Me for the love of god if i fail i have to repeat the class

given : sin ∅= 4/5 | cos x = -5/13 (∅: quadrant i, x: quadrant ii)

what is:

1. sin(∅+x)

2. cos(∅-x)

3. tan(∅+x)

4. sin2 ∅

5. cos 2x

6. tan2 ∅

7. tan 1/2x

8. sin 3 ∅

The dot plot below shows the number of toys 21 shops sold in an hour: dot plot labeled number of toys sold shows 6 dots over 0, 4 dots over 1, 3 dots over 2, 3 dots over 3, 2 dot over 4 and 3 dots over 9 is the median or the mean a better center for this data and why? median; because the data is not symmetric and there are outliers median; because the data is symmetric and there are no outliers mean; because the data is symmetric and there are no outliers mean; because the data is skewed and there are outliers
