Answer:
A.
Negative reciprocal gives you the perpendicular slope so negative reciprocal of 1/2 is -2.
Then apply point-slope form.
B. The answer is x = 6.
The midpoint of JK is
The line that goes through JK is just a horizontal line because the y-coordinate does not change. So its perpendicular bisector is the vertical line that goes through the x-coordinate of the midpoint, that is,
.
Answer:
(a) Mean=74
(b) Median=70
(c) The best measure of center= Median.
Step-by-step explanation:
We have been given a data set of PSAT scores of Mrs. Turay's eight graders. We are asked to find mean and median of the given data set.
(a) Let us find mean of data set by dividing the sum of given scores by the number of students.
Therefore, the mean test score will be 74.
(b) Now let us find median of our given data set. We have been given that number of students is 10, therefore, our median will be the average of 5th and 6th term.
60, 62, 67, 69, 70, 70, 71, 75, 76, 120.
We can see that 5th term is 70 and 6th term is 70 as well.
Therefore, the median test scores will be 70.
(c) We can see that our data set has an outlier score as 120, which has increased the mean. Mean score is greater than median score. Since median is not affected by extreme value outliers, therefore, median will be the best measure of center for given test scores.

Answer:
The average rate of change in that interval is 1.99
Step-by-step explanation:
Here we have that the difference quotient for g(x) is:
Remember that for a general function f(x), the difference quotient is:
So if we look at the difference quotient for g(x), we can conclude that:
Also remember that the average rate of change in an interval (a, b) is just:
So here we want the average rate of change of g(x) in the interval from x = -2 to x = 1, this is:
The average rate of change in that interval is 1.99
