thanks Geno, I haven't seen that notation.

This is the notation that I know as the complement of A  

$$P(\bar A)$$

Thanks maththis - it is great that you answered this question.  

$${\frac{{\mathtt{8}}}{{\mathtt{1}}}}$$ divided by $${\frac{{\mathtt{1}}}{{\mathtt{3}}}}$$ would equal $${\mathtt{24}}$$ your correct but you need to show work if your working out a math problem from a textbook so to get the answer you would have to rewrite the problem but turn the 8 into a fraction which would be 8/1 then change the divsion sign into a mutiplication sign and flip 1/3. $${\frac{{\mathtt{8}}}{{\mathtt{1}}}}$$ x $${\frac{{\mathtt{3}}}{{\mathtt{1}}}}$$  8x3=24

                                                                                                                          1x1=1

so the answer would be $${\frac{{\mathtt{24}}}{{\mathtt{1}}}}$$ which is equal to 24. i find fractions easy i caught on to them very fast. geno3141 was right but i wanted to explain the problem so they would be able to know how the answer was found

The calculator at this site can be used to find a decimal approximation of √π.

To divide by a common fraction, multiply by the reciprocal:

8 ÷ (1/3)  =  8 x (3/1)  =  8 x 3  =  24.

Some examples from physics and engineering are: calculating work, kinetic energy, pressure, and force.

ln 20*log 5 * log e*log 2/log 20/log 25*log 100/log 16 =  5/4

If you do it by Pascal's Triangle:

Row 0:    1

Row 1:    1  1

Row 2:    1  2  1

Row 3:    1  3  3  1

Row 4:    1  4  6  4  1  

Row 5:    1  5  10  10  5  1

Row 6:    1  6  15  20  15  6  1

Row 7:    1  7  21  35  35  21  7  1

Row 8:    1  8  28  56   70 ...

Row 9:    1  9  36  84  126  ...

Row 10:  1  10  45  120  210 ...   <--->  1x^10 + 10x^9y^1 + 45x^8y^2 + 120x^7y^3

If you do it by combinations, you want  10nCr7 = 120  

(the 10 comes from row 10, determined by the sum of the two exponents, the 7 comes from the exponent of the x-term). 

nine plus ten equals 19 $${\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{10}} = {\mathtt{19}}$$

If we said 5.5ft below the water surface....we'd be correct

If we considered the top of the water to be "0" and you said -5.5ft, I would understand that, too....

Either way.........you got the correct answer.....5.5

We won't dwell on semantics......

twenty one

14 + √(168)/2                   Divide 168 into two parts, one a perfect square (4) and the other what's left (42).

=  14 + √(4)√(42)/2          Repalce √(4) with its equivalent 2.

=  14 + 2√(42)/2               Cancel the 2 in the numerator with the 2 in the denominator.

=  14 + √(42)

51 degrees 9 minutes 37 seconds divided 8.54

Let's convert this to decimal degrees =

51 + 9/60 + 37/3600 = 51.1602

Divide this by 8.54 = about 5.99 or about 6

-----------------------------------------------------------------------------------------------------------------------------

Vamos a convertir esto en grados decimales =

51 + 9/60 + 37/3600 = 51.1602

Dividir esta por 8,54 = aproximadamente 5,99 o aproximadamente 6

Since there are 6 b***s and they are each equally likely to be chosen, the probability that any one is randomly chosen is 1/6. It doesn't matter what number is on the ball.

There are a total of 12 persons. You will pick 2 of them; since it is a committee, order is not important. This is a combination of 12 persons, taken 2 at a time:  12nCr2 = 66.

By hand:  12nCr2  =  12! / [2! ·10!]

it could be 5.5 [5 1/2]  or 5 im really not good at math but he's right it could be expressed as a negitive but thats not really the right format or whatever

A' is the complement of A; which means that if A is true, A' is false, and if A is false, A' is true.

A and A' cover all possibilities, with no overlap.

Thus P(A) + P(A') = 1.00.

So if P(A) = 0.72, P(A') = 1.00 - P(A) = 1.00 - 0.72 = 0.28.

i dont know so im not really the person to answer this but fomat that should problably be used is as 6.5 ft but i dont know so i dont have an answer sorry

can't you work it out maththis?

Its 80 - 74.5

80-74=6

80-74.5 must be less than 6    Don't you think so?

51+9/60+37/3600 / 8.54

$${\mathtt{51}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{9}}}{{\mathtt{60}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\frac{{\mathtt{37}}}{{\mathtt{3\,600}}}}}{{\mathtt{8.54}}}} = {\mathtt{51.151\: \!203\: \!486\: \!859\: \!224\: \!6}}$$  degrees

0.1512034868592246*60=

$${\mathtt{0.151\: \!203\: \!486\: \!859\: \!224\: \!6}}{\mathtt{\,\times\,}}{\mathtt{60}} = {\mathtt{9.072\: \!209\: \!211\: \!553\: \!476}}$$   minutes

$$\left({\mathtt{0.151\: \!203\: \!486\: \!859\: \!224\: \!6}}{\mathtt{\,\times\,}}{\mathtt{60}}{\mathtt{\,-\,}}{\mathtt{9}}\right){\mathtt{\,\times\,}}{\mathtt{60}} = {\frac{{\mathtt{1\,850}}}{{\mathtt{427}}}} = {\mathtt{4.332\: \!552\: \!693\: \!208\: \!56}}$$

So we have  51 degrees,  9 minutes and 4 seconds

Tenemos 51 grados, 9 minutos y 4 segundos

Don't be sorry maththis :)  Just give us the correct answer.  :)

oh im sorry

NO it shouldn't be negative Chris.    NOT for the way the question is phrased.

$$\frac{3}{7}\times -14\\\\
=\frac{3}{7}\times \frac{-14}{1}\\\\
=\frac{3}{1}\times \frac{-2}{1}\\\\
=\frac{3}{1}\times \frac{-2}{1}\\\\
=-6$$
