Step-by-step explanation:
z-score of X = 6150
z-score of X = 6350
P(X<6150) + P(X>6350)
=P(z<-0.4) + P(z>-0.4)
=0.3446+0.3446
=0.6892
Answer:
Area of triangle = ½(12)(8) = 48 m²
Area of semicircle = ½π(4²) = 8π
Α = 48 + 8π m² ≈ 73.132741... m²
Not seeing an option that is reasonably close.
768
this is the answer
A=21°;B=53°;C=106°
I hope it helps.
