If women =  :evil:

 

then gays = 1/2  :evil:

<{POST_SNAPBACK}>

 

 

therefore 2 gays = :evil:

In accounting

Asset = Liabilities + Capital

 

In real life

Talent + Intelligence = Nothing

 

Determination + Talent + Intelligence = Success

Drake Equation

Is there a way to estimate the number of technologically advanced civilizations that might exist in our Galaxy? While working at the National Radio Astronomy Observatory in Green Bank, West Virginia, Dr. Frank Drake conceived a means to mathematically estimate the number of worlds that might harbor beings with technology sufficient to communicate across the vast gulfs of interstellar space. The Drake Equation, as it came to be known, was formulated in 1961 and is generally accepted by the scientific community.

N = R* fp ne fl fi fc L

 

where,

 

N = The number of communicative civilizations

R* = The rate of formation of suitable stars (stars such as our Sun)

fp = The fraction of those stars with planets. (Current evidence indicates that planetary systems may be common for stars like the Sun.)

ne = The number of Earth-like worlds per planetary system

fl = The fraction of those Earth-like planets where life actually develops

fi = The fraction of life sites where intelligence develops

fc = The fraction of communicative planets (those on which electromagnetic communications technology develops)

L = The "lifetime" of communicating civilizations

 

Frank Drake's own current solution to the Drake Equation estimates 10,000 communicative civilizations in the Milky Way. Dr. Drake, who serves on the SETI League's advisory board, has personally endorsed SETI's planned all-sky survey.

Pero how can a number is greater than infinite? non-terminating number na yun right?

1. Based on the following data on the relationship between job aptitude test (X) and job performance (Y) determine whether job aptitude test is a good predictor of performance or not at a level of significance of .05. Also Indicate how much of the variation in job performance is due to job aptitude; the regression equation; the intercept of the line; the slope of the line. What is the predicted result on the job performance test if the job aptitude of an individual is 70?

 

Job Apt 65 60 62 59 87 53 50 48 45 40

Job Per 90 95 82 87 80 75 60 69 60 72

1. The mean score of thousands of pupils who took a standardized test was 85 with a standard deviation of 8. A random sample of 50 pupils took the test and had a mean score of 83.20. Was this group’s performance lower than the ones in general at a =.05 level, critical value = 1.65?

A researcher wanted to know whether students recall more text information if they paraphrase what they read or if they just read the information again. 20 randomly selected students participated in the study. The following are the recall scores of the students after going through the experiment: Test hypothesis at a = .05

 

Reread 11, 12, 9, 14, 12, 14, 10, 11, 8, 11, 16, 22, 18, 15, 10, 8, 12, 15, 6, 11

 

Paraphrase15, 10, 13, 14, 14, 15, 14, 15, 9, 14, 17, 26, 15, 11, 11, 8, 14, 17, 8, 11

Five teachers taught Statistics to five sections of college students. The final grades of a random sample of 8 students per section are as follows: Do the five teachers have the same standards in giving grades? Test at a = .05?
