Answer:
=14-(7*10)
Step-by-step explanation:
fourteen = 14 (base)
less = -
PRODUCT means multiplication
PRODUCT of seven and ten = 7*10
*Don't forget parenthesis
Answer= 14 - (7*10)
False, trigonometry is not the study of three dimensional shapes.
2(3x - 2) - 11x = -5x
6x-2 - 11x=-5x
10x-2
12x
I think it right
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
