Answer:
2520
Step-by-step explanation:
LCM(4, 7, 8, 9, 10, 12) = 2520
Choosing 3 cards from a deck of 52 cards:
In short, how many combinations there are in choosing 3 cards among 52 ?
⁵²C₃ = (52!) / (3!)(49!) → 22,100 combinations
Given:
Northern Florida: 2,000 patients ; 64% experienced flulike symptoms during December
Southern Florida: 3,000 patients ; 54% experienced flulike symptoms during December
Standard error = √[p(1-p)/n]
NF = √[0.64(1-0.64)/2000] = √[(0.64*0.36)/2000] = 0.0107 or 1.07%
SF = <span>√[0.54(1-0.54)/3000] = √[(0.54*0.46)/3000] = 0.0091 or 0.91%
smallest margin of error for a 95% confidence interval
NF: Em </span>≈ 0.98/√2,000 = 0.98/44.72 = 0.0219 or 2.19%
<span>SF: Em </span>≈ 0.98/√3,000 = 0.98/54.77 = 0.0178 or 1.78%

49=16+x^2
x^2= 33
x= square root of 33
