Answer:
10y³
Step-by-step explanation:
y appears 3 times.
Which means y is multiplied by itself 3 times.
Then, simplify 5 x 2, which is 10, then put y3 after 10.
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
Simplify:
The equation is already simplified =====> (6x² - x - 1)/(x - 1)
Solve:
Solution (6x² - x - 1)/(x - 1) =======> 6x + 5 + 4/x - 1
Steps:
Apply Long Division on:
(6x² - x - 1)/(x - 1)
Divide:
(6x² - x - 1)/(x - 1):
(6x² - x - 1)/(x - 1) = 6x + 5x - 1/x - 1
= 6x + 5x - 1/x - 1
Divide:
5x - 1/x - 1
5x - 1/x - 1
= 5 + 4/x - 1
Answer ======> 6x + 5 + 4/x - 1
Hope that helps!!!!! : )
The solution is 1/4 because 25/100 / 25/25 1/4
