Answer:

See below.

Step-by-step explanation:

All statements of congruent angles and congruent segments are correct.

A similarity statement can be written ...

Write a similarity statement ...

ABCD ~ HJKL

The reason written in the problem is incorrect. The polygons are similar, not congruent, so you cannot state that they are congruent as a reason for them to be similar.

This is the correct reason:

"The reason as why the two shapes are similar is that each angle A, B, C, D is congruent to each corresponding angle H, J, K, L, respectively, and the lengths of corresponding sides are proportional."

"A similarity ratio is a ratio that compares the <u>lengths</u> of the corresponding sides of two similar polygons. The ratio is written in the same order as the <u>two</u>

<u>polygons.</u>"

For the similarity ratio, we use two corresponding sides.

AB = 8; HJ = 12

AB/HJ = 8/12 = 2/3

The similarity ratio of ABCD to HJKL is 2/3.

Which is most likely the correlation coefficient for the set of data shown?
bearhunter [10]

Answer:

-.91

Step-by-step explanation:

I'm not 100% sure, because i don't have graphing calculator on me, but the correlation coefficient is how well the line of best fit goes with the data, and the data points on the graph look like they match the line. The closer the correlation coefficient is to 1 or -1, means that it has a strong correlation coefficient. It's negative because the slope of the line is negative. If you really want to make sure, you can plug it into a graphing calculator in STAT.

2.1x10^6<br> ______<br> 7x10^3<br><br> answer in standard form<br> ...................10^......
VMariaS [17]

Given:

The expression is:

\dfrac{2.1\times 10^6}{7\times 10^3}

To find:

The simplified form of the given expression in standard form.

Solution:

We have,

\dfrac{2.1\times 10^6}{7\times 10^3}

It can be written as:

\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21\times 10^5}{7\times 10^3}

\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21}{7}\times \dfrac{10^5}{10^3}

\dfrac{2.1\times 10^6}{7\times 10^3}=3\times 10^{5-3}        [\because \dfrac{a^m}{a^n}=a^{m-n}]

\dfrac{2.1\times 10^6}{7\times 10^3}=3\times 10^2

Therefore, the required value is 3\times 10^2.
