Estoy de acuerdo con lo que dice MamaLlama. Matemáticas totalmente no mama, que las rocas!

I agree with what he says MamaLlama. Fully Math does not suck, it rocks!

I think that this is a very long winded answer

you must work out the probability of 0 than 1 then.... all the way up to 19

sum of r from 0 to 19 of 

40Cr * 0.85^r * 0.15^(40-r)

I apologise for the presentation.

I am on my phone

Just multiply both sides by 8

that's it : )

I've corrected it now, thank you. :) I took the wrong approach, and didn't fully complete the question. I gave him bounds by accident instead of following through.

thanks

i like negative numbers so they are easy for me to solve

math doesn't suck, it's awesome!

Thanks for your answer. I really would love some explanation and if you can show me how to solve this problem by using u-substituiton I would appreciate.

Thanks again. :)

You should look again at Q5.

(Hint: If the tension equals the weight, then the net force is zero.  If the net force is zero the object isn't accelerating.)

.

If he lost 13% of his weight, he must must weigh (100 - 13)%  = 87% of what he used to....

So......to find the "new" weight......just multiply  158 x .87........!!!

219 / 398  = about 55%

So, subtracting 219 from 398 is taking away about 55% of 398.....or, looked at another way...the result, 179, is about 45% of 398

Anonymous has provided the correct answer.....let's enumerate a little further...

We have

a + b = 13

a - b =    5        add these equations together

2a = 18            divide both sides by 2

a = 9                and using a + b = 13, we have

9 + b = 13        subtract 9 from both sides

b = 4

And there you go......

36hk^3 and 60k^2m

The greatest factor of 36 and 60 is 12

The greatest factor of  k^3 and K^2 is k^2  ..... so we have

So, combining these, the gcf  =  12k^2

Very nice, saseflower.....!!!

56-78+99-100 = -23

What we are looking for is this:

⁵√32     ....   and this is equal to 2

(-5 + 1x - 4) + 3x - 5

-9 + 1x + 3x - 5

-14 + 4x

it's 1 25/100 which simplifies to 1 1/4

you use slope intercept form which is:

y2 - y1

x2 - x1

The sine of an angle can only take on values from -1 to 1. Thus, the given angle cannot exist.
