Answer:
C) {6+√43, 6-√43}
Step-by-step explanation:
Applying,
x = [-b±√(b²-4ac)]/2a.................... Equation 1
From the question,
Given: a = 1, b = -12, c = 7
Substitute these values into equation 1
x = [-(-12)±√(-12²+4×1×7)]/2×1
x = [12±√(144+28)]/2
x = [12±√172]/2
either,
x = (12-√172)/2
x = (12-2√43)2
x = (6+√43)
or
x = (12+√172)/2
x = (12+2√43)/2
x = (6+√43)
Hence,
The right answer is C). {6+√43, 6-√43}
The correct answer for the completion exercise shown above is: "Goodness of fit test".
Therefore, the complete sentence is shown below: "A goodness of fit test is used to test the hypothesis that an observed frequency distribution fits (or conforms to) some claimed distribution".
The goodness of fit test, which is also known as "GOF" is usefull to know how well the selected distribution fits to the data. The result are usually presented in tables called "Interactive tables".
