a bag containes 8 white marbels and 48 green marbles. If a representative sample contains 2 white marblesthen how many green marbles would you expect it to contain?

12

Step-by-step explanation:

8 white marbles and 48 marbles

each sample contains 2 white

so first

8 divide 2 = 4

then second

48 divide 4=  12

hope this helps

Step-by-step explanation:

sin²β + sin²β×tan²β = tan²β

sin²β( 1 + tan²β ) = tan²β

~~~~~~~~~~~~~~~~

sin²β + cos²β = 1  

+ = ⇒ tan²β + 1 = sec²β ⇔ 1 + tan²β = sec²β

~~~~~~~~~~~~~~

1 + tan²β =

L.H. = sin²β ( ) = tan²β

R.H. = tan²β
