Part B: B) Mish is growing faster by one pound
Step-by-step explanation:
Answer:
A. Both rotational and reflectional.
Step-by-step explanation:
We have been given an image of a regular polygon. We are asked to determine type(s) of symmetry for our given polygon.
Upon looking at our given polygon, we can see that it is a pentagon.
We know that a regular pentagon has five equal sides and five lines of symmetry.
We can see that each line of symmetry divides pentagon into two mirror images, therefore, our given pentagon has reflectional symmetry.
We know that the regular polygon has a rotational symmetry. We can find rotational symmetry of a regular polygon by multiplying 360 degrees by number of sides.


Therefore, a regular pentagon has rotational symmetry.
Bias refers to scenarios which might affect the ability of a statistical experiment to generalize, hence affecting the validity of research. Non-response bias occurs when majority of subjects <em>fail to respond during a survey</em>. Hence, a likely scenario is ; <em>surveys were mailed to 500 people, and 200 of the surveys were completed and </em><em>returned</em><em>.</em><em> </em>
- Non - response bias has to do with a situation whereby a large percentage of the selected samples from a population do not respond or fail to participate in the experiment or survey.
- If 200 surveys were returned, then 300 of the sample participants did not respond. Which means <em>60% of the sample are non-responsive</em>.
Therefore, a scenario where <em>surveys were mailed to 500 people, and 200 of the surveys were completed and </em><em>returned</em><em> </em>exemplifies a non - response bias.
