Answer:

Step-by-step explanation:

You can pick a point, such as the vertex at (2, -3) on f(x) and see which of the transformations gives you a point on the graph of g(x).

You will find that g(x) represents a vertical scaling by a factor of 1/3, so ...

g(x) = 1/3·f(x)

The point (2, -3) on f(x) corresponds to the point (2, -1) on g(x).

A box contains 2 dozen pairs of contact lenses ,of which 8 pairs are tinted. A pair of contact lenses is drawn at random from th

tia_tia [17]

Answer:

$\dfrac{2}{3}.$

Step-by-step explanation:

It is given that a box contains 2 dozen pairs of contact lenses ,of which 8 pairs are tinted.

1 dozen = 12 units

Total pairs of contact lenses $=2\times 12 = 24$

Tinted pairs of contact lenses = 8

Pairs of contact lenses not tinted = 24 - 8 = 16

If a pair of contact lenses is drawn at random from the box, then we need to find the probability that it is not tinted.

$P(\text{Not tinted})=\dfrac{\text{Pairs of contact lenses not tinted}}{\text{Total pairs of contact lenses}}$

$P(\text{Not tinted})=\dfrac{16}{24}$

$P(\text{Not tinted})=\dfrac{2}{3}$

Therefore, the required probability is $\dfrac{2}{3}.$
