Answer:
5 hours is the least amount of time possible
Step-by-step explanation:
It should be A. Find this by plugging the second equation into the first one. Then, try out each x-value from the answers to see which one makes sense
The answer is positive 0.8571
The hypothesis testing for this problem is:
a. The hypothesis for this problem are:
Null: H0: μ=6
Alternative: Ha: μ≠6
b. Test
T-statistics = (6.08 - 6) / 0.44* √(121) = 2
c. P value = 0.047759
Since our p-value is smaller than the significant level of 0.05, we can say that we reject the null hypothesis.
Conclusion: there is enough evidence to say lathe is not in perfect adjustment.
The correct answer is A. 120 ft squared because you must multiply the height times the width which comes to 120.
