This is a sampling technique used when natural groupings are evident in a statistical population. It is often used in marketing research.
3 x 4 x 12 = 144 if you need the volume. Hope this helps! :D
Answer: 5 branches and 16 birds.
Step-by-step explanation:
If the number of birds is B, and the number of branches is N.
First we have the equation:
B = 3*N + 1
(3 birds per branch + 1 that was flying around)
for the second equation we have:
B = 4*(N - 1)
(4 birds per branch, but one branch had no birds on it, so there are N -1 branches used)
now we can write:
3*N + 1 = 4*(N - 1)
3*N + 1 = 4*N - 4
4 + 1 = 4*N - 3*N
5 = N
So we had 5 branches, now we can replace it in one of the equations and find the number of birds.
B = 3*N + 1 = 3*5 + 1 = 16
The answers to the questions
Answer:
C) 4/3
TanX = 4/3
Step-by-step explanation:
From SohCahToa, we understand the Trigonometric relationship between angles.
(sin) Soh = Opposite / Hypotenuse
(cos) Cah = Adjacent / Hypotenuse
Tan (Toa) = Opposite / Hypotenuse
From the question:
Considering angle X, the ;
Opposite = 32
Adjacent = 24
Hypotenuse= 40
TanX = Opposite / Adjacent
= 32/24
We divide through by 8
TanX = 4/3
