Answer:
C 34 cm
Step-by-step explanation:
Area = L x W

Perimeter = 2 ( L+W) = 2 ( 8+ 9) = 34 cm
Answer:
0.3257
Step-by-step explanation:
Given an approximately normal distribution:
Z = (x - mean) / standard deviation
Mean = 496 ; Standard deviation = 110
For :
P(x > 545.7)
We obtain the standardized, Z score
Z = (545.7 - 496) / 110
Z = 49.7 / 110
Z = 0.4518
Hence, using the Z distribution table :
P(Z > 0.4518) = 1 - P(Z < 0.4518)
P(Z > 0.4518) = 1 - 0.67429
P(Z > 0.4518) = 0.32571
Answer:
95% chance
Step-by-step explanation:
10+6+3+1=20
1/20=0.05 or 5%
5% chance of the marble being green
100%-5%=95%
