Let the measure of the second angle be x.
The first angle has measure 3x - 34.
The sum of the measures is 180.
x + 3x - 34 = 180
4x - 34 = 180
4x = 214
x = 53.5
The second angle has measure 53.5 deg.
3x - 34 = 3 * 53.5 - 34 = 160.5 - 34 = 126.5
The measure of the first angle is 126.5 deg.
Answer: The measures are 126.5 deg and 53.5 deg.
Answer:
(47.3, 54.1)
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
That is z with a pvalue of , so Z = 1.96.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 50.7 - 3.4 = 47.3
The upper end of the interval is the sample mean added to M. So it is 50.7 + 3.4 = 54.1
The answer is (47.3, 54.1).
