Using z-scores, it is found that the unusual values are those that are less than 124.
---------------------------
The z-score of a measure X in a data-set with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations X is from the mean.
- Measures that are<u> more than 2 standard deviations from the mean</u> are unusual.
- Z < -2 means that the measure X is unusually low.
- Z > 2 means that the measure X is unusually high.
In this problem:
- Mean of 150, thus
. - Standard deviation of 13, thus
.
Unusual values are those that are less than 124.

Answer:
The vertical intercept is usually at which point the line of a graphs intersects with the y-axis.
For your information, the y-axis is the leftmost vertical line.

Answer:
a) 1/2
b) 1/2
Step-by-step explanation:
a) The average rate of change is the slope of the segment whose end points are the ends of the interval. On the interval [2, 8] the average rate of change is ...
m = (f(8) -f(2))/(8 -2) = (4 -1)/6 = 3/6 = 1/2
The average rate of change on the interval [2, 8] is 1/2.

b) In this context, "slope" and "average rate of change" mean the same thing. A line with the same slope will have a slope of 1/2.
The <em>correct answer</em> is:
D) Rotated perpendicular lines always remain perpendicular lines.
Explanation:
Perpendicular lines, by definition, meet at a 90° angle.
As long as both lines are rotated the same direction and the same angle, then the angle between the two lines will not change. They will continue to be perpendicular, no matter how many degrees or which direction they are rotated.
