Okay so one side is area is 10x10 or 100 there are 6 sides on a cube, so I can do 6x100 which is 600
:)
Answer:
x=2
PT=7
Step-by-step explanation:
set up the equation like this: PT=TQ
(4x-1)=(2x+3)
calculate to find x
x=2
put x into the equation for PT
4(2)-1=7

Answer:
1
Step-by-step explanation:
Given the question above :
The probability distribution :
X : ___ 1 ___ 2 ___ 3 ___ 4 ____ 5
P(x): _ 0.1 __ 0.1 __ 0.6 _ 0.1 __ 0.1
The Variance : Var(X) = (Σx²*p(x)) - μ²
μ = E(X) = Σ(X * p(x)) :
Σ(X * p(x)) = (1*0.1)+(2*0.1)+(3*0.6)+(4*0.1)+(5*0.1)
μ = 3
Var(X): [(1^2*0.1)+(2^2*0.1)+(3^2*0.6)+(4^2*0.1)+(5^2*0.1)] - 3²
= 10 - 9
= 1
Hence. Variance = 1
