1. Consider square ABCD. You know that
then
2. Consider traiangle AED. F is mipoint of AE and G is midpoint of DE, then FG is midline of triangle AED. This means that
3. Consider trapezoid BFGC. Its area is
where h is the height of trapezoid and is equal to half of AB. Thus,
4.
5. Note that angles EGC and CGD are supplementary and
Then
Answer:
Answer:
Step-by-step explanation:
We have these following probabilities:
40% probability that the first file is corrupted. So 60% probability that the first file is not corrupted.
30% probability that the second file is corrupted. So 70% probability that the second file is not corrupted.
Probability mass function
Probability of each outcome(0, 1 and 2 files corrupted).
No files corrupted:
60% probability that the first file is not corrupted.
70% probability that the second file is not corrupted.
So
One file corrupted:
First one corrupted, second no.
40% probability that the first file is corrupted.
70% probability that the second file is not corrupted.
First one ok, second one corrupted.
60% probability that the first file is not corrupted.
30% probability that the second file is corrupted.
Two files corrupted:
40% probability that the first file is corrupted.
30% probability that the second file is corrupted.
Charges per load = $5.25
Total money = $31.50
As the situation says that charges are 5.25 and one has a total money of 31.50 so lets suppose the total load one has be 'w'
so equation becomes:
solving it we get,
So, option C is the correct answer.
