When finding the mean you should first add up all the numbers which are 12,2,8,6 and 57 which will give you a sum of 85 next you should divide your sum by how many numbers there are which is 5 and your answer should be 17

Answer is 17.


<em>Explanation;</em>


Mean = sum of the value / number of values


To find out the sum of the values you have to add together all given numbers.

Hence,

     sum of the values = 12 + 2 + 8 + 6 + 57

                                    = 85


Number of values means number of data that we have.

According to the given data, there are 5 numbers.


Hence,

    mean = 85 / 5

              = 17

If f(1) = 0, what are all the roots of the function f(x)=x^3+3x^2-x-3? Use the Remainder Theorem.
Sophie [7]
There's no if about it, 

f(x)=x^3+3x^2-x-3&#10;

has a zero f(1)=0 so x-1 is a factor.   That's the special case of the Remainder Theorem; since f(1)=0 we'll get a remainder of zero when we divide f(x) by x-1.

At this point we can just divide or we can try more little numbers in the function.  It doesn't take too long to discover f(-1)=0 too, so  x+1 is a factor too by the remainder theorem.  I can find the third zero as well; but let's say that's out of range for most folks.

So far we have 

x^3+3x^2-x-3 = (x-1)(x+1)(x-r)

where r is the zero we haven't guessed yet.  Again we could divide f(x) by (x-1)(x+1)=x^2-1 but just looking at the constant term we must have

-3 = -1 (1)(-r) = r

so

x^3+3x^2-x-3 = (x-1)(x+1)(x+3)

We check f(-3)=(-3)^3+3(-3)^2 -(-3)-3 = 0 \quad\checkmark

We usually talk about the zeros of a function and the roots of an equation; here we have a function f(x) whose zeros are

x=1, x=-1, x=-3

Can anyone help me? Brainlist if right! Thx :)

Answer:

odd: 4/7

not 3: 6/7

4 or 5:  2/7

spinner spun 2: there both 1/7 i think im

only in 7th grade ;-;

Step-by-step explanation: well there are 7 spaces so the probabilty

of it landing on an odd space on the wheel is how many odd numbers there are over 7 . and there is only 1 three so the chance that it will not land on 3 is 6/7.  there is a 2/7 chance it will land on 4 or 5. and im not to sure abt the last one but like i said im  only in the 7th grade i am taking p classes tho so the rest should be right. :D
