Strong correlation: -0.91, 0.82
Medium correlation: -0.49, 0.54
weak correlation: 0.26, -0.18
If the decimal starts with 7,8, or 9 (like .82 or .91), it is strong correlation.
If the decimal starts with 6,5,4 (like .54, .49) then it is moderate correlation.
If the decimal starts with 1,2 or 3 (like .26) then it is weak correlation.
The negative signs have no effect.
Answer:
8.60
Step-by-step explanation:
A^2+B^2=C^2
5*5=25 7*7=49 49+25= 74
√ 74= 8.602...
Answer:
m<MLK = 65°
Step-by-step explanation:
Measure of intercepted arc KM = 130°
<MLK is the inscribed angle of the intercepted arc.
Therefore, measure of inscribed angle = ½ the measure of its intercepted arc.
Thus:
m<MLK = ½(130)
m<MLK = 65°
<span>Z $ xy then Z = Kxy. When x = 2 and y = 3, and Z = 60, our constant of variation becomes
60 = K * 2 * 3
K = 10. Our constant of proportionality equals 10. We would need that in the second part of the equation.
When x = 4 and y = 9, we have
Z = 10 * 4 * 9 = 360</span>
X^2+y^2-6x+2y-36=0. Use the equation of the circle (x-h)^2+(y-k)^2=radius^2, center (h,k) is (3,-2)
