Answer:
Hypotenuse is the longest side in a triangle.
a^2=b^2+c^2.
5^2=4^2+c^2.
c^2=25-16.
c^2=9.
c=√9.
c=3cm.
did he work?
The answer is 50.5 hours
all you have to do is add all the hours up to get the grand total.
Hope this helps
have a great day!
(b) What is the probability that a participant chosen at random was not satisfied with their service?
Answer:
(a) The probability is 31.44%
(b) The probability is 9.345%
Step-by-step explanation:
The probability for part (a) is calculated as a multiplication of:
65.5% * 48% = 31.44%
Where 65.5% is the percentage of participants that had not switched service in the past 3 years and 48% are the percentage of those 65.5% that were very satisfy. So, the 31.44% of the participants had not switched service in the past 3 years and were very satisfied with their service.
Then, for part b, we have 2 cases:
So, the probability is calculated as a sum of these two probabilities.
Therefore, the probability for case 1 is calculated as:
34.5% * 10% = 3.45%
Where 34.5% is the percentage of participants that had switched service in the past 3 years and 10% are the percentage of those 34.5% that were not satisfy.
At the same way, the probability for case 2 is:
65.5% * 9% = 5.895%
Finally, the probability that a participant chosen at random was not satisfied with their service is the sum of 3.45% and 5.895%. That is:
3.45% + 5.895% = 9.345%
2 = 4
