Answer:

\large\boxed{2.47\times10^{-3}=0.00247}

Step-by-step explanation:

<em>METHOD 1:</em>

\text{Use:}\ 10^{-n}=\dfrac{1}{10^n}\\\\2.47\times10^{-3}=2.47\times\dfrac{1}{10^3}=2.47\times\dfrac{1}{1000}=\dfrac{2.47}{1000}\\\\=\dfrac{2.47\times100}{1000\times100}=\dfrac{247}{100000}=0.00247

<em>METHOD 2:</em>

a\times10^n\\\\\text{If}\ n0\ \text{then move the comma n places to the right.}

\text{Therefore}\ 2.47\times10^{-3}=0\underbrace{.002}_{\leftarrow3}47

The primary purpose of the passage is to
Charra [1.4K]

The main purpose of the passage is to describe the purpose, methods, and results of an experiment. The correct option is B.

Given a passage shown in the attached pictures.

Option B is the best answer. The first paragraph of the passage identifies and describes "Texas squash vines" (line 1), but the main focus of the passage is introduced in the first sentence of the second paragraph. The remainder of the passage focuses on describing the purpose, process, and results of recent research conducted on these Texas squash vines.

Option A is incorrect because the passage doesn’t focus on the assumptions behind a theory but rather on the way in which that theory was tested. Option C is incorrect because the passage does not contain a lot of conflicting data; most of them support the idea that there may be too many scents for the Texas squash. Option D is incorrect because the passage explains the procedures used in a study were “’very labor intensive’” (line 58) but does not present them as particularly innovative.

Hence, the primary purpose from the given passage is to describe the aim, method, and results of an experiment.
