1 metre = 100cm
2 metres = 200cm

200 / 80 = 2.5

The auto parts department of an automotive dealership sends out a mean of 4.34.3 special orders daily. What is the probability t
Svetlanka [38]

Answer:

P(X = 5) = 0.166

Step-by-step explanation:

Given

Mean = 4.3

x = 5

Required

Determine the probability that the order is 5

This question can be answered using Poisson distribution.

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

Where

\alpha is used to represent the mean

and

\alpha = 4.3

x = 5

<em />e = 2.71828<em> ---- Euler's constant</em>

So, we have:

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

P(X = 5) = \frac{4.3^5  * 2.71828^{-4.3}}{5!}

P(X = 5) = \frac{4.3^5  * 2.71828^{-4.3}}{5* 4 * 3 * 2 *1}

P(X = 5) = \frac{4.3^5  * 2.71828^{-4.3}}{120}

P(X = 5) = \frac{1470.08443  * 0.01356859825}{120}

P(X = 5) = \frac{19.9469850243}{120}

P(X = 5) = 0.1662248752

P(X = 5) = 0.166 <em>Approximated</em>

The sum of a student's three score is 246. if the first is 14 points more than the second, and the sum of the first two is 6 mor
mr_godi [17]
Let the second score = x
⇒ second score = x

<span>the first is 14 points more than the second
</span>⇒ first score = x + 14

<span>the sum of the first two is 6 more than twice the third
</span>⇒ third score = 1/2 (x + x + 14 - 6) = x + 4

<span>The sum of a student's three score is 246
</span>⇒ x + (x + 14) + (x + 4) = 246
<span>
Solve x:
</span>x + x + 14 + x + 4 = 246
3x + 18 = 246
3x = 228
x = 76

second score = x = 76
first score = x + 14 = 76 + 14 = 90

Answer: 90
