Answer:
I think that the answer to this question is the third one . I mean 29 .
Answer:


Step-by-step explanation:
From the question we are told that
Number of math tests n=15
standard deviation 1 
standard deviation 1 
Generally given the two tailed test the null hypothesis is given as

Generally given the two tailed test the null hypothesis is given as

Option B is correct. <em>Point F</em><em> is the </em><em>only point </em><em>according to the option given</em>
A point is defined as an exact location with no size, length, or even width.
From the diagram shown, we have points, plane, and line segments.
- The only plane that we have is plane R making option C incorrect.
- A line is defined as a straight figure connected by two points. From the diagram, the line segments that we have are AN, BN, and AB falsifying options A and D.
The points are C, D, E, and F. Hence the correct option is B.<em> Point F</em><em> is the </em><em>only point </em><em>according to the option given</em>

In math, an isometry is a congruent transformation in which the distance (or length) and the angle is preserved or remains the same even after the transformation.
The transformation can be translation, rotation, reflection, etc.
Let us not use this definition of isometry to answer our question, one at a time.
(I) In here, as we can see the distances 10 and 5 and the angle 43 degrees has been preserved. So, <u>this is an isometry.</u>
(II) In here, distances have been halved, so this is<u> not an isometry</u>, even though the angles have been preserved.
(III) In here, the corresponding distances and the angles have been preserved. So, <u>this is an isometry.</u>
