Answer:
the answer is A on edge i took the test .
Step-by-step explanation:
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:
C
Step-by-step explanation:
only a dilation would make the figures not congruent/similar
The Answer is
D) 31
Because 9x+13,
9(2)+13,
18+13,
31
Answer:
4x+1
Step-by-step explanation:
The area is 12x2 + 3x in
The length is 3x
Formula is A=L*B
12x2 + 3x=3x*B
Divide both side by 3x
12x2+3x divide by 3x=B
4x+1=B
The express for the width is 4x+1
