Answer:
you have described a "ray"
Step-by-step explanation:
A "ray" is a half-line: all the points on a line that are to one side of its terminal point. (The terminal point is included in the ray.)
Answer:
127°
Step-by-step explanation:
RQN and MNQ are the same
Answer:
-0.5 and negative one-half
-1/50 and -0.02
Step-by-step explanation:
-0.5 can be rewritten as -5/10. This can be simplified to -1/2 which is the same as negative one-half.
7/10 isn't equivalent to 11/20. If you multiply 7/10 by 2/2 to get the denominator of 20, it will become 14/20 not 11/20.
-1/50 in decimal form is -0.02 so -1/50 and -0.02 are equivalent.
0.15 and 1/5 aren't equivalent because 1/5 in decimal form is is 0.2, not 0.15.
Using the z-distribution, the 95% confidence interval of the population mean is: (17.5, 24.5).
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:

In which:
is the sample mean.
is the standard deviation for the population.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
For this problem, the other parameters are:

Hence the bounds of the interval are:


The interval is: (17.5, 24.5).
