Answer:Jarvis's class average is 75
Step-by-step explanation:
The total possible average score for the math course is 100
a) If the teacher rates homework at 10%, it means that the total possible score for homework
is 10/100 × 100 = 10
If his homework average is 93, then his score would be
(93×10)/100 = 9.3
b) If the teacher rates quizzes at 30%, it means that the total possible score for quizzes
is 30/100 × 100 = 30
If his quiz average is 82, then his score would be
(82×30)/100 = 24.6
c) If the teacher rates test at 40%, it means that the total possible score for quizzes
is 40/100 × 100 = 40
If his quiz average is 72, then his score would be
(72×40)/100 = 28.8
d) If the teacher rates final exam at 20%, it means that the total possible score for quizzes
is 20/100 × 100 = 20
If his final exam is 60, then his score would be
(60×20)/100 = 12
Jarvis's class average would be
9.3 + 24.6 + 28.8 + 12 = 74.7
Approximately 75

Answer:
0.0788
Step-by-step explanation:
In this case the final probability will be the sum of the probability of when there are 67 more reserves when there are 68.
That is to say:
P (f) = P (x = 67) + P (x = 68)
n = 68; p = 0.94
Now we calculate each one:
P (x) = nCx * (p ^ x) * [(1 - p) ^ (n-x)]
nCx = n! / (x! * (n - x)!)
Knowing the formula, we replace:
P (67) = 68C67 * (0.94 ^ 67) * [(1 - 0.94) ^ (68-67)]
nCx = 68! / (67! * (68 - 67)!) = 68! / 67! = 68
P (67) = 68 * (0.0158) * (0.06) = 0.064
Now for x = 68
P (68) = 68C68 * (0.94 ^ 68) * [(0.0641 - 0.94) ^ (68-68)]
nCx = 68! / (68! * (68 - 68)!) = 1
P (68) = 1 * (0.0148) * (1) = 0.0148
Then replacing in the main formula:
P (f) = P (x = 67) + P (x = 68)
P (f) = 0.064 + 0.0148
P (f) = 0.0788
