Answer:
Step-by-step explanation:
270= 3*3*3*2*5 = 3³ * 2 * 5
360= 2*2*2*3*3*5 = 3² *2⁴ * 5
Greatest common factor = 2 * 3² * 5
Answer:
a) P(X=41)= 0.0086 = 0.86%
b) P(36≤X≤38)== 0.1215 = 12.15%
c) would be unusual that fewer that 20 murders were cleared because P(X≤20) = 0.000081 =0.0081%
Step-by-step explanation:
if the random variable X= number of cleared murders , then X follows a binomial distribution:
P(X=x)= n!/[(n-x)!*x!]*p^x*(1-p)^(n-x)
where P(X=x)= probability of x cleared murders, n= number of murders selected=50 , p= probability for a murder to be cleared (67%)
therefore
a) P(X=41)=50!/[(50-41)!*41!]*0.67^41*0.33^(50-41)= 0.0086
b) P(36≤X≤38)= P(X≤38) - P(X≤36) = 0.9371- 0.8156 = 0.1215
c) P(X≤20) = 0.000081
therefore would be unusual that fewer that 20 murders were cleared
Answer:
20 is the answer.
Step-by-step explanation:
Substitute 3 in for x and -2 in for y.
4(3) - (-2 to the third power)
12 - -8 = 12 + 8
The answer is 20
