The variable $x$ varies directly as the square of $y$, and $y$ varies directly as the cube of $z$. If $x$ equals $-16$ when $z$
Kisachek [45]

If x varies directly as y^2, then there is some constant a for which

x=ay^2

Similarly, there is some constant b such that

y=bz^3

Given that x=-16 when z=2, we have

\begin{cases}-16=ay^2\\y=8b\end{cases}\implies-16=a(8b)^2\implies ab^2=-\dfrac14

Now when z=\frac12, we get

\begin{cases}x=ay^2\\y=\frac b8\end{cases}\implies x=a\left(\dfrac b8\right)^2=\dfrac{ab^2}{64}=\dfrac{-\frac14}{64}=\boxed{-\dfrac1{256}}

Determine whether the following individual event are independent or dependent. Then find the probability of the combined event.
FromTheMoon [43]

Answer:

dependent and 1.26

Step-by-step explanation:

These two individual events are dependent on each other as first they draw it and then instant they eat two red candy pieces

Now the probability of the combined event is as follows

P(Probability of combined event)  is

= P(Event 1) \times P \frac{Event 2}{Event 1}

= \frac{55}{49} \times \frac{54}{48}

= 1.122 \times 1.125

= 1.26

We simply applied the above formula so that we can get the dependency or independency plus the probability of the combined event
