Answer: 0.34
Step-by-step explanation:
Given : The proportion of items in a shipment are known to be defective : p=0.08
Number of items selected = 5
By using binomial probability distribution formula, the probability of getting success in x trials is given by :-
Now, the probability that at least one defective item will be observed in this sample will be :-
Hence, the probability that at least one defective item will be observed in this sample is 0.34
Answer: 4.2*w + 7*x + 5.4
Step-by-step explanation:
Here we need to remember how the product of different signs works, here is the rule:
(+)*(+) = (+)
(+)*(-) = (-)
(-)*(+) = (-)
(-)*(-) = (+)
Now we want to distribute the negative sign in the equation:
"-(-4.2w-7x-5.4)"
We can write this as:
-(-4.2w-7x-5.4) = (-1)*(-4.2w-7x-5.4)
Now we can distribute the "-1"
Then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4)
We have 3 cases where we need to use the "(-)*(-) = (+)" rule, then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4) = 4.2*w + 7*x + 5.4
