Answer:
6 hours.
Step-by-step explanation:
Let t represent the time taken by apprentice in hours to make a set of glasses when working alone.
Part of work completed by apprentice in one hour would be 
.
We have been given that a glassblower can produce a set of simple glasses in about 2 hours. So part of work completed by glassblower in one hour would be 
.
While working together, the job takes about 1.5 hours. So part of work completed by both in one hour would be 
.
Now we will equate sum of work competed by both in hour by work completed by both working together is one hour as:
Therefore, it will take 6 hours for the apprentice to make a set of glasses when working alone.
Answer:
1) If it is spun 250 times, it will not land on W 207 times.
2) If it is spun 100 times, it will land on N 17 times (rounded up).
3) 1 out of 6
4) It has the same answer as 1) <em>(If it is spun 250 times, it will not land on W 207 times.)</em>
Answer:
-1.96312>-2.2360
Step-by-step explanation:
first find -
which is -2.2360679775
now round it to match the lenth of the other problem
-1.96312...
-2.2360...
now remember that the bigger the negitive number, the smaller it really is,
so
-1.96312>-2.2360

Answer:
0.632
Step-by-step explanation:
Given that a homeowner is three times as likely to purchase additional jewelry coverage as additional electronics coverage
If probability of purchasing additional electronics coverage = p, then prob of purchasing jewelry coverage = 3p
The two events are independent hence joint probability is product of these two.
i.e. P(both) = 
This is given as 0.2
the probability that a homeowner purchases exactly one coverage.
= Prob he purchases I + prob he purchases II-2(prob he purchases both)
