According to the graph it can be inferred that the percentage of people for each transmission preference is relatively the same for left-handed and right-handed people (option D)

<h3>How to read the graph?</h3>

The graph shows two bars representing left-handed respondents and right-handed respondents. In the bars there is a blue division that represents the percentage of respondents who prefer manual transmission.

In both cases, the number of people is similar for both variables (manual and automatic) because for every 100 people surveyed, about 20 people prefer manual transmission regardless of whether they are right-handed or left-handed.

Answer: 63°

<u>Step-by-step explanation:</u>

Since BD is the diameter, then arc BCD = 180°

Given that arc BC = 54°, then arc CD = 180° - 54° = 126°

∠DBC is an intercepted angle -> DBC = half of arc CD

\angle DBC=\bigg(\dfrac{1}{2}\bigg)126^o\quad =\large\boxed{63^o}

=x^2-4x-4x+16
=x^2-8x+16
it’s +16, not negative. he forgot that when you add two negatives together, it becomes positive.
