Recall that the square root of the negative one is "i" meaning that it is a complex number and not a real number.
Answer:
If the null hypothesis is true in a chi-square test, discrepancies between observed and expected frequencies will tend to be small enough to qualify as a common outcome.
Step-by-step explanation:
Here in this question, we want to state what will happen if the null hypothesis is true in a chi-square test.
If the null hypothesis is true in a chi-square test, discrepancies between observed and expected frequencies will tend to be small enough to qualify as a common outcome.
This is because at a higher level of discrepancies, there will be a strong evidence against the null. This means that it will be rare to find discrepancies if null was true.
In the question however, since the null is true, the discrepancies we will be expecting will thus be small and common.
F(x)= (x+4) ^{2} -13 is the answer

I have encountered this problem before. The figure gave out 3 chords, 2 of which are diameters, and 1 radius.
A chord is a line segment that joins any two points on a circle.
A diameter is the longest chord on a circle. It originates at one side of the circle, passes through the middle point of the circle, and end on another side of the circle.
The chords in the figure area: AD, BE, and DE. AD and BE are diameters, they pass through F.
Among the choices: A.) AD and B.) BE are the chords.
CF and DF are radii. They only end up in the middle point of the circle.
