<span>The correlation coefficient is a value that signifies correlation and dependence between two or more values. </span>The following statements are true:
- The correlation coefficient is a unitless number and must always lie between –1.0 and +1.0, inclusive.
- The correlation coefficient, r, gives us information about the strength and direction of a linear relationship between any two variables.
<span>- The larger r is in absolute value, the stronger the relationship is between the two variables.

Step-by-step explanation:
Answer:
Volume = 10562.96 cu ft
10.56 hr. to drain all the water
Step-by-step explanation:
V = 1/3Bh B = area of the base h = height
The base is a circle, so 
= 10562.96 cu ft
10562.96/1000 = 10.56 hr.
We know that
Applying the law of cosines:
<span>c</span>²<span> = a</span>²<span> + b</span>²<span> - 2abcos(C) </span>
<span>where: </span>
<span>a,b and c are sides of the triangle and C is the angle opposite side c </span>
<span>that is </span>
<span>150</span>²<span> = 240</span>²<span> + 200</span>²<span> - 2(240)(200)cos(C) </span>
<span>solve for C </span>
<span>22,500 = 57,600 + 40,000 - 96,000cos(C) </span>
<span>22,500-57,600-40,000 = -96,000cos(C)
</span>-75,100=-96,000cos (C)
cos (C)=0.7822916
C=arc cos(0.7822916)--------> C=38.53°°
<span>hence, </span>
<span>he should turn in the direction of island b by
180 - 38.53 </span><span>= 141.47 degrees</span>
Answer:
You did not include your graph, therefore I will explain in the step-by-step everything you should need to know.
Step-by-step explanation:
The standard slope formula is y=mx + b, where m = slope (rise/run) and b = the y intercept.
Using this knowledge, we know that this line has a slope of 5, or 5/1, which means that you will go up 5 and 1 to the right. Since there is no + b part, that means b = 0, so the line begins at 0,0. So, using this information, possible points include 0,0, 5,1, 10,2, 15,3, etc.
