Answer:
The equation is x² + y² = 144.
Step-by-step explanation:
This works the same way as before.
You know that at the origin, it equals (0, 0). So, we have no need to insert values for h and k. Therefore, it will just be x² + y² = r².
R is your radius, and this is given as 12 units. So, r = 12. Therefore, r² = 144.
Your final equation is x² + y² = 144.
The answer is (4). all u have to do is see what makes sense.
Hello,
Answer B
(x-(-5))²+(y-2)²=5²
(x+5)²+(y-2)²=25
Answer: <em>r</em> represents a significant linear correlation.
Step-by-step explanation:
GIven : Linear correlation coefficient: r = 0.543
Sample size: n= 25
Significance levle: 
Degree of freedom : n-2 = 25-2=23
Now, we check <em>r</em> critical value table for value with df = 23 and
.
Critical value = ±0.396 [From <em>r</em> critical value table]
Since r = 0.543 > 0.396, that means there is significant linear correlation.
Hence, <em>r</em> represents a significant linear correlation.
