1- biased

2- biased

Step-by-step explanation:

This question is biased because it already determined that a documentary is to boring to watch and an action movie is more exciting to watch.

This question is biased because its asking a health club group which Is targeted to one group of people instead of multiply groups of different people such as a health club and a non-health club.

<span>1. A questionnaire about movie preferences asks if you would rather watch a boring documentary or an exciting action movie.
This is biased.
It is because documentary is labelled "boring" and is put in contrast with an "exciting" action movie. So the questionnaire is trying to get people picks action movie. </span><span />

Find the reference angle given: t= -5π/3.

Elina [12.6K]

Answer:

The reference angle is $\frac{\pi}{3}$

Step-by-step explanation:

The given angle is $t=-\frac{5\pi}{3}$

The reference angle is the acute angle, that a given angle makes with the x-axis.

First let us make a sketch of the given angle. <em>See diagram in attachment.</em>

Let $\theta$ be the reference angle of $t=-\frac{5\pi}{3}$

Then, from the diagram, we need to subtract $\theta$ from $-\frac{5\pi}{3}$ to get to $-2\pi$ .

We can therefore write the following equation and solve for $\theta$ .

$\Rightarrow -\frac{5\pi}{3}-\theta=-2\pi$

We group like terms to get,

$\Rightarrow -\theta=-2\pi +\frac{5\pi}{3}$

We collect LCM to get,

$\Rightarrow -\theta=\frac{-6\pi+5\pi}{3}$

We simplify to get,

$\Rightarrow -\theta=-\frac{\pi}{3}$

We divide through by $-1$

$\theta=\frac{\pi}{3}$ to get,

The correct answer is D.
