since there is no x value the equation can not be solved any further.

Answer:
The x-intercepts of a function are found where the graph of a function crosses the x-axis on a pair of Cartesian coordinate axes. How to Find the X-intercepts of a Function The x-intercepts of a function f (x) is found by finding the values of x which make f (x) = 0. Write f (x) = 0, and solve for x to find the x-intercepts of a function.
Step-by-step explanation:
find the x-intercepts ans you will be able to answer the rest of the question then fill in the blanks
hope this helps :)

Answer:
And the 90% confidence interval would be between [566.80 and 579.20]
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
s=22 represent the sample standard deviation
n=36 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.90 or 90%, the significance would be and , and the critical value for this case would be
And replacing we got:
And the 90% confidence interval would be between [566.8033 and 579.1967]
