To find the equation of a trend line, It is important to find the X axis and Y axis, Once x axis and y axis  is found if there is an association between x axis and y axis, We use linear equation to produce the trend line. Linear regression or algorithm called as OLS (Ordinary least square). Y= mx +c

y = dependent variable, x = independent variable , constant = c , m  = y2-y1/x2-x1.

Step-by-step explanation:

  • Scatter plot is to find association of two different variable.
  • Trend line is the equation between xaxis and y axis.
  • Prediction is best way to form equation.
  • Linear regression y=mx +c
  • Equation helps in predictive modelling between next best form.
  • Y is a dependent variable or example sales.
  • X can be n number of variable involved in the association rule.
  • Linear regression is starting phase of data analysis.
  • C = constant there is a certain point, where system has been started.
  • Stock market did not start from 0 it started at a certain point.

Answer: To determine the equation, identify two points on the trend line. Calculate the slope between the two points. Use the slope-intercept form with the slope and one of the points from the line to determine the y-intercept. Write the equation with the slope and the y-intercept.

Michael hires a cab that charges a fare of $0.50 per mile, plus an initial charge of $2. Jason hires a cab that charges a fare o
Vanyuwa [196]

use reapeted addition and keep adding +$0.50 until you get $4.00 for it to be equal with Jason's total which was $4.00

so it will be at 3 miles.

or just multiply micheals total by 3.:) hope it helped!!

What is the standard form for the quadratic function? g(x)=(x+1)2−2 g(x)=x2−1 g(x)=x2−2x−4 g(x)=x2+2x−1 g(x)=x2−3
serious [3.7K]

Answer:

x^2 + 2x - 1

Step-by-step explanation:

g(x)=(x+1)2−2 would be a quadratic if you'd write it like this:  g(x)=(x+1)^2−2.

This expands to g(x) = x^2 + 2x + 1 - 2  =  x^2 + 2x - 1

How many five-digit integers (integers from 10,000 through 99,999) are divisible by 5?
lukranit [14]
Okay to solve this problem you would simply do this solution. It took me a minute, haven't had to do integers in a while. :D

From 10,000 to 99,999 the numbers divisible by 5 ends in 0 or 5.
The first (most significant) digit can be any of nine from 1 to 9.
The 2nd digit can be any of 10.
The 3rd digit can be any of 10.
The 4th digit can be any of 10.
The 5th digit can be either of 2.

<span>That's 9(10)(10)(10)2=18,000
</span>
I hope this helps.
