What is the complete factorization of 108x^2-99y+3

1 answer:

6 0

The quadratic formula would "do" this nicely. a=108; b= -99 and c=3.

Then:
99 plus or minus sqrt(99^2 - 4(108)(3)
x = -----------------------------------------------------
2(108).

Please do the indicated calculations. You should get 2 roots. Now, just supposing that x = 2 were a root (it's not one), then the associated factor would be x-2. Do the same thing with the 2 roots you've just found.

Two dice are tossed. Find the probability of getting the sum of the

pogonyaev

Answer:

Step-by-step explanation:

If you are talking about a die with 6 faces, then 16 isn't possible. 12 is the highest possible number.

If you are talking about some other kind of die, you have to specify it.

I'm going to assume you made a mistake and meant 6.

There are 5 ways to get six

3 - 3

4 - 2

2 - 4

5 - 1

1 - 5

There are 36 ways of throwing 2 dice.

So the probability = 5/36 = 0.1389

If you really did mean 16 then the probability = 0

Anton [14]

Answer:

Mean = 15

Standard deviation = 1.94

Step-by-step explanation:

We are given the following information:

We treat favoring of building a police substation as a success.

P(Success) = 75% = 0.75

Then the number of citizens follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 20

We have to find the mean and the standard deviation.

$\mu = np = 20(0.75 ) = 15\\\sigma = \sqrt{np(1-p)} = \sqrt{20(0.75)(1-0.75)} = 1.94$

Thus, the mean of favoring the substation is 15 and the standard deviation of favoring substation is 1.94
