First, Delete these brackets on the right side:
Left side and right side are equal, so each parameters have to be equal. Next to "x^2" you've got parameters "6" and "3n". So:
3n=6 /:3
n=3Free terms are "6" and "3m", so:
3m=6 /:3
m=2Next to "x" you've got "b" and "9+nm" . We know, that m=2 and n=3 so:
b= 9+nm
b=9+2*3=9+6
So
b=15
Answer:
The percentage of the variability in plant weight is NOT explained by height is
%
Step-by-step explanation:
From the question we are told that
The correlation between height and weight is 
Generally the R-Squared between height and weight is mathematically represented as
substituting values
This R-Squared tells us the percentage of plant weight is accounted by height
and from the calculation we see that it is 56.3%
Now the percentage of plant weight that is not accounted by height is
%
sin = 3/7
1 = sin²0 + cos²0
cos²0 = 1 - 9/49
cos²0 = 40/49
cos0 = √(40) / 7
since its in Quadrant 2 the sin is positive and cos is negative
cos0 = - √(40) / 7
Answer:
Step-by-step explanation:
He has a raise of $400 at the end of each year, the we have to find how much is the total amount raised during the 15 years, then:
The during the 25 years he has a total raised of $6000 as the salary during the first years was $3000, the salary during the 15th year is:
If x represents the mass of 1 ball in kg, then the balance shows ...
... 6x = x + 9 kg
... 5x = 9 kg
Then 6x is ...
... (6/5)·5x = (6/5)·9 kg = 10.8 kg
0.8 kg = 0.8·1000 g = 800 g
so 10.8 kg is ...
... D. 10 kg 800 g
