Determine whether the sample is biased or unbiased. Explain.

You want to estimate the number of people in a town who think that a park needs to be remodeled. You survey every 10th person who enters the park.

Choices:

biased; The sample is not representative of the population because people who go to a park are more likely to think that the park needs to be remodeled.

biased; The sample is representative of the population and selected at random.

unbiased; The sample is representative of the population because people who go to a park are more likely to know the park's needs.

unbiased; The sample is representative of the population, selected at random, and large enough to provide accurate data.

Answer:

"unbiased; The sample is representative of the population, selected at random, and large enough to provide accurate data."

Step-by-step explanation:

Choosing the 10th person each time for a sample survey is unbiased as the chances of their opinion matching their opinion regarding the survey is highly unlikely. Hence, the data is accurate as everyone's opinion will differ throughout every 10th person.

Hope that helps!

Choose one kind of triangle to use for a tessellation: equilateral, isosceles, or
scalene.
Use technology or paper to create six or more congruent copies of your
chosen triangle and investigate how the shape tessellates.
Use your chosen triangle to create an artwork with tessellations. You can use
any sizes, colors, patterns, or art mediums. You can submit a scanned copy,
photo, screenshot, or snip of your artwork.
Provide the explanation of the math behind your tessellation that the gallery
will display next to your artwork.

Use the definition of your chosen triangle and what you know about
the interior angles of triangles to prove that any version or size of that
triangle will tessellate. (Hint: Study the interior angles where the
vertices meet in the tessellation.)
Include diagrams or other visual models to help explain your proof.
Think about how you could extend your work to prove that all triangles
tessellate, and share any theories you might have.
Your completed work of art will be submitted as your portfolio assessment. It must
