Answer:

<h2> B. 0.65 </h2>

Step-by-step explanation:

The options to this question are

A. 0.55

B. 0.65

C. 0.35

D. 0.45

The correlation coefficient is a statistical measure of the realtionship between variables in a study, this measure is about how strong are realted those variables. The correlation could be strong or weak, could be negative or positive.

The range or interval where the correlation coefficent falls is from -1 to 1. If the coefficient is outside this interval, there's an error in the data set.

Now, if the coefficient is zero, it means there's no correlation between variables. But, if the coefficient is near to 1, it means the correlation is positive and strong.

Therefore, in this case, the right answer is B. 0.65, because it's the closest value to 1.

A. 0.55

B. 0.65

C. 0.35

D. 0.45

0.65  represents the strongest correlation.

Answer: Option B.

<u>Explanation:</u>

In statistics, correlation or dependence is any measurable relationship, regardless of whether causal or not, between two arbitrary factors or bivariate information. In the broadest sense connection is any measurable affiliation, however it normally alludes to how much a couple of factors are straightly related.

For two factors, a statistical correlation is estimated by the utilization of a Correlation Coefficient, spoke to by the image (r), which is a solitary number that depicts the level of connection between two factors.

The mold for a cone has diameter of 4 inches and is 6 inches tall what is the volume of the cone mold to the nearest tenth
Nesterboy [21]
The formula for the volume of a cone is
v = ( 1 / 3) h pi r^2
where h is the height of the cone
pi is 3.1416
r is the radius of the cone

since diameter is given
D = 2r
r = D/2 = 4/2 = 2 in

substitute the given
V = (1/3) (6) (3.1416) (2^2)
V = 25.1 cubic in

Please help me ASAP! I will friend you (probably)! The first correct answer will get brainiest! Terry and Tao are canoeing on a
ivann1987 [24]
<span>erry starts rowing at 2 pm from the west end of the lake, and Tao starts rowing from the east end of the lake at 2:05 pm. 
------
Terry DATA:
rate = 60 meter/min ; time = x min ; distance = r*t = 60x meters
-----
Tao DATA:
rate = 40 meter/min ; time = x-5 min ; distance = r*t = 40(x-5) meters
--------------------------
If they always row directly towards each other at what time will the two meet?

------
Equation:
dist + dist = 2000 meters
60x + 40(x-5) = 2000
20x = 1800
x = 90 minutes
