Step-by-step explanation:
for every 2 girls there is 1 boy.
The answer to your question is 114
Answer:
The answer is a. cos2x - sin2x - sin x. Use the rule: cos2x = (cos^2)x - (sin^2)x. So, substitute cos2x in the expression: cos2x - sinx = ((cos^2)x - (sin^2)x) - sinx = (cos^2)x - (sin^2)x - sinx. Therefore, choice a. is correct choice.
Well there are no even numbers in there, so the probability of taking one out must be 0
Perimeter is 2L x 2W or L + L + W + W
A) 12(2) + 24(2) = 72
B) 18(2) + 36(2) = 108
C) 27(2) + 54(2) = 162
D) 36(2) + 36(2) = 144 (and one side is not even twice the length of the other)
Answer: B
