Answer:
1/3 =5x-2
3(1/3)=3(5x-2)
1=15x-6
7=15x
x=7/15 (7/15 , 1/3)
Step-by-step explanation:
Answer:
B. Married, widowed, or divorced men have high income jobs. A high income job tends to make an individual more dedicated. This dedication leads a man to get married.
Step-by-step explanation:
A lurking variable is one that is not measured in the given study but it will affect the relationship between the explanatory and response variables.
Now, in this case, we see that divorced or widowed men, are said to earn quite a little more than men that are of the same age who have never been married.
Now, we are told it does not imply that a man can raise his income by getting married.
This means that majority who have high income tend to consider getting married.
Thus, we can infer that having a high income job leads to a man being more dedicated and this leads him to getting married.
Answer:
Probability that an ear of corn selected at random will contain no borers is 0.4966.
Step-by-step explanation:
We are given that the distribution of the number of borers per ear approximated the Poisson distribution. The farmer counted 3,500 borers in the 5,000 ears.
Let X = <u><em>Number of borers per ear</em></u>
The probability distribution of the Poisson distribution is given by;
where, = parameter of this distribution and in our question it is proportion of bores in the total ears = = 0.7
SO, X ~ Poisson( = 0.7)
Now, probability that an ear of corn selected at random will contain no borers is given by = P(X = 0)
P(X = 0) =
= = <u>0.4966</u>
Hence, the required probability is 0.4966.
