Answer-

- 0.9 represents the strongest correlation

Arrangement

Correlation coefficient-

Correlation coefficient measuring a linear relationship between the two variables shows the measure of variation of one variable represented by the other variable.

The coefficient of correlation dependably lies between – 1 and 1, including both the constraining qualities, for example

The more closer its outright incentive to 1, the stronger the relationship is.

In the event that r is - ve, at that point the relationship is negative (i.e in the event that one increases, at that point the other must decrease)

On the off chance that r is +ve, at that point the relationship is certain (i.e on the off chance that one increases, at that point the other must increase)

As, in the event of - 0.9, its supreme esteem 0.9 is more closer to 1, so it is the strongest correlation (strong-negative correlation)

Answer:

d

0.9

The value of a correlation coefficient ranges between -1 and 1.

The greater the absolute value of the Pearson product-moment correlation coefficient, the stronger the linearrelationship.

The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.

The weakest linear relationship is indicated by a correlation coefficient equal to 0.

A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.

A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.

hope it helps.

Round your answer to the nearest tenth.

Kruka [31]

Answer:

The value of MB = 8.4

Step-by-step explanation:

We know that the point of intersection of the Medians of a triangle is called the centroid of a triangle.

Thus,

For the given triangle ΔJKL,

The point M is the centroid of the triangle.

We also know that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.

Also, each Median is split into two parts such that the longer part is 2 times the length of the smaller part.

In our case,

The median KB is split into two parts such that the longer part KM is 2 times the length of the smaller part MB.

i.e.

KM = 2 MB

Given KM = 16.8

so substitute KM = 16.8 in the equation KM = 2 MB

16.8 = 2 MB

MB = 16.8/2

MB = 8.4

Therefore, the value of MB = 8.4

Simplify the sum. (4u3 + 4u2 + 2) + (6u3 – 2u + 8)

Elan Coil [88]

Answer:

$10u^{3}+4u^{2}-2u+10$ or $2(5u^{3}+2u^{2}-u+5)$

Step-by-step explanation:

we have

$(4u^{3}+4u^{2} +2)+(6u^{3}-2u+8)$

step 1

Group terms that contain the same variable

$(4u^{3}+6u^{3})+(4u^{2})+(-2u)+(2+8)$

step 2

Combine like terms

$(10u^{3})+(4u^{2})+(-2u)+(10)$

step 3

Eliminate parenthesis

$10u^{3}+4u^{2}-2u+10$

step 4

Factor the number $2$

$2(5u^{3}+2u^{2}-u+5)$

D'Angelo bought two shirts at a special sale. He paid the full price of $19.99 for one shirt and got a second shirt of the same

Alex

Answer: $2.55

Step-by-step explanation:

He bought the second shirt for half off the first shirt's price. He therefore bought it at:

= 19.99/2

= $10.00

Total paid for both shirts is therefore:

= 19.99 + 10

= $29.99

Sales tax is 8.5% so he paid:

= 29.99 * 8.5%

= ‭2.54915‬

= $2.55
