1 answer:
Answer:
5.4 numbers of purple beads and 12.6 numbers of silver beads.
Step-by-step explanation:
Arlene makes a necklace using 14 purple beads for every 6 silver beads. So, she uses purple and silver beads in the ratio 14 : 6 = 7 : 3.
Now, the necklace contains 18 beads, then in the ratio 7 : 3, there will be numbers of purple beads and (18 - 5.4) = 12.6 numbers of silver beads. (Answer)

Given:
The composition of functions is G(F(y)).
To find:
The independent variable of G(F(y)).
Solution:
Independent variable is the variable whose value independent from other variable. It means the value of independent variables is not depend on the other variable.
We know that G(F(y)) can be written as
Here, the value of function G depends on F(y) and the value of F(y) depend on variable y. But value of y does not depend on any variable. So, y is the independent variable of G(F(y)).
Therefore, the correct option is C.
