Answer:
Step-by-step explanation:
- Measure of angle J K H + measure of angle J K L = 180 degrees
True.
- Measure of angle J K L + measure of angle J L K + measure of angle K J L = 180 degrees
True. The sum of all interior angles = 180
- Measure of angle J K H = measure of angle J L K =

Step-by-step explanation:
Answer:
The minimum sample size required to ensure that the estimate has an error of at most 0.14 at the 95% level of confidence is n=567.
Step-by-step explanation:
We have to calculate the minimum sample size n needed to have a margin of error below 0.14.
The critical value of z for a 95% confidence interval is z=1.96.
To do that, we use the margin of error formula in function of n:

The minimum sample size to have this margin of error is n = 567.
<1=97°
steps:
<1+83=180 co interior angle
<1=180-83=97°
