The hypothesis are 
Step-by-step explanation:
Consider the provided information.
Testing 500 right-handed participants on the reaction time of their left and right hands to determine if there is evidence for the claim that the right hand reacts faster than the left.
Yes, The above analysis involves a statistical test.
Where claim is right hand reacts faster than the left hand.
If right hand reacts faster that means the reaction time of right hand should be smaller than the reaction time of left hand.
Let 
to be the average reaction time of their right hands for the right-handed participants and 
to be the average reaction time of their left hands.
Therefore, the hypothesis are
Answer:
31
Step-by-step explanation:
Answer:
The value of k is -2
Step-by-step explanation:
The cut point with the y axis for both graphs occurs when x = 0
We then have:
For f (x):
The cut point for the y axis is:
For g (x):
The cut point with the y axis is:
The value of k is given by the vertical displacement of graph k units.
We then have:
Let's clear k:

Answer:
(c) ∠ECF and ∠BCF
Step-by-step explanation:
Complementary angles total 90°. Here, 90° angle BCE is divided by ray CF into two complementary angles. They necessarily have a total of 90°.
∠ECF and ∠BCF
