Answer:

2e⁻² ≈ 0.271

Step-by-step explanation:

This is actually a Poisson distribution.  The probability is:

P(x; μ) = e^(-μ) (μˣ) / x!

P(2; 2) = e⁻² (2²) / 2!

P(2; 2) = 2e⁻²

P(2; 2) ≈ 0.271

Pls help!! Find the area of the lighter shaded region and round to the nearest tenth.
Elenna [48]

Answer:

5.1 cm² approximately

Step-by-step explanation:

A lighter= Area inscribed -1/2r² sin80°

A lighter=π r² (80°/360°) -1/2(5 cm)² sin 80°

A lighter=π(5cm)² (80°/360°) -1/2(5 cm)² sin 80°

A lighter=3.14*25cm²(80°/360°) - 12.5cm² sin 80°

A lighter=17.444…cm² - 12.31009... cm²

A lighter=5.13cm² approximately
