5/6.
1-2/3=1/3.
(1/3)/2=1/6.
2/3+1/6=5/6.
Answer:
Hence, the probability of exactly 3 successes in 6 trials of a binomial experiment round to the nearest tenth of a percent is:
31.2%
Step-by-step explanation:
The probability of getting exactly k successes in n trials is given by the probability mass function:

Where p denotes the probability of success.
We are given that the probability of success if 50%.
i.e. 
also form the question we have:
k=3 and n=6.
Hence the probability of exactly 3 successes in 6 trials is:




Hence,

In percentage the probability will be:

Answer:
r² + 9r + 6
Step-by-step explanation:
+3| +1 +6 -21 -18
|<u> +3 +27 +18</u>
+1 +9 +6 0
Answer:
=1r² +9r + 6 + 0
=r² +9r + 6 (simplified)
Read on if you want to know how it was done.
To do synthetic division, you first need to get the constant of the divisor and change the sign.
Then list the coefficients of the dividend.
Drop the first coefficient.
Multiply it by the divisor, and write the answer under the next coefficient and add. Repeat till the end.
The answer should be one degree less, the original polynomial.
Answer:
(x,y) = (3, 1/2)
Step-by-step explanation:
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations..
To solve this, add the equations;
x + 2x + 2y - 2y = 4 + 5
3x = 9
x = 3
substitute the value of x into the first equation,
3 + 2y = 4
2y = 4 -3
2y = 1
y = 1/2
