Answer:

f=1/x^2-81

Step-by-step explanation:

Step 1: Multiply both sides by x^2-81.

fx3−81fx=x

Step 2: Factor out variable f.

f(x3−81x)=x

Step 3: Divide both sides by x^3-81x.

f(x3−81x)

x3−81x =x x3−81x f= 1 x2−81

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.

Negative solution for Multi-step equations

nydimaria [60]

Answer:

$\frac{1}{2}(4x+6)+3x=7x+9$

$\frac{1}{2}(4x+8)+3x=7x+9$

Step-by-step explanation:

By putting the numbers in the given equation,

$\frac{1}{2}(4x+6)+3x=7x+9$

2x + 3 + 3x = 7x + 9

5x + 3 = 7x + 9

(5x + 3) - 7x = (7x + 9) - 7x

(5x - 7x) + 3 = 9

-2x + 3 = 9

(-2x + 3) - 3 = 9 - 3

-2x = 6

$-\frac{2x}{2}=\frac{6}{2}$

-x = 3

x = -3

Therefore, our equation is correct which has a negative result.

In place of 6 if we use 8, value of x will be negative again.
