There are 14 times in the table.  Add up all 14 times, and divide the sum by 14.  The result is the "mean 100-meter sprint time," assuming that you've rounded this off to the nearest tenth of a second.

The total amount spent by some number of people on clothing and footwear In the years 2000-2009 can be modeled by the quadratic
FinnZ [79.3K]

For this problem, we are given a quadratic equation that models the total amount spent on clothing and footwear in the years 2000-2009. We need to use the model to determine the maximum amount spent during the period.

The equation is shown below:

f(x)=-4.462x^2+71.54x+97.44

Since the leading term is negative, the vertex of this function will represent an absolute maximum value. Therefore we can determine the vertex to answer the problem, the vertex's coordinates are given below:

\begin{gathered} x_{max}=\frac{-b}{2a}\\ \\ y_{max}=f(x_{max}) \end{gathered}

Then we have:

\begin{gathered} x_{max}=\frac{-71.54}{2\cdot(-4.462)}=8.017\\ \\ y_{max}=-4.462\cdot(8.017)^2+71.54\cdot(8.017)+97.44=384.2 \end{gathered}

In the year 2008, 384 billion was spent on clothing and footwear.
