Answer:
Just use photo math
Step-by-step explanation:
The symbol ₁₂P₉ represents the permutations of 9 quantities out of 12.
By definition,
From the calculator,
12! = 479,001,600
3! = 6
Therefore
₁₂P₉ = 479001600/6 = 79,833,600
Answer: 79,833,600
Answer:
9
Step-by-step explanation:
Let larger number be L
and
smaller number be S
The larger is 1 more than twice smaller, so we can write:
L = 1 + 2S
4 times larger is 9 times smaller, so we can write:
4L = 9S
Let's put 1st equation in 2nd and solve for S first:
4L = 9S
4(1 + 2S) = 9S
4 + 8S = 9S
S = 4
Now,
L = 1 + 2S
L = 1 + 2(4)
L = 9
The larger number is, thus, equal to 9
First of all, let's count how many events compose our sample space: since we are rolling two dice, and each of them has six sides, the sample space has 36 possible events, given by all couples , with
Then, we observe that none of the die can give 4 or more, otherwise the sum of the two dice would be at least 5.
So, we have the following possible outcomes:
Red die gives 1, green die gives 3
Both dice give 2
Red die gives 3, green die gives 1.
These are three events out of the 36 possible events, so their probability is
Answer:
The slope is C or 3rd option
(-2/5)
