Answer:
The frequency of oranges is the classroom is 47.37%.
Step-by-step explanation:
The relative frequency of oranges is the number of oranges divided by the total number of fruits.
We have that:
8 students brought 2 apples each. So there are 8*2 = 16 apples
4 students brought an apple and an orange each. So there are 16 + 4*1 = 20 apples and 4*1 = 4 oranges.
7 students brough 2 oranges each. So there are 4 + 2*7 = 18 oranges.
There are 18 oranges, and 20+18 = 38 fruits in total.
So the frequency of oranges in the classrom is
![F = \frac{18}{38} = 0.4737](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7B18%7D%7B38%7D%20%3D%200.4737)
So we know that the word 'product' means multiplication, and that means that h and 4 are being multiplied. Also, one-fifth of x is another way of saying that one-fifth is being multiplied with x. So then we can construct the equation:
![\frac{1}{5} x-(4*h)=35](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20x-%284%2Ah%29%3D35%20)
And we can then simplify this by taking out the multiplication sign:
![\frac{1}{5}x-4h=35](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7Dx-4h%3D35%20%20)
And so since we do not know what x or h is equal to, this is as far as we can go.

Answer:
For part A its A. and for part B its C.
Step-by-step explanation:
From the problem, the vertex = (0, 0) and the focus = (0, 3)
From the attached graphic, the equation can be expressed as:
(x -h)^2 = 4p (y -k)
where (h, k) are the (x, y) values of the vertex (0, 0)
The "p" value is the difference between the "y" value of the focus and the "y" value of the vertex.
p = 3 -0
p = 3
So, we form the equation
(x -0)^2 = 4 * 3 (y -0)
x^2 = 12y
To put this in proper quadratic equation form, we divide both sides by 12
y = x^2 / 12
