A.) Similar? <u>  </u><u>YES  </u>

Why or why not? <u>  It is similar because as your can see in the picture above, it shows a large triangle and a small triangle. On the smaller triangle, the corner "G" has a degree of 67. On the larger triangle, the corner "P" has the same degree as the smaller one, therefore all the other corners have the same degree making the missing degree for "R" 34 degrees, and the missing "C" 79 degrees.  </u>

If so, <em>*</em>similarity statement and scale factor: SF: <u>  1.5  </u>

*I didn't know what they meant by similarity statement

B.) Similar? <u>  NO  </u>

Why or why not? <u>  The triangles are two totally different shapes, with totally different degree angles, making it totally different  </u>

If so, <em>*</em>similarity statement and scale factor: SF: <u>  2  </u>

*I didn't know what they meant by similarity statement

C.) Similar? <u>  NO  </u>

Why or why not? <u>  The triangles are two totally different shapes, with totally different degree angles, making it totally different  </u>

If so, <em>*</em>similarity statement and scale factor: SF: <u>  1.2  </u>

*I didn't know what they meant by similarity statement

D.) Similar? <u>  YES  </u>

Why or why not? <u>  They are the same shape; just with one enlarged and one decreased in size. They both have the same angle degree and everything else similar but the size of the shape.  </u>

If so, <em>*</em>similarity statement and scale factor: SF: <u>  2  </u>

*I didn't know what they meant by similarity statement

**To find the scale factor you would have to divide the big number, to the smaller number... Like for figure D, the base of the BIG triangle is 56, and the small triangle is 28. 56 ÷ 28 = 2 Making <u>2</u> the SF (Scale Factor)

Answer:

(d) WEAK NEGATIVE ASSOCIATION.

Step-by-step explanation:

Pearson correlation (r) is defined as a factor which measures the linear dependence between two variables (x and y). It's also known as a parametric correlation.

Here, r = -0.19

Now, as r is NEGATIVE.

⇒ As the value of x increases , value of y decreases.

⇒There is a  NEGATIVE ASSOCIATION.

Now as the value of r is between 0 and ( -1). So the factor of variation is very small.

Hence, it is WEAK NEGATIVE ASSOCIATION.
