Question 2. 

1/4 of 160 = 40

1rst month = 40

2nd month = 1/4 of 40 = 10

3rd month = 2.5

In her 3rd month, she would pay $2.5

Here to help

:D

Very nice, LuckyDucky!!!!

(1/1*2)+(1/2*3)+(1/3*4)+(1/4*5)+ .............+(1/99*100) =

= [1/1 - 1/2] + [1/2 - 1/3] + [1/3 - 1/4] + ... + [1/98 - 1/99] + [1/99 - 1/100] = 1/1 - 1/100 = 99/100 

:D

a)  Green  = 300  (1/5)   =  60 times

b )  P(purple)  =  72  / 300   =    6/25

c) If spun 1000 times, Blue would come up

1000  (45) / (300)  =  (10/3) 45  =  150 times

Outcome         Void     Fail      Success

Freq                96        60          244

Rel Feq           .24      .15         .61

b)   1000 *.24    =    240 times

if i have a pentagonial pyramid with no given apothem, a given base side of 8, and a slant height of 20, how do I find the surface area of the shape as a whole?

Factors of 30  =  2,3,5,6,10,15,30

Relatively prime to 30 

83, 79, 77, 73, 71, 67, 61, 59, 53, 49, 47, 43, 41, 37, 31, 29, 23, 19, 17, 13, 11, 7

Some people just give a link and expect us to do it and they do not learn they just are answer hungry. 

Thank you!

AB  = sqrt  [ (-6 - 9)^2  + (6 - 6)^2) ]  =  sqrt  [ 15^2]  =  15

BC  =  sqrt  [ ((9- 9)^2  + ( -2 - 6)^2 ]  =   sqrt [ 64]  =  8

AC  =  sqrt [ (-6 - 9)^2  + (-2 - 6)^2) ] =  sqrt  [ 15^2  +8^2]  = sqrt [ 289]  =  17

Perimeter  =  15 + 8  +  17   =   40

                                        Spinner  A

                               2    4     6      8

                       1     3    5     7      9

Spinner B       3     5    7     9     11

                       5     7    9    11    13

b)  P(7)  =   3/12  =  1/4

So...if  120 people play  1/4  of them will spin a  "7"   =   30 people

So.....the school will  raise

120(20)  - 30(30)  =

2400  -  900  =

$1500

I'm sorry I can't help then

What is the direct issue you are facing

for example do you not understand the topic or is it a formula problem?

Instead of posting a link please ask what the problem you are facing is?

                                 Dice  A

                        1     2     3    4    5     6

               1       0     1     2    3    4     5

Dice B     2      1     0     1     2    3    4

               3       2     1     0    1    2     3

               4       3     2     1    0     1    2

               5       4     3     2    1     0    1

               6       5     4     3    2    1     0

P(1)  =   10 / 36   =   5 / 18

Score with a probability of 1/18  =   5

We have two 5's  out of 36 results  =  2/36  =  1/18

yay that's right! thanks CPhill! :)
