We have been given a table which lists some of the characteristics of the houses on Katrina’s street.
There are four different relation choices are given. now we have to identify which relationship describes a function.
We know that relations are written usually in ordered pairs (x,y) and a relation can be function only if x-value doesn't repeat.
So we just have to find which of the given ordered pair choices has no repeated x-value in the table.
We see that only "Appraised value" has no repeated value in the table. Hence 4th choice <u>(appraised value, property tax) </u>is the correct answer.

Answer:
The 95% CI for the difference of means is:
Step-by-step explanation:
<em>The question is incomplete:</em>
<em>"Find a 95% confidence interval on the difference of the towels mean absorbency produced by the two processes. Assumed that the standard deviations are estimated from the data. Round to two decimals places."</em>
Process 1:
- Sample size: 10
- Mean: 200
- S.D.: 15
Process 2:
- Sample size: 4
- Mean: 300
- S.D.: 50
The difference of the sample means is:
The standard deviation can be estimated as:
The degrees of freedom are:
The t-value for a 95% confidence interval and 12 degrees of freedom is t=±2.179.
Then, the confidence interval can be written as:
