The relation represented by the arrow diagram is {(-3, 4), (-1, 5), (0, 7), (2, 2), (5, 7)}.
Option: C.
<u>Step-by-step explanation:</u>
A function is a relation in which each input value(domain) results in one output value(range). It is represented diagrammatically using the mapping method.
It shows how each element of domain and range are paired. That is like a flowchart it shows the input values marking its corresponding output value.
In the given diagram,
The values given in the left are domain and values given in the right are range.
Thus, -3 marks to 4, then can be written as (-3,4).
Similarly,
-1 marks 5 = (-1,5).
0 marks 7= (0,7).
2 marks 2= (2,2).
5 marks 7 =(5,7).
⇒ The complete points sequence is {(-3, 4), (-1, 5), (0, 7), (2, 2), (5, 7)}.
Answer:
95% two-sided confidence interval on the true mean breaking strength is (94.8cm, 99.2cm)
Step-by-step explanation:
Our sample size is 11.
The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So
.
Then, we need to subtract one by the confidence level 
and divide by 2. So:
Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 10 and 0.025 in the two-sided t-distribution table, we have 
Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So
Now, we multiply T and s
![M = Ts = 1.812*1.2060 = 2.19/tex]For the lower end of the interval, we subtract the sample mean by M. So the lower end of the interval here is[tex]L = 97 - 2.19 = 94.81 = 94.8](https://tex.z-dn.net/?f=M%20%3D%20Ts%20%3D%201.812%2A1.2060%20%3D%202.19%2Ftex%5D%3C%2Fp%3E%3Cp%3E%3Cstrong%3EFor%20the%20lower%20end%20of%20the%20interval%2C%20we%20subtract%20the%20sample%20mean%20by%20M.%3C%2Fstrong%3E%20So%20the%20lower%20end%20of%20the%20interval%20here%20is%3C%2Fp%3E%3Cp%3E%5Btex%5DL%20%3D%2097%20-%202.19%20%3D%2094.81%20%3D%2094.8)
cm
For the upper end of the interval, we add the sample mean and M. So the upper end of the interval here is
cm
So
95% two-sided confidence interval on the true mean breaking strength is (94.8cm, 99.2cm).

Answer:
Number 200 decreased by 10% (10 percent) of its value (percentage decrease) and calculated absolute change (actual difference). Answer: percentage decreased number = 180, absolute change (actual difference) = -20
