The diameter of the circle can be found by using the distance formula with the two points given...
d^2=(4--10)^2+(6--2)^2
d^2=14^2+8^2
d^2=260
d=√260
d=2√65
Since the radius is just half of the diameter, r= √65
The center of the circle will just be the midpoint (the average of the coordinates of the two endpoints) of the two points given so:
c=(-10+4)/2, (-2+6)/2
c=(-3,2)
The standard form of the circle is:
(x-h)^2+(y-k)^2=r^2, where (h,k) is the center of the circle so we can say:
(x+3)^2+(y-2)^2=65
55 because as u can see in the opposite side it’s 55 and the z is in the other side but the same amount of degrees
Answer: I think it’s 46
Step-by-step explanation: Because you add up the miles he drove them divide them by how long he drove
Ex 55+75+100=230 then you divide that by 5 hours = 46 per hour
To solve the problem we must know about the correlation coefficients.
<h3>What is the
correlation coefficient?</h3>
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
- 1 indicates a strong positive relationship.
- -1 indicates a strong negative relationship.
- A result of zero indicates no relationship at all, therefore, independent variable.
The correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".
Given to us
- The correlation coefficient for the data is −0. 9847.
As we can see that the value of the correlation coefficient is 0.9847, therefore, it is close to 1 means the relationship is strong, while the '-' symbol denotes that the relationship is negative.
Hence, the correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".
