The probability of drawing a red chip on the first draw is  12/36  =  1/3 .

The probability of drawing a red chip on the second draw is  12/36  =  1/3 .

The probability that both events happen is  (1/3 x 1/3) = 1/9  =  11.1%  .

Answer:

y=3x+19.

Step-by-step explanation:

1) according to the condition the line 't' is parallel to the line 's', it means, the equation of the line 't' is: y=3x+C, where C - unknown number.

2) in order to calculate the 'C', it need to substitute the given coordinates into the equation of the line 't', then:

-2=3*(-7)+C, ⇒ C=19.

3) if C=19 and the equation of the line 't' was y=3x+C, then it is possible to make up the full required equation:

y=3x+19.

What is the factorization??
aivan3 [116]

We first find the zeros of the function , the zeros of the function are those at which points the graph of the function crosses or touches the x axis

here we can see in the graph that graph crosses the x axis at two points , 1 and 7

So the zeros of the function are

x=1 and x=7

It means the factor are

(x-1) and (x-7)

So the factorization is given by

(x-1)(x-7)
