Answer:
A cost is something you have to give up or sacrifice and a benefit is something that is gained or is helpful.
Explanation:
In a cost-benefit analysis of a system, an engineer is to simply look at the requirements for the system and determine the costs to build the system, both in financial value and energy value. Additionally, the engineer needs to determine the benefits that would come from choosing a particular path of cost. If the benefits outweigh the cost for the project, then the solution is accepted. Else, the cost outweighs the benefit and the solution is rejected.

Mark me please as brainliest
Explanation:
A length of pipe will weigh the most when O A. part dimensions are such that the pipe is in the MMC. O B. the OD and ID are at the minimum allowable limit. OC. the OD and ID are at the maximum allowable limit. OD.part dimensions are such that the pipe is in the LMC
Answer:
Now we can decide based on the significance level . If we reject the null hypothesis and in other case we FAIL to reject the null hypothesis.
we see that so then we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly less than 15
we see that so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is NOT significantly less than 15
we see that so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is NOT significantly less than 15
Explanation:
For this case they conduct the following system of hypothesis for the ture mean of interest:
Null hypothesis:
Alternative hypothesis:
The statistic for this hypothesis is:
And on this case the value is given
For this case in order to take a decision based on the significance level we need to calculate the p value first.
Since we have a lower tailed test the p value would be:
Now we can decide based on the significance level . If we reject the null hypothesis and in other case we FAIL to reject the null hypothesis.
we see that so then we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly less than 15
we see that so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is NOT significantly less than 15
we see that so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is NOT significantly less than 15
Answer:
a.
y[n] = x[n] x[n-1] x[n+1]
(i) Memory-less - It is not memory-less because the given system is depend on past or future values.
(ii) Causal - It is non-casual because the present value of output depend on the future value of input.
(iii) Invertible - It is invertible and the inverse of the given system is
(iv) Stable - It is stable because for all the bounded input, output is bounded.
(v) Time invariant - It is not time invariant because the system is multiplying with a time varying function.
b.
y[n] = cos(x[n])
(i) Memory-less - It is memory-less because the given system is not depend on past or future values.
(ii) Causal - It is casual because the present value of output does not depend on the future value of input.
(iii) Invertible - It is not invertible because two or more than two input values can generate same output values .
For example - for x[n] = 0 , y[n] = cos(0) = 1
for x[n] = 2 , y[n] = cos(2) = 1
(iv) Stable - It is stable because for all the bounded input, output is bounded.
(v) Time invariant - It is time invariant because the system is not multiplying with a time varying function.
Answer:
hello your question is poorly written attached below is the correct question
answer : y(t) = 1.5 + 0.025 sin( 600t - 0.259 ) v
Explanation:
Given data:
Time constant = 5msec
static sensitivity = 0.05 v/°c
f = 100 hz
ε = 0.8
T(t) = ( 30 + 2.5 sin600t )°C
<em>attached below is a detailed solution to the question above </em>
