here is the solution to the question
We develop the ratio between the number of milliliters present in 1 tablespoon and that is,
15 mL: 1 tablespoon
We let x be the number of millileter in 3 tbsp and it can be determined through the equation below.
x = 3 tbsp x (15 mL/ 1 tbsp) = 45 mL
Therefore, there are 45 mL in 3 tbsp.
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.
Neither of them are positive because a negative times a positive is always a negative.
now if there is a typo, and these are supposed to be added/subtracted, then that is a different story
