Answer:
a.The classification error rate for records that are truly fraudulent: By increasing the cutoff value, the non-fraudulent records will go down and this increases the error rate.
Also, if the cutoff value is down, the fraudulent records will increase and this lowers the error rate
.b.The classification error rate for records that are truly non-fraudulent: By moving up the cutoff value, the fraudulent records will go down and this decreases the error rate.
Also, if the cutoff value is down, the non-fraudulent records will go down and this increases the error rate.
Answer:
$ 1.50 x 25= 37.50
Step-by-step explanation:
Subtract that from $ 87.50 you get remainder $ 50.00.
Therefore grocer paid $ 50.00 for 25 bags. $ 50.00 divided by 25= $ 2.00 per bag.
Answer:
x = -2
Step-by-step explanation:
The line x = - 5 means it is a straight vertical line that has no slope. This means that the slope is undefined.
Now, for this line to be parallel to the line passing through point P(−2, 6), it means the line will be a vertical line too with the equation of form (x = a).
Thus, the equation of the line is x = -2
Answer:
Where is the graph to use
The slope of XY is the same as the slope of AB because XY is parallel to AB. Parallel lines have the same slope.
