Answer:
(22.0297, 23.3703)
Step-by-step explanation:
Given that an economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in California.
Let X be per capita income (in thousands of dollars) for a major city in California.
Mean = 22.7
n = 183
Population std dev = 6.3
Since population std dev is known we can use Z critical value.
Std error = 
Z critical =1.44
Marginof error = ±1.44*0.4657=0.6706
Confidence interval 85%

The values of the function if the function f(x) is reflected over y-axis is g(x) = 10/21x
<h3>Reflection of coordinates</h3>
Reflection is a transformation technique that changes the position of an object on an xy-plane.
If the function f(x) is reflected over y-axis, the resulting function is y = f(-x). Given the following function;
f(x) = -2/7(5/3)x
This can also be written as;
f(x) = -10/21 x
Replace x as -x
f(-x) = -10/21(-x)
f(-x) = g(x) = 10/21x
Hence the values of the function if the function f(x) is reflected over y-axis is g(x) = 10/21x
