A large manufacturing company models the number of workers it hired each year after 2010 using the function shown on the graph. Complete the statements describing the situation.
Based on the model, the company hired approximately (300, 350, 200, or 250) workers in 2019. The r² value for this model is 0.56, indicating that this function (is or is not) a good model of the data.

The correct answer is option b.

Explanation:

Quantitative data is a data which gives an information about quantity.These are the information which can be measured and written in the form of numbers.For example, height of a person, number of fingers on the hand etc.

Qualitative data is data which cannot be recorded or observed in the form of numeric data.These types of data are expressed or recorded by the means of simple language description.

One of the example of this from the statement given is:

The Norway spruce grew more slowly than the sycamore every year;

Statement which correctly describes the data is (b):

The bur oak tree’s growth rate averaged 2.5 feet per year; this is a quantitative observation. The average growth rate of a tree is quantitative data which can be expressed in the form of numerals.

Since these pools are similar, they have a scale factor that determines the ratio between each of the sides.

VR = 12

BF = 4

12 / 4 = 3

The scale factor = 3

WZ and TM are similar sides so,

7 * 3 = 21

a = 21
