A survey of 250 lobster fishermen found out they catch an alarm fridge of 32.0 pounds of lobster birthday with a standard deviation of 4.0 pounds if a random sample of 36 lobster lobster Fisherman and selected what is the probability that they are average catch is less than 31.5 pounds assume the distribution of the weights of lobster is normal

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
