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:
She had 9 gift bags
Step-by-step explanation:
if we divide 63 by 7 we get 9
now, if we take 9 and call that our bags that means there will be 7 party favors in each bag
So whe have
that is paid to the boss.
The boss won 2,176.10 this month.
So our equation would end as...
We solve what can be solved...
0.47=\frac{2,176}{x}
Then we leave our unknown value alone...
0.47x=2,176
x=\frac{2,176}{0.47}
Last we solve...
x= 4,629.79
x≈4,630
So the answer is A.
