Which value is an input of the function
2 answers:
Answer:
D. 4
Step-by-step explanation:
We have been given graph of a function. We are asked to choose the value, which is input of the given function.
We know that input of a function is value of the independent variable. Upon looking at our given graph, we can see that x is independent variable.
All the values in domain of our a function will be input values.
We can see that domain of our given function is .
Our function is defined for x values that are greater than or equal to 1, so first three options are not correct choice.
Since our function is defined at , therefore, 4 is an input of the given function.

Answer:
The coefficient of variation for the systolic measurements is 12.8 %
The coefficient of variation for the diastolic measurements is 16.3 %
Therefore, we can conclude that the systolic measurements are less dispersed as compared to diastolic measurements.
Step-by-step explanation:
The coefficient of variation is the ratio of standard deviation of the data to the mean of the data. It shows the dispersion in the data set.
Coefficient of variation for the systolic measurements:
Mean = μ = (120 + 128 + 156 + 98 + 154 + 122 + 118 + 136 + 128 + 120)/10
Mean = μ = 1280/10
Mean = μ = 128
Standard deviation = σ =
Using excel the standard deviation is found to be
Standard deviation = σ = 16.4
Coefficient of variation = σ/μ
Coefficient of variation = 16.4/128
Coefficient of variation = 0.128
Coefficient of variation = 12.8%
Coefficient of variation for the Diastolic measurements:
Mean = μ = (79 + 76 + 75 + 51 + 92 + 87 + 59 + 64 + 72 + 81)/10
Mean = μ = 736/10
Mean = μ = 73.6
Standard deviation = σ =
Using excel the standard deviation is found to be
Standard deviation = σ = 12
Coefficient of variation = σ/μ
Coefficient of variation = 12/73.6
Coefficient of variation = 0.163
Coefficient of variation = 16.3%
Conclusion:
We can conclude that the systolic measurements (12.8%) are less dispersed as compared to diastolic measurements (16.3%).
