Answer:
127 degrees
Step-by-step explanation:
Because the total sum of all the angle in a hexagon is 720 degrees so in this case, x would be:
720 - 112 - 133 - 128 - 100 - 120 = 127 degrees
x would = 127 degrees

Answer:
The 99% confidence interval for the proportion of all students at this school who have their names written on their graphing calculators is (0.4652, 0.8148).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
A random sample of 50 students is selected, and of the students questioned, 32 had their names written on their graphing calculators.
This means that
99% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 99% confidence interval for the proportion of all students at this school who have their names written on their graphing calculators is (0.4652, 0.8148).
