Answer:
It decreased by 25%
Step-by-step explanation:
8 x .25=2
8 - 2 = 6
Answer:
The slope is 2.25
Step-by-step explanation:
This equation is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 2.25x +2.44
The slope is 2.25
Answer:
the answer is A
Step-by-step explanation:
(9x2 + 10x +4) - (9x2 + 5x -1)
(22+10x) - (17+5x)
5x+5
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.
Answer:
in order for your fraction to equal 3 you need to have 9/3 which will equal 3. so what minus 1 will get you 9? 10 will. x=10
10-1/3
9/3
3=3
