Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

inequality
distribution
PEMDAS

<h3>given:</h3>

$3(1 - 2x) > 3 - 6x$

<h3>to solve:</h3>

<h3>let's solve:</h3>

$step - 1 : define\\ 3(1 - 2x) > 3 - 6x$

$step - 2: distribute\\ 3 - 6x > 3 - 6x$

$step - 3 : \\ add \: 6x \: to \: both \: sides$

$3 - 6x + 6x> 3 - 6x + 6x$

$3 > 3$

$\therefore \: the \: statement \: is \: false \: for \: any \: value \: of \: x \: because \: both \: sides \: are \: identical$

therefore,

$x \in ∅$

Assume that the Poisson distribution applies and that the mean number of aircraft accidents is 9 per month. Find P(0), the prob

Ugo [173]

Answer: 0.0001

It is unlikely to have a month with no aircraft accidents .

Step-by-step explanation:

Given : Mean number of aircraft accidents = 9 per month

The Poisson distribution formula :-

$\dfrac{e^{-\lambda}\lambda^x}{x!}$ , where $\lambda$ is the mean of the distribution.

If X = the number of aircraft accidents per month, then the probability that in a month, there will be no aircraft accidents will be :-

$\dfrac{e^{-9}(9)^0}{0!}=0.000123409804087\approx0.0001$

Hence, the probability that in a month, there will be no aircraft accidents = 0.0001

Since this is less than 0.5 , therefor it is unlikely to have a month with no aircraft accidents .

Andrea chai tea solve the equation 1/4(x+12)=2.What was his mistake

lara31 [8.8K]

Answer:

He was supposed to cross multiply the equation in the original equation. Step 2 was a wrong expression

Explanations:

The given equation is:

$\frac{1}{4}(x\text{ + 12) = 2}$

Cross multiply the equation, the equation becomes:

$x\text{ + 12 = 8}$

x = 8 - 12

x = -4

His mistake was in step 2, he did not properly expand the equation

The proper step was to cross multiply in step 2
