Poisson Distribution LEARNING OBJECTIVE: Calculate the probability of a poisson distribution. 3.00 The average number of bridge
ira [324]

Answer:

the required probability is 0.09

Option  a) 0.09 is the correct Answer.

Step-by-step explanation:

Given that;

mean μ  = 7  

x = 4

the probability of exactly 4 bridge construction projects taking place at one time in this state = ?

Using the Poisson probability formula;

P( X=x ) = ( e^-μ × u^x) / x!

we substitute

P(X = 4) = (e⁻⁷ × 7⁴) / 4!

= 2.1894 / 24

= 0.0875 ≈ 0.09

Therefore the required probability is 0.09

Option  a) 0.09 is the correct Answer.

What is the product of (7 x 10^-5) x (5 x 10^-8) <br> (7 x 10^-5) x (5 x 10^-8) = ? x 10^?
arsen [322]

Answer:

3.5\times10^-^1^2

Step-by-step explanation:

(7 \times 10^-5) \times (5 \times 10^-8)

Evaluate

(7 \times 5)\times(10^-^5\times10^-^8)

35\times10^-^5^-^8

35\times10^-^1^3

35\times10^1\times10^-^1^3

3.5\times10^1^-^1^3

3.5\times10^-^1^2

Thus, the answer is 3.5\times10^-^1^2

line AB has endpoints A (-3, 1) and B (4, 5), find the coordinates of point p on directed line segment AB that partitions AB in
Margarita [4]
<h3>Given</h3>

A(-3, 1), B(4, 5)

<h3>Find</h3>

coordinates of P on AB such that AP/PB = 5/2

<h3>Solution</h3>

AP/PB = 5/2 . . . . . desired result

2AP = 5PB . . . . . . multiply by 2PB

2(P-A) = 5(B-P) . . . meaning of the above

2P -2A = 5B -5P . . eliminate parentheses

7P = 2A +5B . . . . . collect P terms

P = (2A +5B)/7 . . . .divide by the coefficient of P

P = (2(-3, 1) +5(4, 5))/7 . . . . substitute the given points

P = (-6+20, 2+25)/7 . . . . . . simplify

P = (2, 3 6/7)
