This is inverse variation. The missing value is: $0.5$ An equation is $xy = 48$

Work Step by Step

The values of y seem to vary inversely with the values of x. Ratio: $1.6 \times 30 =48$ $4.8 \times 10 =48$ The ratio $\frac{y}{x}$ is the same for all data pairs. So this is an inverse variation equation, and $k =48$. The missing value is: $0.5$ since $0.5\times 96 =48$ An equation is $xy = 48$.
