Answer:
Step-by-step explanation:
given that a batch of 140 semiconductor chips is inspected by choosing a sample of 5 chips without replacement.
10 chips do not conform to customer requirements.
i.e. out of 140 chips 10 are defective and 130 are good
a) 5 chips can be selected form 140 chips in 140C5 ways
= 416965528
b) For containing exactly one non conforming chip we have one selected from 10 and other 4 selected from 130
No of ways = 
c) For atleast one nonconforming chip we can calculate as total - no non conforming
i.e. 
Answer:
Step-by-step explanation:
a. H0: μ ≤ 104 Ha: μ > 104
Assuming the data leads to the rejection of the null hypothesis, we would conclude that there is no sufficient statistical evidence to prove that the cost of electricity for an efficient home in a particular neighborhood of Cincinnati, Ohio, was $104 per month.
b. The type error in this situation would be rejecting the null hypothesis when it is actually true. Rejecting the fact that the cost of electricity for an efficient home in a particular neighborhood of Cincinnati, Ohio, was $104 per month when it was actually true.
c. Type II error in this case would be failing to reject the null when it is false. Failing to reject the fact that the cost of electricity for an efficient home in a particular neighborhood of Cincinnati, Ohio, was $104 per month when it is actually not true.
The consequences for these errors might be disastrous including sueing of the accuser party etc.
I'm not sure what grid you're referring to, but in the factorized form this equation is 4(4x^2 + 12xy +9y).

C
Step-by-step explanation:
The change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
Given that a weather balloon is descending from the atmosphere, and its altitude changes by -6 meters every second, to determine what is the change in altitude after 135 seconds the following calculation must be performed:
- Amount of time x change per second = total change
- 135 x (-6) = X
- -810 = X
Thus, the change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
