Answer:

The best fit line is a regression line explaining relationship between dependent & independent variables, minimising the residual differences between observed values & actual values of dependent variable.

Step-by-step explanation:

Regression is a statistical process that explains relationship between dependent variable & independent variable(s). Scatter plot depicts the regression relationship between the variables in a graphical form.

Scatterplot showing snowfall measured in inches : is a graphical depiction of - regression relationship between snowfall as a dependent variable with its explanatory (independent) variables ; like temperature, humidity , other climate & weather factors etc.

The line of best fit would be a regression line (scatterplot), which describes the relationship of snowfall with its above mentioned explanatory variables, in such a way that the estimated value of snowfall is closest possible tothe actual values of snowfall (i.e their difference is minimum).

Select the correct answer. Consider these three numbers written in scientific notation: 6. 5 × 103, 5. 5 × 105, and 1. 1 × 103.

Scientific notation uses expression which gives easy access of order. The greatest number is 5.5 \times 10^5 .It is greater by smallest number by 500  times.

<h3>How to convert a number to scientific notation?</h3>

It is usually of the form a.bc.. \times 10^kexponent of 10 starts)

(we have 1 ≤ |a| < 10 ) (where |a| is magnitude of a without sign)

This notation is used to get some idea of how large or small a number is in terms of power of 10.

<h3>What are some basic properties of exponentiation?</h3>

If we have a^bbase and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\ a^b \times a^c = a^{b+c}

The given numbers are:

  • First number = 6.5 \times 10^3 = 6500
  • Second number = 5.5 \times 10^5 = 550000
  • Third number = 1.1 \times 10^3 = 1100

The smallest number is 1,100 and greatest is 550,000

Getting the division to get to know how many times the greatest number is larger than the smallest number, we get:

\dfrac{5.5 \times  10^5}{1.1 \times 10^3} = \dfrac{5.5 \times 10^{5-3}}{1.1} = \dfrac{5.5}{1.1} \times 10^2 = 5 \times 10^2 = 500

Thus, it is found that greatest number is 5.5 \times 10^5 . It is greater by smallest number by 500  times.
