I believe 3b/6a which could reduce to b/3a.
The answer is A I believe
Answer:
D. 3 and 116
Step-by-step explanation:
d.f.N = k - 1 (numerator degrees of freedom) = 4 - 1 = 3
N = 4 × 30 = 120
d.f.D = N - k (denominator degrees of freedom) = 120 - 4 =116
To answer, determine first the length of the arc intercepted by the angle which measures 45°.
Calculate for the circumference of the circle with the equation,
C = 2πr
where C is circumference and r is radius. Substitute the known value for r,
C = 2π(7) = 43.98
Then, multiply the obtained value by the ratio of the angle intercepted and the whole revolution.
Arc = 43.98 x (45°/360°)
Arc = 5.5
The whole perimeter of the sector includes the arc and 2 radii. Hence, the equation for the whole perimeter is,
Perimeter = Arc + 2r
Substituting the values,
Perimeter = (5.5) + 2(7)
Perimeter = 19.50
<em>ANSWER: 19.50 units</em>
Answer:
The proof itself
Step-by-step explanation:
We can define the set of all even numbers as
This is, we can define all even numbers as the set of all the multiples of 
As for the odd numbers, we can always take every even number and sum one to each one. This is
Note that 
(the set of all natural numbers adding the zero) so that for 
then 
Now, given 2 odd numbers 
and 
we can write each one as follows:
And then if we multiply them with each other we obtain:
Then we have that 
is also an odd number as we defined them.
