Answer and Explanation:
The computation is shown below:
a. For the percentage of failures is
= Number of failures ÷ number of pacemakers tested
= 4 ÷ 90
= 4.4%
b. For Number of failures per unit-hour of operating time
= Number of failure ÷ total time - non-operating time
= 4 ÷ (5,000 × 90) - (5,000 ÷ 2 × 4)
= 4 ÷ (450,000 - 10,000)
= 4 ÷ 440,000
= 9.09 × 10^-6
= 0.00000909 failure per unit-hour
c. For Number of failures per unit-year is
= Failure ÷ unit year
= 0.0000090909 × 24 hours × 365 days
= 0.07963 failure per unit-year
Answer:
<u>Feedback</u>
Explanation:
In this question there is an example of feedback. This communication model occurred because after receiving the e-mail, the students asked the teacher about the message received via e-mail.
When a message is sent to a recipient and answered, feedback occurs. This answer is important for clear communication and for measuring the effectiveness of a message.
No, I feel that targeted advertising with cookies is not at all objectionable; rather, it is a very efficient technique for an organization to advertise and promote its products or services.
We commonly see files and pop-ups in our browsers when browsing the internet; these are cookies, and we typically encounter them at sites that we frequently visit. I feel that this is not at all offensive, but rather an efficient method of advertising and marketing things by segmenting the appropriate audience or prospective business.
Targeted advertising, or those customized ones that follow you across the internet containing products that you might really desire, have a lot of negative connotations: they're creepy, misleading, and possibly humiliating, among other things.

The expected value for the number of cars with defects can
be obtained by multiplying the probability of success (i.e. the percentage of
products with defects - 40%) by the number of cases (i.e. the number of cars
purchased – 5).
40 / 100 X 5 = 2
Therefore, the expected value for the number of cars with
defects will be the percentage of products with defects is 2
Answer:
Annual contributions to the retirement fund will be $6,347.31
Explanation:
First find the Present Value of the Annuity giving payments of $32,000 annually for 25 years at the rate of 10%.
Using a Financial Calculator enter the following data
PMT = $32,000
P/y = 1
N = 25
R = 10%
FV = 0
Thus, the Present Value, PV is $290,465.28
At the time of retirement (in 20 years time) the Value of the annuity fund is $290,465.28.
Next we need to find the Payments PMT to reach this amount in 20 years time at the interest rate of 8%
Using a Financial Calculator enter the following data
FV = $290,465.28
N = 20
R = 8 %
PV = $0
Thus, the Payments, PMT required will be $6,347.3080
Conclusion :
Annual contributions to the retirement fund will be $6,347.31
