What happens if the correlation coefficient equals 0?

1 answer:

3 0

The correlation coefficient represents the strength of a relationship of two sets of data relative to how linear they are. A correlation coefficient of r = 1 would indicate that the relationship was perfectly linear, a correlation coefficient of 0 would mean that they have absolutely no relationship linearly, and are completely dispersed. Hope that makes sense! :) :D

Here's what I got.

Column C, starting from the top and going down: $12.33, $13.00, $10.50, $10.00, $6.00, $8.00, $4.25, $10.50, $11.50, and $8.50

Column F, Starting from the top and going down: $4,650, $4,650, $4,650, $4,600, $4,600, $4,600, $5,000, $5,000, $4,625, and $4,625.

I don't really understand column G yet, so that's all I have. Hope it helped a little bit.

Which equation has infinitely many solutions?

raketka [301]

Answer:

Step-by-step explanation:

5.1 + 2y + 1.2 = -2 + 2y + 8.3 ( subtract 2y on each side)

5.1 + 1.2 = -2 + 8.3 ( collect like terms)

6.3 = 6.3

If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.

Triangle A B C is shown. Angle A B C is a right angle. An altitude is drawn from point B to point D on side A C to form a right

Anika [276]

Answer:

C. - X = 5 units

Step-by-step explanation:

We need to solve for x from the given figure.

In ΔADB and ΔCDB

∠ABD=∠BCD (Corresponding angle of two right triangle)

∠ADB=∠CDB (Each 90°)

∴ ΔADB ≈ ΔCDB By AA similarity

If two triangles are similar then ratio of their corresponding height are same.

Substitute the value of side into the expression

Cross multiply and solve for x

x can't be negative because side of triangle is positive.

Hence, The value of x is 5 units.
