Airline Fatalities One study showed that in a certain year, airline fatalities occur at the rate of 0.011 deaths per 100 million

Lelu [443]

Answer:

$P(X = 0) = 0.9891$

Step-by-step explanation:

Given

$\lambda = 0.011$

Required [This completes the question]

The probability of exactly 0 deaths

This probability follows a Poisson distribution, and it is given by:

$P(X = x) = \frac{e^{-\lambda}\lambda^{x}}{x!}$

For 0 deaths;

$x = 0$

So, the expression becomes

$P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{0!}$

$P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{1}$

$P(X = 0) = \frac{e^{-\lambda}*1}{1}$

$P(X = 0) = e^{-\lambda}$

Substitute 0.011 for $\lambda$

$P(X = 0) = e^{-0.011}$

$P(X = 0) = 0.9891$

<em>The probability of having exactly death is 0.9891</em>

Step-by-step explanation:

7,000 x 1/1000 = 7,000/1,000 = 7

7,000 - 7 = 6,993

how to calculate cube root without using prime factorization? and how to calculate ³√60? or something else that has a decimal re

Marat540 [252]

The cube root of 60 is 3.87 approximately.

Step by step solution:

We can calculate the cube root by Halley's method:

The formula is $\sqrt[3]{a} = x ((x^{3} + 2a)/(2x^{3} + a))$

where,

a = number whose cube root is being calculated

x = integer guess of its cube root.

Here a = 60,

Suppose x as 3

[∵ 3³ = 27 and 27 is the nearest perfect cube that is less than 60]

⇒ x = 3

Therefore,

∛60 = 3 (3³ + 2 × 60)/(2 × 3³ + 60)) = 3.87

⇒ ∛60 ≈ 3.87

Therefore, the cube root of 60 is 3.87 approximately.

Here , ∛60 is irrational because it cannot be expressed in the form of p/q where q ≠ 0.

Therefore, the value of the cube root of 60 is an irrational number.
