Question is in the image

The answer is:

Step-by-step explanation:

The equation of a parabola in the intercept form is given by:

Where:

p and q are x-intercepts

Now, we know the parabola intercepts at x=1 and x=3.

So we will have:

Using the point (-1,16) we could find the value of a.

Therefore, the equation is:

The answer is:

I hope it helps you!

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
