Thank you for checking. :))

Some days I make dumb mistakes... like yesterday, I did 2+3 = 6

Use the word little in a sentence.    <=======   this is a sentence with the word in it !

Emily ate 4

Jennifer ate 3

Kevin ate 2

John ate 1

= 500 ( 1 + .03) ¹⁸  = $............         .03 is 3% periodic interest       18 is the number of periods ( 18 years)

6 out of 10 originally were women

   24 women leave  and now   5 out of 8 are women

6/10 x    =  ( 5/8 * 8400  + 24)

x = original attendance =  10/6 (5/8*8400+24) = 8790    

8790 - 8400 = 390 people left

The vertex is at (4,18).

X intercepts is when y = 0. 

 f(0)=0

f(2)=0

So the intercepts are 0 and 2.

15. :))

At 15 it'll be 1/2. 

Then at 16, it'll be 1 (1/2*2)

=^._.^=

The 15 th day it was 1/2 covered.....then it doubled to total coverage on day 16

Just to say I did not submit the previous mistake you made, I was checking if you did it right but when I checked it, you subtracted by total - women and I did not submit that and said that was wrong. I check the one where you edit the actually answer and it was correct both of them are total.

HAHHAHAHAHHAHAHA..... this always tricks my brain but it is 27 because it doubles 

My answer is also A 

YAYYYY, I'm sorry about that previous mistake. 

=^._.^=

3*2*1 = 6 ways to choose 3 marbles of different colour. 

(2*3*4)/(9*8*7) = probability of choosing 3 marbles of different colour, in  a specific order. 

6*(2*3*4)/(9*8*7) = 2/7

I hopet his helped. :))

=^._.^=

That's correct now.

yea, it's fixed now. 

=^._.^=

I don't think you were supposed to do 8790-5250=3540

Oh no. :((

Which part do you think is wrong?

Ohhh, I see. 

I'm sorry. 

=^._.^=

That's wrong

After some leaving

8,400 total

men to women, 3:5

Men: 3150

Women: 5250

Before

Women: 5274

Men: 3516

Total: 8790

8790-5250=3540

So 3540 people left. :))

Edit: 

I subtracted the wrong number. 

8790-8,400 = 390 (I subtracted women instead of ttal)

=^._.^=

7 C 4 = 35

8 C 4 = 70        there were 7 in the original group

Let x be the number of students. 

2*(x)(x-1)(x-2)(x-3)/24 = (x+1)(x)(x-1)(x-2)/24

2(x-3) = (x+1)

2x-6 = x+1

x = 7

I hope this helped. :))

I don't think you question fully transfered. :))

Generally, when dealing with "round to the nearest hundredth", you can just plug the numbers into a clac. 

So if my answer was sqrt(2), I'd just type that in a calc and get 1.4142135623 and round to 1.41. 

If it says "leave your answer in simplest radical form", just keep it as sqrt(2). 

To solve a quadratic, you can either use the quadratic formula, or you can factor if the number is nice. :))

There's a nice khan academy video on both of those topics.

8x + 5      -   ( 5-x)         for x <5    the value will always be negative ....so the abs value will be positive..

                                           ..multiply value in the abs bracket by -1 and this is what you will get

= 9x
