The roots, zeros, or solutions (they all means same thing) of an equation are when you graph that equation, x-intercepts are the real roots, zeros, or solutions.
Or set the y equal to zero which does the same job.
Two polygons are similar if their corresponding angles are congruent and their sides are in proportion.
The sides could be in a ration of 1:1 in which case the two hexagons have corresponding sides that are congruent, but they do not have to be. It could be the case that the sides of one are twice the length of the other so the ratio is 2:1. In this case the hexagons have the same shape but not the same size.
So the answer is this, the corresponding sides of similar hexagons may be congruent but do not have to be.
Answer: The hypothesis test is left-tailed test.
The parameter tested here is population mean.
Step-by-step explanation:
Given : The null and alternative hypotheses are as follows:
We can see that the parameter tested here is population mean.
Also, the type of test depends on the alternative hypothesis.
Since the alternative hypothesis is left-tailed so the hypothesis test is left-tailed test.
