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:
22.5 deg
Step-by-step explanation:
It would be helpful to draw out a diagram but I'll explain in words.
We start at 0, ground level.
Then up a 100 metre hill, so now we are at 100m.
It plunges down 72, so we take away 72 to get 28m.
Then it takes them back up 48m, so we add 48 to get 76m.
That means that they are 76m above from where they started, ground level.
Hope I helped!
99,999,999 + (-4) is basically 99,999,999 - 4
99,999,999 - 4 = 99,999,995
Answer:
16. 30 * (30+12)/4*(L)*20
17. Volume = 6300 * Length of rectangular prism
Step-by-step explanation:
The width of a rectangular prism is <u>30 cm</u>. This is <u>12 more than one-fourth of the length</u>. Find the volume of the prism, given the <u>height is 20 cm</u>.
Let L = length of rectangular prisim W = width and H = height
16.
Volume of a rectangular prism is width * length * height
30 * (30+12)/4*(L)*20
17.
= 30 * (30+12)1/4(L)*20
= 30 * (42/4)*L * 20
= 600 * 10.5 * L
= 6300 * L
Volume = 6300 * Length of rectangular prism
