It would be (x,y) = (-y,x). Rotating a figure 270 degrees clockwise is the same as rotating a figure 90 degrees counterclockwise. Hope this helps! :D Feel free to ask more questions.
Answer:
D
Step-by-step explanation:
Since 2 variables are inter-dependent (there is correlation between them given as 0.64), we need to use the formula shown below:
Var(x+y) = Var(x) + Var(y) + 2 * correlation coefficient * *
<em><u>Given Var(m) = 1600, Var(n) = 900 and correlation coefficient 0.64, we plug them into the formula and solve:</u></em>
Var (m+n) = Var(m) + Var(n) + 2 * correlation coefficient * *
= 1600 + 900 + 2(0.64)*Sqrt(1600)*Sqrt(900)
= 4036
correct answer d
Answer
x=2/3
Explanation
2x-24/8
2x=24/8
8x(2x)=24/8X 8
16x=24
devide both by 8
2x=3
x=2/3
