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
Let, the numbers = x,y
x/y = 3/5
total ratio units = 3+5 = 8
value of 1 unit = 135/8 = 16.875
So, numbers would be 3(16.875) & 5(16.875) = 50.625 & 84.375
so, your answer is 50.625 & 84.375
Ratio and propoertion
6 to 4=x to 6
6:4=x:6
6/4=x/6
3/2=x/6
mutiply both sides by 6
18/2=x
9=x
answer is 9 cups of water
Answer:
0.000001
Step-by-step explanation:
It is because 10 is represented as just like 10 and then in a certain place. And then the negative means it is to the right of the decimal. 6th power means the 6th place. So, basically it means, 10 in the 6th to the right place which is 0.0000010. You do not need the last zero because there is no value after that, so 0.000001.
