Answer:
Step-by-step explanation:
Given, :
x P(x)
0 0.900
1 0.09
2 0.007
3 0.003
The expected variance ; Var(X) = x²*p(x) - E(X)²
The expected mean, E(X) = x*p(x)
E(X) = (0*0.9) + (1*0.09) + (2*0.007) + (2*0.003) = 0.113
Var(X) = [(0^2*0.9) + (1^2*0.09) + (2^2*0.007) + (3^2*0.003)] - 0.113^2
Var(X) = 0.145 - 0.012769
Var(X) = 0.132
The answer is B, two cups of milk for every 8 cups of bread.
This is because when using a recipe you want to make sure to get the proportions right and the ratio of milk to bread is 2:8
Point A before being rotated = (1,-2)
A point (x,y) is rotated counterclockwise by 90°. The result will be (-y,x)
If point (1,-2) rotated counterclockwise by 90°, the result will be (2,1)
ANSWER: A. (2,1)
