Answer:

Step-by-step explanation:
We want to simplify:

We convert to improper fraction to get:

We now deal with the parenthesis by multiplying with the reciprocal of 2.

This gives:

We multiply to get:

This simplfies to:

We write as mixed number

Answer:
Possible answer maybe: -2<b<6
Answer:
The graph is misleading because the vertical scale is not even. It goes from 0 to 15 and then thereafter the scale reverts to a scale of 5.
This is misleading because had the graph gone in a scale of 5 from the get go, the number of people who thought 3-4 episodes were too much would have looked higher in the graph as they seem to comprise of about 5% of the sample population.
The scale should begin at 0 and then go like 5 ⇒ 10 ⇒ 15 ⇒ 20 ⇒ 25 ⇒ 30
5.21 + 0.6 - (0.27 / 3) I assume this is the right equation
5.21 + 0.6 = 5.81
0.27 / 3 = 0.09
5.81 - 0.09 = 5.72
