The answer is 40 degrees.
Answer:
Closest standard deviation of W = 4.11
Step-by-step explanation:
Randomly selected workers = n =300
Probability of workers arriving between 6:45 to 7:00 A.M = p = 6% = 0.06
According to binomial distribution:
mean = μ = n.p
= 300(0.06) = 18
variance = σ² = n.p(1-p)
= (300)(0.06)(1-0.06)
= (18)(0.94)
= 16.92
standard deviation = σ = 4.11
Answer:
3/7
Step-by-step explanation:
Probability a turban is lent = total number of turbans lent / total number of hats lent
total number of hats lent = 6 + 3 + 3 + 2 = 14
6/14
To transform to the simplest form. divide both the numerator and the denominator by 2= 3/7
