Answer:

25% probability

Step-by-step explanation:

If there are three questions with four possible choices, there are twelve total answer choices. if you only get one answer as the correct one in each question then there's three out of the twelve answer choices that are correct in total. Basically, 3/12 = .25 = 25%. that's for total.

Also, with each question having 4 answers with 1 correct, 1/4 = .25 = 25% as well.

I hope this helped!

Answer: 25% is the possibility.

Step-by-step explanation:

So 1 multiple choice will have 4 possible answer.

2 multiple choice will have 4 possible answer.

3 multiple choice will have 4 possible chances.

So it’s out of a 100. You do 100 divided by 4.

Since there are 4 possible answer and it gives us 25%.

To check if our answer is correct then you should do 25 divided by 4 which gives us 100%.

Solve for x by factoring. Check your answers. Can you check to see if I'm correct?
Studentka2010 [4]
If you want to check if your answer is correct, expanding it all out will help!

(x-6)(x+2)=0 <-- Use FOIL tactic 

x²+2x-6x-12=0

x²-4x-12=0 

As you can see, this is identical to the initial equation given. The x values would be 6 and -2, as seen from the factored equation. 

Hope I helped :)

What is the multiple zero and multiplicity of f(x) = x3 + 10x2 + 25x?
elena-s [515]

Answer:

The multiple zero is x=-5.

The multiplicity is 2

Step-by-step explanation:

The given function is

f(x)=x^3+10x^2+25x

To find the zero of this function, we equate it to zero.

\Rightarrow x^3+10x^2+25x=0

We factor to obtain;

x(x^2+10x+25)=0

Observe that; the expression within the parenthesis is a perfect square.

This implies that;

x(x+5)^2=0

This implies that;

Either x=0 or (x+5)^2=0

(x+5)^2=0 has a multiple zero which is

x=-5 and its multplicity is 2.
