Answer:
42.5
Step-by-step explanation:
When you do the bottom corners, it 2x2 divided 2 then you do 2x2, then 5x2 divided by 2 you do 3.5x9.0 when you add all of them up you get 42.5.
Answer:
A = 64 units²
Step-by-step explanation:
A = 1/2bh
Step 1: Define
A = ?
b = 16 units
h = 8 units
Step 2: Substitute and Evaluate
A = 1/2(16 units)(8 units)
A = (8 units)(8 units)
A = 64 units²

Answer:
1. 0.108368
2. 0.188876
Step-by-step explanation:
Let X be the exponential random variable that represents the lifetime of a computer.
i.e. 
The probability that the computer will function more than 2000 days can be computed as follows:
P(X > 2000)
: 
P(X > 2000) = 1 - P(X< 2000)
P(X > 2000) = exp(-2000/β) = e⁻²²
P(X > 2000) = 0.108368
2.
By applying conditional probability;
