Consider a bag containing four red marbles, three green ones, one transparent one, three yellow ones, and three orange ones.

Allisa [31]

Answer:

Step-by-step explanation:

Given,

Number of red marble = 4
number of green marble = 3
number of transparent marble = 1
number of yellow marble = 3
number of orange marble = 3

Total number of marble except red and green = 3 +3+1

= 7

So, the total number of possible sets of five marbles such that none of them are green or red can be given by

$n\ =\ ^7C_5$

$=\ \dfrac{7!}{(7-5)!.5!}$

$=\ \dfrac{7!}{5!.2!}$

$=\ \dfrac{42}{2}$

= 21

So, the required number of possible sets are 21.

CONVERGENT AND DIVERGENT SERIES PLEASE HELP

drek231 [11]

Answer:

Step-by-step explanation:

We are given a series

We can see that numerators are same

and denominators are

49 , 64 , 81 , .....

so,

7^2 , 8^2 , 9^2

We can write nth term

$a_n=(n+7)^2$

so, we can write as

$\sum _{n=0}^{\infty }\:\frac{1}{\left(n+7\right)^2}$

We can use p-series test

$\frac{1}{n^p}$

we can compare

and we get

$p=2>1$

So, this series is convergent

this is FALSE
