Answer:

A. f(x)=(x+6)(x+2)(x-3)

Step-by-step explanation:

The zeros or roots of a function are the numbers that when they are entered into the function the output will be 0.

We will evaluate the given numbers (-6,-2,3)to see in wich option all of them wil give us 0 in the output, Let´s start with the first option A) as follows:

f(-6)=((-6)+6)((-6)+2)((-6)-3)=(0)(-4)(-9)=0

f(-2)=((-2)+6)((-2)+2)((-2)-3)=(4)(0)(-5)=0

f(3)=((3)+6)((3)+2)((3)-3)=(9)(5)(0)=0

As we can see this is the correct option in which all of the values give us the output 0 adn we dont need to evaluate the resto of the options (B), C) and D))

Anastasy [175]

Answer:

P(number greater than 3) = \frac{7}{12}

Step-by-step explanation:

The  Probability of  getting a number greater than 3  means the possibility of getting 4  or 5 or 6

That is

P(number greater than 3) =  P(getting 4)  +  P(getting 5) + P(getting 6)

On substituting the values from the table ,

we get

P(number greater than 3)  = \frac{2}{12} +  \frac{2}{12} + \frac{3}{12}

P(number greater than 3) = \frac{7}{12}

Thus if the number cube is tossed once, P(number greater than 3) is  \frac{7}{12}
