Identify whether the following variables are numerical or categorical. If numerical, state whether the variable is discrete or c

polet [3.4K]

Solution :

Variables are of two types --- Numerical variable and Categorical variable.

The numerical variable includes measurement and numbers that can be counted. It is also known as quantitative variable. It is of two types --- Discrete and continuous variables.

The categorical variable includes the description of the groups or the things like the type of clothes, color of eyes, etc. that cannot be counted. It is also called qualitative variable. It is of two types -- Nominal variable and Ordinal Variable.

In the context,

a). The percentage or fraction of birds that are infected by a flu is numerical continuous variable.

b). The number of the crimes committed by an individual can be a whole number only and is countable. So it is a Numerical discrete variable.

c). Gender of a person is categorized as male or female. Therefore it is a categorical nominal variable.

d). The logarithm of the body mass is not countable and the body mass can be in decimal form also. So it is a Numerical continuous variable.

e). The different stages of a fruit ripeness can be categorized as fully ripe or unripe i.e. it ranges from unripe fruits to overripe fruits. So it is Categorical ordinal variables.

f). Tree species can be named for the different types of species of the trees. So it is Categorical nominal variable.

g). The petal area of a rose flower cannot be count as the numbers of he petals are not fixed, so it is a Numerical continuous variable.

Answer the following 3 question(s) using the information from the scenario below.

finlep [7]

Answer:

Answer 1: a. Moonlight: C=75n+1000

Riverside: C=50n+1500

Answer 2: c. The solution coordinates are c. (20, 2500)

Answer 3: c. When there are 20 guests attending the price is $2500.

Step-by-step explanation:

Moonlight Hall:

Fixed cost = $1000

Cost per guest = $75

Cost of <em>'n' </em>guests = 75 $\times n$

Total cost of moonlight hall = Fixed cost + Cost of 'n' guests

$\Rightarrow 1000 + 75 \times n$

Riverside Hall:

Fixed cost = $1500

Cost per guest = $50

Cost of <em>'n' </em>guests = 50 $\times n$

Total cost of moonlight hall = Fixed cost + Cost of 'n' guests

$\Rightarrow 1500 + 50 \times n$

Hence, Answer 1:

a. Moonlight: C=75n+1000

Riverside: C=50n+1500

Answer 2: Coordinates of solution:

Option c. (20,2500) satisfies both the equation.

When there are 20 number of guests, the cost of both moonlight and riverside hall comes out to be 2500.

Moonlight Hall cost

$75 \times 20 + 1000\\\Rightarrow \$2500$

Riverside Hall cost

$50 \times 20 + 1500\\\Rightarrow \$2500$

Answer 3: c. When there are 20 guests attending the price is $2500.

The solution is done in Answer 2.

So,

Answer 1: a. Moonlight: C=75n+1000

Riverside: C=50n+1500

Answer 2: c. The solution coordinates are c. (20, 2500)

Answer 3: c. When there are 20 guests attending the price is $2500.
