The line of the best fit is y = 2100x -4166040 and the number of bottles is, 86460 which expect to sell in 2025

<h3>What is the line of best fit?</h3>

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

We have data shown in the table:

To find the line of best fit, we will calculate its slope and y-intercept.

We know the slope is given by:

\rm m = \dfrac{n\sum xy-\sum x \sum y}{n \sum x^2 - (\sum x)^2}   where n = 5

After calculating, we get,

\rm n\sum xy-\sum x \sum y = 105000  and

\rm n \sum x^2 - (\sum x)^2 = 50

m = 105000/50 = 2100

For y-intercept b:

\rm b = \dfrac{\sum y -m \sum x}{n}

After calculating:

b = -4166040

The line becomes:

y = 2100x -4166040

If x = 2025 put this value in the line, we get:

y = 86460

Thus, the line of the best fit is y = 2100x -4166040 and the number of bottles is, 86460 which expect to sell in 2025

If f(x) = 3x2 - 2x + 5, find f(-2)<br> A) -27 <br> B) -11 <br> C) -3 <br> D) 21
Digiron [165]

Answer:

D

Step-by-step explanation:

You have to be careful that you treat 21 as special. It is the only positive number. As you do the problem, keep an eye on 21.

f(-2) = 3x^2 - 2x + 5                Put -2 wherever you see an x

f(-2) = 3(-2)^2 - 2(-2) + 5         Calculate the first term.    

f(-2) = 3(4) - 2(-2) + 5              Remove the brackets of the second term

f(-2) = 12 + 4 + 5                     Combine

f(-2) = 21
