X^2+7x+12/x^2-x-12
x^2+4x+3x+12/x^2+3x-4x-12
x * (x+4) +3(x+4)/ x* (x+3)-4(x+3)
(x+3)(x+4)/(x-4)(x+3)

Answer:

\frac{(x+4)}{(x-4)}

Step-by-step explanation:

Given : \frac{x^2+7x+12}{x^2-x-12}

Solution:

\frac{x^2+7x+12}{x^2-x-12}

Factorize the numerator and denominator.

\frac{x^2+3x+4x+12}{x^2-4x+3x-12}

\frac{x(x+3)+4(x+3)}{x(x-4)+3(x-4)}

\frac{(x+4)(x+3)}{(x-4)(x+3)}

\frac{(x+4)}{(x-4)}

So, \frac{x^2+7x+12}{x^2-x-12} =  \frac{(x+4)}{(x-4)}

Hence Option B is correct.

Suppose that 3 balls will be randomly put into 3 buckets, with each ball being equally likely to be put into each of the buckets
Yuliya22 [10]

Answer:

\frac{1}{27}

Step-by-step explanation:

Since there are a total of three buckets and only one can be chosen at a time, this would mean that the probability of a ball being placed in a bucket is 1/3. Since each ball has the same probability of being placed into any bucket regardless of the where the previous ball landed, it means that each ball has the same 1/3 probability of a bucket. In order to find the probability that all three land in the same bucket, we need to multiply this probability together for each one of the balls like so...

\frac{1}{3} * \frac{1}{3} * \frac{1}{3}  = \frac{1}{27}

Finally, we see that the probability of all three balls landing in the same bucket is \frac{1}{27}

An honest coin is flipped 4 times. Given that the coin landed heads up more than two, what is the probability that it landed hea
arsen [322]

Answer:

probability of getting four head consecutively is 0.2

Step-by-step explanation:

in an experiment coin is flipped 4 times.

given,  coin landed heads up more than two times

outcomes of  coin landed heads up more than two times =

 SAMPLE SPACE :    [ {HHHT}{HHTH}{HTHH}{THHH}{HHHH} ]

chance of getting 4 heads = 1 (HHHH)

Probability = \dfrac{1}{5}

hence the probability of getting four head consecutively is 0.2
