!!PLEASE HELP ME!!

Over [174]

Answer:

(3x^2+6x)/(x^2-16)

Step-by-step explanation:

When multiplying fractions you just go straight accross

this means that our fraction is equal to

((x+2)(3x))/((x-4)(x+4))

The numerator is quite easy 3x(x+2)=3x^2+6x

The second one is a little tough at first and if you need help I would reccomend using khan academy

but pretty much you get x^2-16

put them together and get your answer

A bridge hand is made up of 13 cards from a deck of 52. find the probability that a hand chosen at random contains at least 3 ki

Vlad [161]

1.
In total there are C(52, 13) ways that we can pick a hand, that is $\frac{52!}{13!39!}$

2.
P(a hand contains at least 3 kings)
=P(a hand contains exactly 3 kings)+P(a hand contains 4 kings)

3.
first let's find P(a hand contains exactly 3 kings):

P(a hand contains exactly 3 kings)
=n(a hand contains exactly 3 kings)/C(52, 13)

n(a hand contains exactly 3 kings)=C(4, 3)*C(48, 10)

where C(4,3) is the total number of ways we can pick 3 out of 4 kings,

C(48, 10) is the number of picking 10 letters to complete a hand, out of the 52-4=48 non-king cards.

so P(a hand contains exactly 3 kings)=[C(4, 3)*C(48, 10)]/C(52, 13)

4. with the same reasoning as in step 3:

P(a hand contains 4 kings)=n(a hand contains 4 kings)/C(52, 13)

= [C(4, 4)*C(48, 9]/C(52, 13)

5.

P(a hand contains at least 3 kings)
=P(a hand contains exactly 3 kings)+P(a hand contains 4 kings)

=[C(4, 3)*C(48, 10)]/C(52, 13)+ [C(4, 4)*C(48, 9)]/C(52, 13)

= $\frac{C(4, 3)*C(48, 10)+C(4, 4)*C(48, 9)}{C(52, 13)}$

= $\frac{4* \frac{48!}{10!38!} + \frac{48!}{9!39!}}{ \frac{52!}{13!39!} }$

simplify by 38! in the denominators and 48! in the numerators :

$\frac{4* \frac{1}{10!} + \frac{1}{9!39}}{ \frac{52*51*50*49}{13!39} } 

$

now simplify by 9! in all denominators:

$\frac{ \frac{4}{10}+ \frac{1}{39} }{ \frac{52*51*50*49}{13*12*11*10*39}}$

$\frac{ 0.426 }{ 9.7} =0.044$

The airplane Li's family will be flying on can seat up to 149 passengers. If 96 passengers are already on the plane, which graph

alexgriva [62]

A solid circle is at 53. Everything to the left of the circle is shaded.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The airplane can seat up to 149 passengers.

If 96 passengers are already on the plane.

The solution to the inequality would be used to find how many more people can board.

<h3>How to find the solution to the inequality that would be used to find how many more people can board?</h3>

Let x be the vacant seat.

So the equation will be.

x + 96 ≤ 149

On simplifying, then we get.

x + 96 ≤ 149

x ≤ 149 - 96

x ≤ 53

Thus, A solid circle is at 53. Everything to the left of the circle is shaded.
