Each trial is independent of every other one.....

So.....the probabilty of heads  = 1/2   and the probability of "A"   = 1/5.....so

P ( Heads and A )   =  (1/2) * (1/5)    =    1 / 10

Your "continued fraction" adds up to =Sqrt(2) =1.4142135623730.......etc.

The answer is 21

the answe is 4

I think this is the equation:

3a^2 + 4a = 2a^2 - 2a - 9

Subtract 2a^2 from both sides of the equation.

a^2 + 4a = - 2a - 9

Add 2a to both sides of the equation.

a^2 + 6a = -9

Add 9 to both sides of the equation.

a^2 + 6a + 9 = 0           \(\leftarrow\)          I think this is the standard form of the equaion.

Now we can factor the left side like this

(a + 3)(a + 3) = 0

(a + 3)^2 = 0

Take the square root of both sides.

a + 3 = 0

Subtract 3 from both sides of the equation.

a = -3

2x^2  + 4y

2(8)^2  +  4 (1.5)  =

128  +     6   =

134

Because that helps a lot.

x^5-x^4-3x^3+3x^2-4x+4=0

If we can add the coefficients and the result  = 0, then 1 is a root

So using synthetic division to find a reduced polynomial, we have

1  [  1    -1   - 3    +3   -4     4  ]

              1     0    -3     0     -4

     _____________________

      1     0    -3     0     -4    0

So.......the remaining polynomial   is       x^4  -  3x^2  -  4     factor this

(x^2 - 4) (x^2 + 1)    =

(x + 2) ( x - 2)  (x^2  + 1)

Setting the first two terms to  0 and solving for x we get that x  = -2  and x  = -2....and these are two other real roots

Finally.........set x^2 +  1  to 0

x^2  + 1  =  0      subtract 1 from both sides

x^2  =  -1        and x  =   i       and x  = -i      are the non-real roots

So the zeroes are      -2, 1, 2 , i, -i

\(2\frac13*7\frac38\)

Convert the mixed numbers into improper fractions.

\(= \frac73*\frac{59}{8}\)

Multiply the fractions.

\(=\frac{7*59}{3*8} \\~\\ =\frac{413}{24}\)

This cannot be reduced.

If you need the answer as a mixed number:   \(\frac{413}{24}=17\frac{5}{24}\)

Oh and also *Y'all

Thanks! ;)

I hope so.

Thank you

y = k/x      we need to find "k"   .....so.....

9  =  k / 4       multiply both sides by 4

36  = k

So....our function is :

y = 36 / x

That was kinda rude 

No and 3

No and 3 

i think he's saying but knowing internet people he's asking then again he might be female and be lesbian

Are u asking or saying?

Thank you for telling me. I appreciate it?????????

oh cool good for you for coming out like that have you told your parents

Here's a simple reason :

Note :    6  / 3   =  2       because 2 * 3  = 6        [ quotient *  divisor  = dividend  ]

But

3 / 0   =  ?         because.....  ?  *  0     cannot posssibly return a value of 3  ....  in other words,  quotient * divisor  is undefined
