Answer:
Part 1) 
Part 2)
Part 3) 
Part 4) 
Step-by-step explanation:
Part 1) Find the measure of arc AB
we know that
----> by central angle
we have

therefore

Part 2) Find the measure of arc ABC
we know that
The central angle of complete circle is equal to 360 degrees
so
Part 3) Find the measure of arc BAC
we know that
----> by angle addition postulate
we have
---> by central angle
---> by central angle
so

Part 4) Find the measure of arc ACB
we know that
The central angle of complete circle is equal to 360 degrees
so

substitute

Answer:
Solution: C) 7.815
Hint: From Chi-square table with (k-r-1)=(6-2-1) = 3 d.f the critical value = 7.8147
The statement that 99% of all confidence intervals with a 99% confidence level should contain the population parameter of interest is false.
A confidence interval (CI) is essentially a range of estimates for an unknown parameter in frequentist statistics. The most frequent confidence level is 95%, but other levels, such 90% or 99%, are infrequently used for generating confidence intervals.
The confidence level is a measurement of the proportion of long-term associated CIs that include the parameter's true value. This is closely related to the moment-based estimate approach.
In a straightforward illustration, when the population mean is the quantity that needs to be estimated, the sample mean is a straightforward estimate. The population variance can also be calculated using the sample variance. Using the sample mean and the true mean's probability.
Hence we can generally infer that the given statement is false.

Step-by-step explanation:
See whenever we have two variables like x and y.
And also we have given two equations in terms of x and y.
Example: ax + by = p and cx + dy = q
In order to get the solution, we need to find the value of x and y using the given two equations.
So here what we can do is:
Consider any one equation and get x or y from that equation.
i.e consider ax + by = p or x = 
Now plug value of x (or y) from the equation you have considered into the another equation.
i.e c(
)+dy = q
Now solve this equation to get y (or x).
and after that we can find the other variable.
