Step-by-step explanation:
The vertex is (-1.5, -6.75). So the x-coordinate is -1.5. Hope this helps and if so please leave a good rating and thanks. I really appreciate it. Have a nice day!
Answer: The maximum error = $105.76.
Step-by-step explanation:
Formula to find the maximum error:

, where n= sample size.
= Population standard deviation
z*= Critical value(two-tailed).
As per given , we have

n= 35
For 98% confidence , the significance level = 
By z-table , the critical value (two -tailed) =
Now , the maximum error = 


Hence, With 98% confidence level , the maximum error = $105.76.
