When a scatter plot shows a positive association means that there is a linear correlation with a positive slope between the two variables. This correlation can be weaker or stronger (depending on the value of the correlation).
If there is a linear correlation between the two variables, the relation is then a direct proportionality (with slope positive or negative).
Hence, it is always true that <span>a scatter plot that shows a positive association suggests that the relationship is proportional.</span>
Answer:
b is the correct answer for apex users
Answer:
the ratio would be 9:4 because you just add
Step-by-step explanation:
just add the rstio
Since the entire length is 36 you subtract what lengths you know first 7 and 1 (36-7-1=28) since there are 7 x’s left over you just divide 28/7 and you get x = 4
Answer:
The two triangles are related by <u> hypotenuse leg </u>
so the triangles are <u> congruent </u>
======================================================
Explanation:
The square markers indicate we have 90 degree angles. This means the two triangles are right triangles.
The tickmarks tell us which sides correspond and are the same length. The double tickmarked sides are the hypotenuses of each triangle. They are the same length because of the matching tickmarks. The same can be said about the legs marked with single tickmarks.
Based on those tickmarks, and the fact we have right triangles, we can use the <u>hypotenuse leg theorem</u> to prove the <u>triangles are congruent</u>.
The hypotenuse leg theorem only works for right triangles.
Since "hypotenuse leg" is used quite often in geometry, it is abbreviated to "HL".
