Factor out the following by taking out the GCF18cd^2+12c^2d+9cd
Arturiano [62]

The given polynomial is:

18cd^2+12c^2d+9cd

The first step to factor taking out the GCF is to write each term in prime factored form, so:

\begin{gathered} 18cd^2=2\times3\times3\times c\times d\times d \\ 12c^2d=2\times2\times3\times c\times c\times d \\ 9cd=3\times3\times c\times d \end{gathered}

The second step is to identify the factors common in all terms, they are: 3xcxd

Finally, factor out the GCF:

3cd(6d+4c+3)

The answer is above

Mario draws two cards, one from each of two shuffled decks. Each deck has 12 cards labeled 1-12. What is the
Kay [80]

Answer:

\frac{11}{72}

Step-by-step explanation:

There are two shuffled decks each of which contains 12 cards.

we need to collect two cards, 1 card from each shuffled decks.

Taking the 1st suffled decks we need to drawn one. The probability of getting 6 from the 1st shuffled decks is \frac{1}{12}. In this scenario we need to find the probability of not getting 6 from the 2nd shuffled decks. The probability of not getting 6 is \frac{11}{12}.

The case can also be vice-versa, that is we can get one 6 from the 2nd shuffled decks.

Hence the total probability is 2 times \frac{1}{12} times \frac{11}{12}.

Theoritical probability refers to those outcomes which we suppose to be happen. Experimental probability means the outcomes which can come true if tried.

The given scenario is an example of Experimental probability, as it can also be true if tried.

The population standard deviation of the numbers 3, 8, 12, 17, and 25 is 7.563 correct to 3 decimal places. what happens if each
user100 [1]
Let's figure this out as though we have no idea what the answer would be.

Step One
Find the new five numbers.
3*3, 8*3, 12*3, 17*3, 25*3
9 , 24 , 36, 51, 75

Step 2
Find the average
(9 + 24 + 36 + 51 + 75)/5 = 195/5 = 39

Step 3
Subtract the individual numbers from the average
(39 - 9) = 30
(39 -24) = 15
(39 - 36) = 3
(39 - 51) = - 12
(39 - 75) = -36

Step 4 
Square the results from Step 3
30^2 = 900
15^2 = 225
3^2 = 9
(-12)^2 = 144
(-36)^2 = 1296

Step 5
Take the average of the results from step 4
(900 + 225 + 9 + 144 + 1296)/5
2574 / 5 = 514.8

Step 6
Take the square root of the result from step 5
deviation = sqrt(514.8)
deviation = 22.689

Step seven 
Compare the two standard deviations.
s2/s1 = 22.689 / 7.563 = 3

Conclusion
If you are given 1 set of numbers to find a population standard deviation and you multiply each member by a, then the result will be a * the standard population deviation of the first set of numbers.

Note
Your calculator will do this as well, but you have to know how to enter the data into your calculator. That requires that you follow the directions carefully.
