Answer:
A is your answer
Step-by-step explanation:
<span>if 35% or 0.35 say no, to compute the probability that at least one of 7 </span>called a talk show while under the influence of peer pressure <span> is (1-0.35)^7 and subtract it from . This is the same as at least 1 has </span><span>called a talk show while under the influence of peer pressure
</span><span>1 - (1 - 0.35)^7 = 0.95
</span>
I believe that it's (1,3)

Answer:
1/8
Step-by-step explanation:
sin²(π/8) − cos⁴(3π/8)
Use power reduction formulas:
1/2 (1 − cos(2×π/8)) − 1/8 (3 + 4 cos(2×3π/8) + cos(4×3π/8))
Simplify:
1/2 (1 − cos(π/4)) − 1/8 (3 + 4 cos(3π/4) + cos(3π/2))
1/2 (1 − √2/2) − 1/8 (3 + 4 (-√2/2) + 0)
1/2 − √2/4 − 1/8 (3 − 2√2)
1/2 − √2/4 − 3/8 +√2/4
1/2 − 3/8
1/8
