Agiven binomial distribution has 10 trials and probability of success p=1/3. compute the standard deviation and explain your solution

1.49

Step-by-step explanation:

We know that the standard deviation in a binomial distribution is given by :-

, where n is the number of trials and p is the probability of success.

Given : The number of trials :

The probability of success =

Then , the standard deviation will be :-

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
