Answer:
5/6 is your answer
Step-by-step explanation:
no. of favourable observation/ total no of observation
Equation: y = 1.5x + 3
10.50 = 1.5x + 3
1.5x = 7.5
x = 5

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
Answer:
(-4,16)
Step-by-step explanation:
1/2x+18=5/2+26
1/2x=5/2x+8
-2=8 divided by -2
Equals x=-4
Plug in -4 in one of the equations
1/2(-4)=18= 16
It shows that a parabola can be described by tangents formed by lines with decreasing y-intercepts and equivalently increasing x-intercepts.
