Answer:
1
Step-by-step explanation:
Equation of variance:
Total Variance = sum (i=1, N) {c^2,variance^2}
= c1^2*variance1^2 + c2^2*variance2^2 + .....
Variance of X = 1
Variance of Y = 5
Variance of Y - 2X = (1^2)*(5) - (2^2)**(1)
= 5 - 4 = 1
Answer:
-20
Step-by-step explanation:
Standard form for circle with radius r and center (h,k) is
(x-h)^2+(y-k)^2=r^2
r=36
center at -2,-7
(x-(-2))^2+(y-(-7))^2=36^2
(x+2)^2+(y+7)^2=1296

Hope this helps!
Answer:
Step-by-step explanation:
-17(y - 2) = -17y + 64
-17y + 34 = -17y + 64
-17y + 17y = 64 - 34
0 = 30 (incorrect)
this system has NO SOLUTIONS
