a line is drawn through point A and point X, then it will bisect line segment BC.
This line is the third missing median of the triangle. A median goes from one vertex to the midpoint of the opposite side. The midpoint cuts the segment in half. For example, median CD cuts segment AB in half (AD = DB). All three medians of a triangle meet at the same point: the centroid
Your answer is x=21/4
first you subtract 7/2 from both sides to isolate x
then you simplify
hope this helps:)
