Answer:
A) x = 10-/3, y = 20
Step-by-step explanation:
Each level has 4 castles to conquered. Jackson completed 6.
Let x be the number of remaining levels and y is the total number of castles to defeat
For every x, there are 4 castles to conquered, 4x represents number of remaining levels and corresponding castles.
Since he has already conquered 6 levels 4(6) = 24 so
y=4x+24, A.
Answer:
Step-by-step explanation:
Given that X and Y are independent random variables with the following distributions:
x -1 10 1 2 Total
p 0.3 0.1 0.5 0.1 1
xp -0.3 1 0.5 0.2 1.4
x^2p 0.3 10 0.5 0.4 11.2
Mean of X = 1.4
Var(x) = 11.2-1.4^2 = 9.24
y 2 3 5
p 0.6 0.3 0.1 1
yp 1.2 0.9 0.5 0 2.6
y^2p 2.4 2.7 2.5 0 7.6
Mean of Y = 2.6
Var(Y) = 11.2-1.4^2 = 0.84
3) W=3+2x
Mean of w =3+2*Mean of x = 7.2
Var (w) = 0+2^2 Var(x)= 36.96
