Mathematics
1 answer:
Ivanshal [37]3 years ago
7 0

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

Answer:

The difference in area between the trapezoid and the rectangle is 10 in²

Step-by-step explanation:

The dimensions of the trapezoid are given as follows;

Base 1, a = 12 in

Base 2, b = 10 in

Height, h = 10 in

Area, A of trapezoid;

A = \frac{a+b}{2} h = \frac{10+12}{2} 10 = 110 in^2

The dimensions of the rectangle are given as follows;

Base = 12 in

Height = 10 in

Area, A of rectangle;

Base × Height = 12 × 10 = 120 in^2

Therefore, the difference in area between the two packages is found as follows;

Difference in area between trapezoid and rectangle = 120 - 110 = 10 in²

The difference in area between the trapezoid and the rectangle = 10 in².
