Answer:

w<6 THE SMALL LINE UNDER THE LESS THAN SIGN IS STILL THERE I JUST CANNOT ADD IT

Step-by-step explanation:

first solve the equation to the right.

-3(2w+1) = -6w-3

now solve the whole equation

-33-w< -6w-3

-w+6w < -3+33

5w < 30

divide the 5 from both sides to simplify

5/5w < 30/5

w < 6

THE ANSWER IS w < 6

Rationalize the expression. Write it in simplest form.<br><br> 9x/√-2x-11
GenaCL600 [577]
This appears to be just an expression we are simplifying, not an equation we are solving.  I THINK you are saying that the expression looks like this:
\frac{9x}{ \sqrt{-2x-11} }
If you rationalize the denominator, you would get this expression:
\frac{9x}{ \sqrt{-2x-11} } * \frac{ \sqrt{-2x-11} }{ \sqrt{-2x-11} }
which, after simplifying, looks like this:
\frac{9x \sqrt{-2x-11} }{-2x-11}
and that's as simple as I can see that one getting.  You can't factor anything out of the denominator to cancel with the numerator, so I think you're as simple as you can get there!

Simplify
Scorpion4ik [409]

Answer:

1

Step-by-step explanation:

using the rule of exponents

(\frac{a}{b}) ^{-1} = \frac{b}{a} , then

\frac{123}{321} × \frac{456}{654} × \frac{789}{987} × \frac{321}{123} × \frac{654}{456} × \frac{987}{789}

[ \frac{123}{321} × \frac{321}{123} = 1 , \frac{456}{654} × \frac{654}{456} = 1 , \frac{789}{987} × \frac{987}{789} = 1 ]

= 1 × 1 × 1

= 1

4.8.4 Raw materials are studied for contamination. Suppose that the number of particles of contamination per pound of material i
forsale [732]

Answer:

700 lbs and 3.742

Step-by-step explanation:

Given that raw materials are studied for contamination. Suppose that the number of particles of contamination per pound of material is a Poisson random variable with a mean of 0.02 particle per pound.

a) To get 14 particles of contamination we must have

expected number of pounds = \frac{14}{0.02} \\=700

b) Since for 700 pounds particles expected are 14 we can say in  a Poisson distribution mean and variance are equal

i.e. Var (700 lbs to obtain 14 particles of contamination ) = 14

Std deviation =\sqrt{14} =3.742

Let A and B be the two people who are able to drive. If A is driving, there are 4! ways to arrange the remaining peoplein the car seats. If B is driving, there are also 4! ways to arrange the remaining people. The number of arrangements 'n' is:

n=2*4!\\n=2*4*3*2*1\\n=48\ ways

They can be arranged in 48 ways.
