Answer:

4

Step-by-step explanation:

With either pass you have to add $20 per day, so you can ignore that

Assuming he goes "x" days to sky you can calculate the days he has to go to equal $300.

300 = 79x

x = 300/79 = 3.8 days

If he goes 4 days to sky it costs 316, so in that case its cheaper to buy the season pass

How do you categorize each of these questions as one of these types
Sindrei [870]

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:

  • 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

Also, both statistical questions are numerical

In the diagram of circle P, m XYZ is 72°. What is the value
mylen [45]

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

or you could do it as a proportion, which would be
