Answer:
12:40 is the anwser
Step-by-step explanation:
If his flight leaves at 3:15 and it takes and hour and 35 minutes to gett there than you would have to subtract 1 hour and 35 minutes from 3:15 so
3:15 minus 1 hour is 2:15
2:15 minus 35 minutes is 1:40
so now he wants to be and hour and 35 minutes earlier so the anwser would be
2:15 minus 1 hour is 1:15
1:15 minus 35 minutes is 12:40
Answer:
∠a=40°
Step-by-step explanation:
complement of angle a=90-a
supplement of angle a=180-a
90-a=1/2(180-a)-20
multiply by 2
180-2a=180-a-40
180-180+40=-a+2a
a=40
Answer:
The objective of the confidence interval is to give a range in which the real mean of the population is placed, with a degree of confidence given by the level of significance.
The conclusion we can make is that there is 95% of probability that the mean of the population (professor's average salary) is within $99,881 and $171,172.
Step-by-step explanation:
This is a case in which, from a sample os size n=16, a confidence interval is constructed.
The objective of the confidence interval is to give a range in which the real mean of the population is placed, with a degree of confidence given by the level of significance. In this case, the probability that the real mean is within the interval is 95%.
