Answer:
and 
Step-by-step explanation:
The null hypothesis 
states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form 
In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form .
The alternative hypothesis 
states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms
The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use as his alternative hypothesis.
Answer:
D
Step-by-step explanation:
Replace R1 with 1 and R3 with 0 you have -2(1)+0 which equals 0 and that matches matrix II. Repeat the process with the other numbers in R1 and R3 and they all come out equal therefor the answer is D.

which it will be 19.31
Answer:
6:10.
Step-by-step explanation:
4 : 40 + 1 : 30 = 5 : 70
because 60 minutes make an hour and on the minutes side has more than 60, we have to minus 60 minutes and carry the one hour to the other side which is the Hour side.
5 : 70........ minus 60 to get 10.
5 + 1 to get 6.
therfore it is 6 : 10
