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: 93
Triangle ABC is similar but not congruent to Triangle XYZ
When you dilate the size changes but the angles are the same with makes them similar and since the size of the triangles are different they cannot be congruent.
y=2-5x/4 x=8/5-4y/5
