Answer:
K' = (8,-4) L' = (4,-7) M' = (1,-2)
Step-by-step explanation:
Simply take the x coordinates and the y coordinates and flip them.
For example, if you have A (2, 4) reflected across y=x, A' would be (4,2).
x = 6 , 5
, − 3 IS THE ANSWER
For this case, what you should see is which lines contain point O.
We have then that the lines that contain this point are:
EC
AD
BO
We note that three lines contain point O.
Therefore, three lines intersect at the same point.

Using the t-distribution to build the 99% confidence interval, it is found that:
- The margin of error is of 3.64.
- The 99% confidence interval for the population mean is (19.36, 26.64).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:

In which:
is the sample mean.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 21 - 1 = 20 df, is t = 2.086.
The other parameters are given as follows:

The margin of error is given by:

Hence the bounds of the interval are:


The 99% confidence interval for the population mean is (19.36, 26.64).

Answer:
B,C,E
Step-by-step explanation:
did the assignment on Edge 2020
B. draw an open circle at 100
C. shade all numbers to the right of 100
E. 150 is shaded, so substitute 150 in for the variable to check the graph of the solution
