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:Y=30x
Step-by-step explanation:
90-0=90
9-6=3
90/3=30
y=30x
Answer:
Look at the names of the prisms above. Each type of prism is named after its base. In the figure on the left, the base is a rectangle, so it is called a rectangular prism. In the middle, the base is a triangle, so the shape is a triangular prism.

Answer:
<em>Cost paid daily when using the motorcycle: $37,</em>
<em>Cost paid for each kilometer driven in the motorcycle: $ 0.23 </em>
Step-by-step explanation:
<em>~ Let us first formulate the equations, provided x ⇒ cost paid daily when using the motorcycle, and y ⇒ cost paid for each kilometer driven in the motorcycle ~</em>
8x + 650y = 445.5, and 12x + 920y = 655.6
<em>Now let us solve this equation through elimination, by multiplying the first equation by 3, and the second by -2:</em>
3 ( 8x + 650y = 445.5 ) ⇒ 24x + 1950y = 1336.5 ⇒ 110y = 25.3
+ -2 ( 12x + 920y = 655.6 ) + -24x - 1840y = - 1311.2 <em>y = 0.23</em>
<em>Now we can substitute this value of y into the first equation as to solve for x: </em>8x + 650 ( 0.23 ) = 445.5, 8x = 296, <em>x = 37</em>
<em>* Cost paid daily when using the motorcycle: $37,</em>
<em>Cost paid for each kilometer driven in the motorcycle: $ 0.23 *</em>
He had 44 books before the purchases because 12% of 50 is 6 and 6-50 is 44
