Answer:
The answer is -40 and -20
Answer:
0.3830,0.6170
Step-by-step explanation:
Given that a process for manufacturing an electronic component yields items of which 1% are defective.
n =100 and p = 0.01
Here X no of defectives is binomial since independence and two outcomes.
Approximation to normal would be
X is N(![100(0.01) , \sqrt{100(0.01)(0.99)} )](https://tex.z-dn.net/?f=100%280.01%29%20%2C%20%5Csqrt%7B100%280.01%29%280.99%29%7D%20%29)
X is N(1,0.995)
a) the probability that the process continues given the sampling plan described
= ![P(X=0)](https://tex.z-dn.net/?f=P%28X%3D0%29)
(with continuity correction)
=![P(|x|](https://tex.z-dn.net/?f=P%28%7Cx%7C%3C0.5%29%5C%5C%3DP%28%7CZ%7C%3C0.50%29%5C%5C%3D%202%280.1915%29%5C%5C%3D0.3830)
b) the probability that the process continues even if the process has gone bad (i.e., if the frequency of defective components has shifted to 5.0% defective)
1-0.3830
=0.6170
Answer:
B. This relationship represents a function because no length of ribbon has more than one price.
Step-by-step explanation:
A relation is considered as a function when there is exactly just one possible range value that any of the domain value can give. In order words, each domain value of a function cannot have more than one range value.
In the given table of values representing the length and price of ribbon, the domain includes all the set of lengths of the ribbon while the range is the set of the corresponding prices the lengths can cost.
Thus, each length given has exactly just one price. No particular length has more than one price. Therefore, we can consider this as a function.
Answer:
x=-2
Step-by-step explanation:
-2x=4
Divide each side by -2
-2x/-2=4/-2
x = -2
