Given that line PN is a perpendcular bisector of line AB, then angles APN and BPN are equal to 90 degrees each.
Also, given that line PN is an angle bisector to angle CPD and angle CPD measures x, then the measure of angle DPN is

.
Thus, the measure of angle DPB = angle BPN - angle DPN

Therefore,
Answer:
A
Step-by-step explanation:
The y intercept is simply where the line intercepts the y intercept in this case it's (0,2)
An easy way to slope is rise over run.
Simply find a point on the graph and count how many times you have to go up,down,left, or right to get to the next point
in this case it's 3
Since the slope is going down we know it will be negative.
Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
