Answer:

Therefore the correct answer is A.) 84.88%

Step-by-step explanation:

i) λ = 2

ii) λ for three units = 2 $\times$ 3 = 6

iii) P(x ≥ 4) = 1 - P(x < 4) = 1 - {P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) }

= 1 - { $\frac{e^{-6}6^{0} }{ 0!} + \frac{e^{-6}6^{1} }{ 1!} + \frac{e^{-6}6^{2} }{ 2!} + \frac{e^{-6}6^{3} }{ 3!}$ }

= 1 - (0.0025 + 0.0149 + 0.0446 + 0.0892)

= 0.8488

Therefore the correct answer is A.) 84.88%

Write the quadratic function in standard form. y=2(x - 3)² +9

xz_007 [3.2K]

Answer:

y = 2x^2 - 12x + 27

Step-by-step explanation:

Step 1: Distribute the power

y = 2(x - 3)² + 9

y = 2(x^2 - 6x + 9) + 9

y = 2x^2 - 12x + 18 + 9

y = 2x^2 - 12x + 27

Answer: y = 2x^2 - 12x + 27
