The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Show all work to receive full credit

Alla [95]

Answer:

The answer is below

Step-by-step explanation:

The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?

Solution:

a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:

Circumference = 2π × radius; but diameter = 2 × radius. Hence:

Circumference = π * diameter.

Given that diameter of the tire = 2.5 ft:

Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft

b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.

1 mile = 5280 ft

The number of rotation required to cover 1 mile (5280 ft) is:

number of rotation = $\frac{5280\ ft}{7.85\ ft\ per\ rotation}=672\ rotations\\\\\\$

In an effort to learn more about the wild lemur population in Madagascar, a researcher wants to collect a sample. Which statemen

steposvetlana [31]

A reseacher wants to collect a sample to learn more about the wild lemur population in Madagascar. According to this, the true statement is the reseacher can assign each lemur a number and then use a systematic sampling (option A).

Systematic sampling is a form of sampling characterized by choosing the sample at random. According to the above, random sampling is the best option for the researcher.

It is not easy to study the entire population of lemurs in Madagascar, therefore systematic sampling is ideal. In this way, the researcher can sample a few lemurs and using this probability method can draw conclusions.

According to the above, the correct answer is A. because it presents information corresponding to the situation presented.
