(8/13+4/13)+(-6+8) < first one
(8/13+4/13)+(-6+8) and then you add the terms
Answer: y=2/3x+3
*Remember the original equation in slope-intercept form*
y=mx+b
*label that with what each letter stands for*
m=slope/rate of change
x=variable
b=y-intercept
*Substitute this information into the equation
y=2/3x+3

Answer:
0.940
Step-by-step explanation:
Given the data:
Age in years(X) _____Height(Y)
7 _________ 47.3
8 _________48.8
5 __________41.3
8 _________ 50.4
8 ___________51
7 __________47.1
7 __________46.9
7 ___________48
9 __________51.2
8 __________51.2
5 __________40.3
8 __________48.9
6 __________45.2
5 __________41.9
8 __________49.6
The proportion of Variation explained by the line of best fit in a regression model can be determined by calculating the Coefficient of determination (R²) of the model.
Using the online R² calculator, the variation in the sample values of height which is estimated by the model is 0.9696² = 0.94012416.
Hence about 0.94 or 94% variation in sample values of height is estimated by the model while (1 - 0.94 = 0.06 or 6%) is explained by other factors.
