Answer:
800. Here's why:
Step-by-step explanation:
This indicats that 440 students make up 55% of the 6th grade population. We can write this as
55/440.
We also know that 'x' total students make up 100% of the 6th-grade population, so we can write this as
100/x.
55/440 must be equal to 100/x. When cross multiplied, it becomes 50x=44000. If we divided each side by 50, we'll find that x=880. Therefore, there are 800 6th graders

Answer:
1. 0.99993108.
2. 6 components.
Step-by-step explanation:
(a) Probability of 1 component failing = 0.041
So the probability of the whole system failing = 0.041^3.
Therefore the probability of not failing
= 1 - 0.041^3 = 0.99993108.
(b).
Try 5 components:
1 - 0.041^5 = 0.99999988
6:
1 - 0.041^6 = 0.9999999952.
So the answer is 6 components.
