Answer: 12
Step-by-step explanation: To find the missing length, all we need to do is divide the known length by the area:
44 ÷ 3 2/3
We need to convert this mixed number to an improper fraction. Remember, multiply the whole number by the denominator, then add the numerator to your product (the denominator stays the same):
3 × 3 = 9
9 + 2 = 11
11/3
Now, we divide:
44 ÷ 11/3
Keep the first number, flip the second fraction, and change the sign:
44 × 3/11 = 12 m^2

Answer:
Approximately, 159 men weighs more than 165 pounds and 159 men weighs less than 135 pounds.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 150 pounds
Standard Deviation, σ = 15
We are given that the distribution of weights of 1000 men is a bell shaped distribution that is a normal distribution.
Formula:
P( men weighing more than 165 pounds)
P(x > 165)
Calculation the value from standard normal z table, we have,
