Answer:
Step-by-step explanation:
Given that there is a sample statistic for a population. Population std deviation sigma is given as 5.75.
Margin of error = z critical value * std error
For standard error we must know the sample size n.
Std error =
Margin of error = Z critical * std error = for 95%
= for 99%
Z critical = 1.96 for 95% and 2.58 for 99%
Hence margin of error =

Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = .
In the equation you'd write that as r = which can be simplified to
.
You end up with and you simplify this by doing
, ending with the result of

Please find attached the required inverse of a function chart
Step-by-step explanation:
The inverse of a function is found by reversing the operations of the function
The inverse of the function f(x) = 2·x - 4 is found as follows;
x = 2·x - 4
x + 4 = 2·x
x = (x + 4)/2 = x/2 + 2
Therefore, the inverse of the function f(x) = 2·x - 4 is f(x) = x/2 + 2
The inverse function is plotted by generating data points as follows;
