Answer:

You have three card : 3, 4, 5 and 6.

You first pick one card randomly, the probability of picking a 3 is:

P = 1/4

You then pick a second card without putting the first card back, the probability of picking a 3 is:

P = 1/3

=> The probability of picking a 3 and then picking a 3:

P = (1/4) x (1/3) = 1/12

Hope this helps!

Answer:

g(x) = 3(x-9)(x-5)

Zeros: x = 9 and x = 5.

Step-by-step explanation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]\bigtriangleup = b^{2} - 4ac[/tex]

In this question:

[tex]g(x) = 3x^{2} - 42a + 135[/tex]

So

[tex]a = 3, b = -42, c = 135[/tex]

[tex]\bigtriangleup = (-42)^{2} - 4*3*135 = 144[/tex]

[tex]x_{1} = \frac{-(-42) + \sqrt{144}}{2*3} = 9[/tex]

[tex]x_{2} = \frac{-(42) - \sqrt{144}}{2*3} = 5[/tex]

So

g(x) = 3(x-9)(x-5)

Zeros: x = 9 and x = 5.

Answer:

The answer is 364. There are 364 ways of choosing a recorder, a facilitator and a questioner froma club containing 14 members.

This is a Combination problem.  

Combination is a branch of mathematics that deals with the problem relating to the number of iterations which allows one to select a sample of elements which we can term "r" from a collection or a group of distinct objects which we can name "n". The rules here are that replacements are not allowed and sample elements may be chosen in any order.

Step-by-step explanation:

Step I

The formula is given as

[tex]C (n,r) = \frac{n}{r} = \frac{n!}{(r!(n-r)!)}[/tex]

n (objects) = 14

r (sample) = 3

Step 2 - Insert Figures

C (14, 3) = [tex](\frac{14}{3})[/tex] = [tex]\frac{14!}{(3!(14-3)!)}[/tex]

= [tex]\frac{87178291200}{(6 X 39916800)}[/tex]

= [tex]\frac{87178291200}{239500800}[/tex]

= 364

Step 3

The total number of ways a recorder, a facilitator and a questioner can be chosen in a club containing 14 members therefore is 364.

31×5=155

155÷46=3.369565217

155/46

3 and 17/46

Step-by-step explanation:

a= the height of the triangle=h

[tex]h^{2} = ef[/tex]

by ef, e= 18 & f=4

so...

[tex]h^{2} = 18 \times 4 = 72[/tex]

so you put both of them in a square root

[tex] \sqrt{h} = \sqrt{72}[/tex]

so the answer will be

[tex]h = \sqrt{72} = 6 \sqrt{2} [/tex]

Answer:

45 degrees

Step-by-step explanation:

The sum of the angles of a triangle always adds up to 180.

10x + 8x + 5 + 85 = 180

Simplify by combining like terms.

18x + 90 = 180

Subtract 90 from both sides.

18x = 90

Divide both sides by 18.

x = 5 degrees

But the question didn't ask for x, it asked for angle A. So plug back in.

A = 8x + 5

A = 8(5) + 5

A = 40 + 5 = 45 degrees

Answer:

[tex]45 \: \: degrees[/tex]

Step-by-step explanation:

[tex]10x + 8x + 5 + 85 = 180 \\ 18x + 90 = 180 \\ 18x = 180 - 90 \\ 18x = 90 \\ \frac{18x}{18} = \frac{90}{18} \\ x = 5[/tex]

[tex]angle \: \: \: a = 8x + 5 \\ = 8 \times 5 + 5 \\ = 40 + 5 \\ = 45 \: \: degrees[/tex]

hope this helps

Answer:

x=-60/24 or -5/2

Step-by-step explanation:

u have to find X

2/4x - 1/2 = 1/3 + 5/6x

subtract 2/4x from both sides

to do that u need to have common denominator

2/4= 6/12

5/6=10/12

-1/2=1/3+4/12x

subtract 1/3 on both sides and u need common denominator

-1/2=-3/6

1/3=2/6

-5/6=4/12x

multiply 12/4 on both sides

x=-60/24

Answer:

x=-5/2

Step-by-step explanation:

2/4x-1/2=1/3+5/6x

-5/6x           -5/6x

2/4x-5/6x-1/2 =1/3

+1/2                  +1/2

6/12x-10/12x=2/6+3/6

-4/12x=5/6

x=5/6:(-4/12)=5/6*(-12/4)=-5/2

x=-5/2
