The statistical questions are:
- On average, how many books does each person in the United States read each year
- Which book was read most by students in the class, this summer
The non-statistical questions are:
- How many acts are there in the play Romeo and Juliet
- How many books are in the class right not
<h3>How to categorize the questions?</h3>
As a general rule, questions whose answers can be determined using a single data point are non-statistical questions.
Using the above rule, we have the non-statistical questions to be:
- How many acts are there in the play Romeo and Juliet
- How many books are in the class right not
As a general rule, questions whose answers cannot be determined using a single data point are statistical questions.
Using the above rule, we have the statistical questions to be:

Answer:
108
Step-by-step explanation:
The tangent- tangent angle XYZ is
∠XYZ = 0.5( arc ZX - arc XZ), that is
72 = 0.5(360 - x - x)
72 = 0.5(360 - 2x) = 180 - x ( add x to both sides )
72 + x = 180 ( subtract 72 from both sides )
x = 108

Tip: $3.70
Total: $28.49
Step-by-step explanation:
1. Finding the tip:
a. tip = total cost * rate of tip
or you could do it as a proportion, which would be
b. tip percent/100 = tip/total cost
use cross products to get the tip, then add it to the total price.
I hope this helped.
