Answer:
Yes
Step-by-step explanation:
Adding to both sides of the equation will keep both sides equal
Answer:
56$
Step-by-step explanation:
40% of 20 = 8 - 20 = 12 times 3 = 36+20=56
The answer is 12.
6+4 = 10
10 x 3 = 30
30 - 6 = 24
24 / 2 = 12
Answer:
Step-by-step explanation:
sin(x+y) = sin(x)cos(y) + sin(y)cos(x)
sin(x-y) = sin(x)cos(y) - sin(y)cos(x)
Sin(x+y)sin(x-y) = (sin(x)cos(y) + sin(y)cos(x))(sin(x)cos(y) - sin(y)cos(x))
= sin^2(x)cos^2(y) - sin^2(y)cos^2(x)
= sin^2(x)(1-sin^2(y)) - sin^2(y)(1-sin^2(x))
= sin^2(x) - sin^2(x)sin^2(y) - sin^2(y) + sin^2(x)sin^2(y)
= sin^2(x) - sin^2(y)
So L.H.S=R.H.S
Hence proved
p-value is a measure of the probability that an observed difference could have occurred just by random chance.
