Answer:
None
Step-by-step explanation:
Assuming you mean sides of a right triangle, we can use the Pythagorean theorem (A^2 + B^2 = C^2)
We have A and B, so we can plug those into the equation.
(16)^2 + B^2 = (14)^2
(16)^2 is 256 and (14)^2 is 196. Plug those in.
256 + B^2 = 196
Get rid of the 256 by subtracting.
B^2 = 196 - 256
B^2 = -60
√B^2 = √-60
You can't take the square root of a negative number, so the solution is not possible. We can confirm because C cannot be bigger than A or B.
Answer:
d). 14 and 240
Step-by-step explanation:
According to the Question,
- Given that, The regression model involving 14 independent variables and 255 observations
We need to find out the numerator and denominator freedom degrees
,
k = 14 regression variable
= n - k - 1
= 255 - 14 - 1
= 240 residuals
df=14,240
-
Now The degree of freedom for F-critical is
F_{k,n-k-1}=F_{14,240}
So, The df of the numerator is 14 and df of the denominator is 240
Answer:
12
Step-by-step explanation:
12 - 4 = 8
The square of 8 is 64
The equivalent equation is x² + 20x = -102
<h3>
Simplification of quadratic equation</h3>
The equivalent equation can be obtained by factorizing or simplifying the given quadratic equation as shown below;
x² + 20x + 81 = -21
<em>collect similar terms together</em>
x² + 20x + 81 + 21 = 0
x² + 20x + 102 = 0
The equation can also be written as x² + 20x = -102
Thus, the equivalent equation is x² + 20x = -102
