What kind of association is this, negative or positive?​
erik [133]

Answer:

negative association

Step-by-step explanation:

This diagram is a scatter plot which represents a set of data.  Data on a scatter plot can fit one of three descriptions:  positive (increasing), negative (decreasing) or no association (points do not form any kind of line).  Given this data and the line of best fit, or the line that pass through the majority of the points, it is a decreasing line.  Since the line goes downhill, it is a negative association.

I dont understand how to do this
Airida [17]

The statement EF=2.GF (Option A) and the statement

\frac{\sqrt{3} }{2} .EF=GE (Option C) are true for the ΔEFG.

<h3>What are trigonometric ratios?</h3>

The six trigonometric ratios of a right-angle triangle are Sin, Cos, Tan, Cosec, Sec and Cot. Trigonometric ratios are used to measure the sides of the right triangle.

Given that in ΔEFG, m∠E=30°, m∠F=60° and m∠G=90°.

Wow, sin 30°=\frac{GF}{EF}

⇒\frac{1}{2} =\frac{GF}{EF}

⇒EF=2.GF

and sin 60°=\frac{GE}{EF}

⇒\frac{\sqrt{3} }{2} =\frac{GE}{EF}

⇒\frac{\sqrt{3} }{2} .EF=GE

Therefore, the statement EF=2.GF (Option A) and the statement \frac{\sqrt{3} }{2} .EF=GE (Option C) are true for the ΔEFG.
