250% because you have to average the decimal

Thanks Gino for looking after those :)

Hi everyone,

We were on a roll today.  Lots of questions and answers but we got through them all so I am writing the wrap early today :)))    Oh, Rosala returned to - that is great :))))) 

Great answers from Kaepernicks, xXFareXx, CPhill, reinout-g, geno3141, SevenUp, Kitty<3, Anonymous4338, Phanolo, Hc2027, justinas, happy7 and Rosala.  Lots of helpers today.  That is great. Thanks everyone.  

Now for a few interest posts:

1) Rosala's back  Hip Hip Horray!

any real number divided by itself = 1  (except for 0)

I just added your birthday to our birthday list Happy7  :)

fair enough :)

We have a rat pack back.  It is not the same pack as before, we do miss DragonSlayer554 and Zegroes and Rose98.  But still it is great to have a rat pack back again.  From my observation the new 'rat pack' includes Rosala, Tiddle, TayJay, happy7, Jillybean and Anonymous4338  

Do not take offense to the term 'Rat Pack' it is a term coined by CPhill and it is most definitely a term of endearment :)))   CPhill and I both love having an active Rat Pack on the forum  

The 'Rat Pack' has been taking garbage posts and turning them into chat rooms although Jillybean made this one from scratch.   

Have a look at this post :)

Simple - You don't  :)

Ohh... lol

We would have a reciprocal....

Note...

x^3 / x^-2  =

(x^3 / 1) / ( x^-2) =

(x^3 / 1) / (1/ x^2) =

(x ^ 3 / 1) * (x^2 / 1) =

x^5

Does that make sense ??

Use the

CPhill I thought that if you get a negative exponent then you will have to get the reciprocal?

A  variable with  negative exponent in a fraction can always "travel" across the fraction bar. It's exponent then becomes positive......

So we have

x^3 / x^ -2 =

(x^3) * (x^2) =

x^5

I know math but I'm only average. According to my head:

I think you can't answer that....

$${\frac{{{\mathtt{x}}}^{{\mathtt{3}}}}{{{\mathtt{x}}}^{-{\mathtt{2}}}}} = {\frac{{{\left(\underset{{\tiny{\text{Error: Unknown Identifier}}}}{{\mathtt{x}}}\right)}}^{{\mathtt{3}}}}{{{\left(\underset{{\tiny{\text{Error: Unknown Identifier}}}}{{\mathtt{x}}}\right)}}^{-{\mathtt{2}}}}}$$

or

$${\frac{{\frac{{{\mathtt{x}}}^{{\mathtt{3}}}}{{\mathtt{1}}}}}{{\mathtt{x}}}} = {\frac{{\frac{{{\left(\underset{{\tiny{\text{Error: Unknown Identifier}}}}{{\mathtt{x}}}\right)}}^{{\mathtt{3}}}}{{\mathtt{1}}}}}{\underset{{\tiny{\text{Error: Unknown Identifier}}}}{{\mathtt{x}}}}}$$

Therefore, you cannot answer that without any given values..

This is the graphing calc that we usually use

on the web 2 calc just use the minus sign. :)

well. . . 0-0= 

You use the button with the plus sign on top of the minus sign. That button is also right next to the 0.

Divide 370.46 by 1881.18 and multiply that answer by 100. You'll need to round the answer.

The question will have to be more specific.

The amount of change is found by subtracting the initial location from the final location:  103 ft - 100 ft = 3 ft.

To find the percent of change, divide the amount of change by the initial amount and multiply that answer by 100:  3 ft / 100 ft x 100  =  3%. (This is an increase.)

a) A tree diagram is hard to explain in words, but I'm not sufficiently computer literate to provide a drawing.

So:  let the diagram start at point A.

From A, there are two paths, one is a successful path to B (with value 0.75) and the other is an unsuccessful path to C (with value 0.25).

There is no path from B because there is no need to take another test.

From point C, there are two paths, one is a successful path to D (with value 0.60) and the other is an unsuccessful path to E (with value 0.40)

There are no paths from D or E.

b) The only way for a student to fail is to go from A to C (0.25) and from C to E (0.40). To find the probability for going from A to E is 0.25 x 0.40  = 0.10.

c) Since the protability of failing is 0.10, the probability of succeeding is 0.90.

The probability of all succeeding is 0.90 x 0.90 x 0.90  =  0.729.

The slope of AC is:  m  =  (5 - 0) / (8 - 2)  =  5/6.

To change a slope into an angle, use invTan.  invTan(5/6)  =  39.8° (approx).
