Answer:
The fractional probability of getting 2 heads is 1/4.
Answer:
Step-by-step explanation:
We are to show that 
<u>Proof:</u>
From trigonometry identity;


From trigonometry, 2sinAcosA = Sin2A

Also note that sin(B-C) = sinBcosC - cosBsinC
sin420cos140 - cos420sin140 = sin(420-140)
The resulting equation becomes;

= 
Answer: c
given volume is 125 cc
cube root of 125 is 5
aka 5×5×5=125
and 6×5×5=150
hence answer is c
The answer is 4x-8+4y i think?
