I think it d infinitely many solutions
Answer:
H0 : u = 8500
H1 : u > 8500
Step-by-step explanation:
Given:
sample size, n = 350
mean, u = 8500
Sample mean, x' = 8745
Standard deviation = 1,200
Level of significance = 0.05
In this case, the financial administrator believes that the average cost of tution, room and board at small liberal arts colleges is higher than the reported $8500. We can say this is the alternative hypoyhesis, since it is a claim.
The null hypothesis would be the opposite of the alternative hypothesis.
Therefore, the null and alternative hypotheses are:
H0 : u = 8500
H1 : u > 8500

Answer:
DC= 32.3 units
Step-by-step explanation:
Use Pythag theorem to find BC first
15 ^2 + BC ^2 = 22^2 then BC = sqrt 259
Then use the Pythagorean Theorem again to find DC
DC^2 = 28^2 + sqrt(259)^2
DC=32.3
