Aforester counted the number of limbs on a 2-year-old tree to be 21. what type of data is 21?

a) quantitative data

b) categorical data

c) continuous data

Here 21 is a discrete number, hence, it is a quantitative data.

Step-by-step explanation:

Quantitative data is that data which gives information about quantities. The information can be written in numerical forms. Like a person's height, number of students in a class etc.

Categorical data divided the information under different categories like the race and sex of person.

Continuous data gives values within a complete range. Like all the students height in a class falls in what range.

Here, we have been given that -a forester counted the number of limbs on a 2-year-old tree to be 21. Here 21 is a discrete number, hence, it is a quantitative data.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
