Small table and small figure next to each other

Question

Any tips on how to put these two together (see image upload). Current code:

\documentclass[
    11pt,english, onehalfspacing, nolistspacing, liststotoc, headsepline, oneside, chapterinoneline, reqno, a4paper, toctotoc]{report}

\usepackage[utf8]{inputenc} \usepackage[T1]{fontenc}

  \begin{table}[!htb] \centering
        \small \caption{}
        \begin{tabular}{@{}ll@{}}
        \toprule\toprule
        & Individual variance\\ \midrule
        AAPL & 0.76 \\
        BA & 0.55 \\
        CBRE & 0.60 \\
        CMG & 0.91 \\
        DIS & 0.58 \\
        GOLD & \cellcolor{red!25}1.00 \\
        IBM & 0.64 \\
        KO & 0.69 \\
        MD & \cellcolor{green!25}0.0050 \\
        MMM & 0.43 \\
        NKE & 0.72 \\ \midrule \midrule
        \end{tabular}
        \end{table} \label{tab 1.5}
        %
        \begin{figure}[H]
            \centering
            \includegraphics[width=.5\linewidth]{Figures/biplot_factoran.eps}
            \caption{Biplot where $\mbox{FA}_1$ is on the $x$-axis and $\mbox{FA}_2$ is on the $y$-axis}
        \end{figure}

\documentclass{article}
\usepackage{amsmath}
\usepackage{colortbl}
\usepackage{xcolor}
\usepackage{booktabs}
\usepackage{graphicx}
\usepackage{adjustbox}
\usepackage{caption}
\begin{document}

An alternative solution using the floatrow package:

\documentclass{report}

\usepackage[utf8]{inputenc} 
\usepackage[T1]{fontenc}
\usepackage{booktabs}
\usepackage[table]{xcolor}
\usepackage[demo]{graphicx}
\usepackage{floatrow}

\begin{document}

\begin{table}
  \CenterFloatBoxes
  \begin{floatrow}[2]
    \ttabbox[\FBwidth]{%
      \small 
        \begin{tabular}{@{}ll@{}}
        \toprule\toprule
        & Individual variance\\ \midrule
        AAPL & 0.76 \\
        BA & 0.55 \\
        CBRE & 0.60 \\
        CMG & 0.91 \\
        DIS & 0.58 \\
        GOLD & \cellcolor{red!25}1.00 \\
        IBM & 0.64 \\
        KO & 0.69 \\
        MD & \cellcolor{green!25}0.0050 \\
        MMM & 0.43 \\
        NKE & 0.72 \\ \midrule \midrule
        \end{tabular}}{%
      \caption{}}
  \killfloatstyle
    \ffigbox[0.5\textwidth]{%
        \centering
        \includegraphics[width=\linewidth]{Figures/biplot_factoran.eps}}{%
        \caption{Biplot where $\mbox{FA}_1$ is on the $x$-axis and $\mbox{FA}_2$ is on the $y$-axis}}
  \end{floatrow}
\end{table}

\end{document}

Yet another option is to switch to the excellent KOMA-Script bundle and use the report class scrreprt. It has all the necessary options built in. On page 133 in the manual, it islisted code that does exactly what you are asking for. Here is the code adapted to your MWE:

\documentclass{scrreprt}
\usepackage[utf8]{inputenc} 
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage[table]{xcolor}
\usepackage{booktabs}
\usepackage{graphicx}

\begin{document}

\begin{figure}
\begin{minipage}{.5\linewidth}
\centering
\includegraphics[width=\linewidth]{biplot_factoran}
\caption{Biplot where $\mbox{FA}_1$ is on the $x$-axis and $\mbox{FA}_2$ is on the $y$-axis}\label{fig:rechteck}
\end{minipage}%
\begin{minipage}{.5\linewidth}
\centering\small
\captionaboveof{table}{}
\label{tab:rechteck}
        \begin{tabular}{@{}ll@{}}
        \toprule
        & Individual variance\\ \midrule
        AAPL & 0.76 \\
        BA & 0.55 \\
        CBRE & 0.60 \\
        CMG & 0.91 \\
        DIS & 0.58 \\
        GOLD & \cellcolor{red!25}1.00 \\
        IBM & 0.64 \\
        KO & 0.69 \\
        MD & \cellcolor{green!25}0.0050 \\
        MMM & 0.43 \\
        NKE & 0.72 \\ \bottomrule
\end{tabular}

\end{minipage}
\end{figure}
\end{document}

Giving the output:
