40 times 24 times 154 divided by 2 will give you the answer.
Answer:
Step-by-step explanation:
Here X no of defective batteries is binomial with p = 1% = 0.01
q = 1-p=0.99
(Because each battery is independent and there are only two outcomes)
Prob that shipment is accepted is for n =36, 
=P(x=0,1,2)
= 
= 0.9944
The answer in this question is A, D and E, we might conclude if a random sample of 36 time interval between eruption has a mean longer that 104 minutes, I can conclude that the population means may be greater than 91 and the probability mean must be more that 91, since the probability is low and also the population mean is 91, and this is an example of a typical sampling result.
When there are one positive and one negative
We will define the following variables to solve the problem:
x = amount of round trips from 10 tons truck
y = amount of round trips from 12 tons truck
We write the system of equations:
x + y = 20
10x + 12y = 226
The solution to the system of equations is:
x = 7
y = 13
Answer:
10 tons truck makes 7 round trips
12 tons truck makes 13 round trips
