Answer:
A. 0.22
B. 0.18
C. 0.25
D. 0.244
Step-by-step explanation:
S = {51 to 100} = 50
The sample space S contains values from 51 to 100 which is a total of 50 different values.
A.
Probability of A (lies between the values of 90 to 100 = 11).
11/50 = 0.22
B.
For a student to fail the course, his course has to be less than 60 = from 51 to 59. A total of 9 values.
9/50 = 0.18
C.
For student to get c, (70 to 79) a total of 10 values: 10/50 = 0.20
P(student did not get C) = 1-0.20 = 0.80
To get B, ( 80 to 89)
10/50 = 0.20
Probability that a student who is known not to have a c grade has a b grade = 0.20/0.80 = 0.25
D.
Probability of passing lies between 60 to 100 = 41 scores
41/50 = 0.82
Probability of student who passed having a B = 0.20/0.82 = 0.244
Answer:
The rangers
Step-by-step explanation:
Their number of wins didn't go up. In fact their wins decreased the most.
C < 5
there will be an open circle on 5....it is open because there is no equal sign in the problem.....the shading will be to the left....because less then is shaded to the left
Answer:
Step-by-step explanation:
points that lie on an axis do not lie in any quadrant.
So point A lies in the positive x-axis
The origin (0,0) does't lie on any quadrant.
Origin is the point that lies on both x-axis and y-axis
Answer:
The Second Method
Step-by-step explanation:
APE (Absolute Percentage Error) = absolute difference / actual * 100
APE for First method = 61.93
APE for second method = 54.97
MAPE (Mean absolute Percentage error) = Sum of absolute Percentage error/ Number of observations. ( i.e., 4)
Then,
MAPE for the first method = 61.93 / 4 = 15.482
MAPE for the second method = 54.97 / 4 = 13.472
So, MAPE for second method is less than the MAPE for first method.
