egoroff_w [7]
Here is the answer to the given problem. So, what Christina wants to find out is the sum of the length after 10 throws given that in each throw, it retracts 70% of the original length. So to continue the given data, here are the results:
4: 1.029
5: 0.7203
6: 0.50421
7: 0.352947
8: 0.2470629
9: 0.17294403
10: 0.12106082
Since she wants to find the sum of the length after 10 throws, we are just going to add the lengths above. So the answer would be this:  9.71752475. To round this off to the nearest hundredth, the answer would be 9.72. Hope this helps.

8+—3(6+—6a) help please
LenKa [72]
We know that:

(+)+(-)=(-)

and:

(-)*(+)=(-)

8+(-3)[6+(-6a)]=8+(-3)*6+(-3)*(-6a)=8-18+18a=(-10)+18a

if you have solve for a then:

(-10)+18a=0
18a=10
a= \frac{10}{18}
a=\frac{5}{9}

A bag contains 4 red and 6 green gumballs. if you select 5 of them without looking, how many ways can you get exactly 3 red or e
marusya05 [52]
This is a combination problem. The approach to this is by using the nCr method, where n is the number of total objects and r is the number of success. For example, if you want to get 3 red out of the total 4, then that would be 4C3. That means,

4C3 = 4!/3!(4 - 3)! = 4 ways

If you want to get 2 green out of the total 6, then that would be 6C2. That means,

6C2 = 6!/2!(6-2)! = 15 ways

Therefore, there are a total of 4+15 = <em>19 ways</em>.
