EXPLANATION
The given expression is

We complete the square to get the vertex form.
Add and subtract half the square of the coefficient of x.


The vertex is

Answer:
128
Step-by-step explanation:
There are 32 50's in 1600.
So 32x4=128
(4-4x)(x-3)
4x-12-(4x^2)+12x
(-4x^2)+16x-12=(pxq)(x)

<span>The mean of a set of data is 148.87 and its standard deviation is 68.29. Find the z score for a value of 490.19
the z-score is given by:
z=(x-</span>μ<span>)/</span>σ
plugging in the values in the expression we get:
z=(490.19-149.87)/68.29
z=340.32/68.29
z=4.9835
