Answer:

a) Quantitative; discrete  

b) Qualitative

c)  Quantitative; continuous                        

Step-by-step explanation:

Quantitative and Qualitative:

  • Qualitative variables are the non-parametric variables.
  • Quantitative variables are the variables whose values are expressed in the form of number.
  • Qualitative is information about a variable where as quantitative describes the variable with the help of values.

Discrete and Continuous:

  • Quantitative variables whose values are expressed in the form of whole numbers are discrete variable.
  • Discrete variable cannot take all the values of an interval. They are counted not measured.
  • Quantitative variable whose values can be expressed in the form of decimals are continuous variable.
  • Continuous variable take all the values within interval. They are measured not counted.

a. Points scored in a football game.

Since the points are expressed in numerical. Thus, they are quantitative variable. Since points are always expressed in whole numbers and are always counted it is a discrete variable.

b. Racial composition of a high school classroom

This will include the categorical values and not expressed as numerical. Thus, it is qualitative variable.

c. Heights of 15-year-olds.

These values will be expressed with the help of numerical and can take any value within an interval. Also, height is always measured and not counted. Thus it is a continuous variable.

1. Geometric Sequence

2. a_n = a_{n-1} * 3

3. a_n = 6 * (3)^{n-1}

Step-by-step explanation:

Given sequence is:

6, 18, 54, 162,....

Here

a_1 =6\\a_2 = 18\\a_3 = 54

(a) Is this an arithmetic or geometric sequence?

We can see that the difference between the terms is not same so it cannot be an arithmetic sequence.

We have to check for common ratio (ratio between consecutive terms of a sequence) denoted by r

r = \frac{a_2}{a_1} = \frac{18}{6}= 3\\r = \frac{a_3}{a_2} = \frac{54}{18} = 3

As the common ratio is same, the given sequence is a geometric sequence.

(b) How can you find the next number in the sequence?

Recursive formulas are used to find the next number in sequence using previous term

Recursive formula for a geometric sequence is given by:

a_n = a_{n-1} * r

In case of given sequence,

a_n = a_{n-1} * 3

So to find the 5th term

a_5 = a_4*3\\a_5 = 162*3\\a_5 = 486

(c) Give the rule you would use to find the 20th week.

In order to find the pushups for 20th week, explicit formul for sequence will be used.

The general form of explicit formula is given by:

a_n = a_1 * r^{n-1}

Putting the values of a_1 and r

a_n = 6 * (3)^{n-1}

Hence,

1. Geometric Sequence

2. a_n = a_{n-1} * 3

3. a_n = 6 * (3)^{n-1}
