if there are 26 students in each third-grade class and 3 third grade classes in the school, how many students will attend an ass
2 answers:
Answer: There are 74 students of third grade attend an assembly .
Step-by-step explanation:
The number of students in third grade classes = 26
The number of third classes in the school = 3
Therefore, the total number of students of third grade in the school =
Now, it 4 students are absent then the number of third grade students in the school =
Hence, there are 74 students of third grade attend an assembly .

Answer:
0.335
Step-by-step explanation:
1. There is a 30 percent chance of a flight being delayed because of icy weather ,then the probability of being delayed is 0.3 and of being not delayed is 0.7.
2. If a flight is delayed because of icy weather, there is a 10 percent chance the flight will also be delayed because of a mechanical problem, then the probability of being delayed is 0.1 and the probabilty of not being delayed is 0.9.
3. If a flight is not delayed because of icy weather, there is a 5 percent chance that it will be delayed because of a mechanical problem (MP), then the probability of being delayed is 0.05 and the probabilty of not being delayed is 0.95. (See attached probability tree)
Delayed of icy weather - 0.3
Delayed of MP when weather is not icy - 0.7·0.05=0.035
Now, if one flight is selected at random from the airport in January, the probability that the flight selected will have at least one of the two types of delays is
0.3+0.035=0.335
Answer:
Step-by-step explanation:
Given
Required
Represent as an equation;
Expand the above
<em>Recall that b = $10 ----given</em>
becomes
Give the equation 9m = 10n
Dividing both sides by 9n, we have
Therefore, the <span>proportion that results in the equation 9m = 10n is
</span>
Dividing both sides by 9n, we have
Therefore, the <span>proportion that results in the equation 9m = 10n is
