Variables in algebra are usually represented by letters such as x, y, z, w.
Your expression has only one such letter: y.
Answer:
y =(v-4)^2 -4
Step-by-step explanation:
vertex form of a parabola is
y = a (v-h)^2 +k
where (h,k) is the vertex
y =a(v-4)^2 +(-4)
y =a(v-4)^2 -4
now substitute another point in to determine a
let's pick 0, 12
12 = a((0-4)^2 -4
add 4 to each side
16 = a * (-4)^2
16 = a*16
divide by 16
a = 1
substitute in what we know
y =1 *(v-4)^2 -4
y =(v-4)^2 -4

Option D : 54 is the range of the distribution
Explanation:
The given distribution is 21, 32, 49, 67, 75
The range of the distribution is the difference between the highest value and the lowest value in the distribution.
From the given data, we can see that,
Highest value = 75
Lowest value = 21
The range can be determined by subtracting by the highest value and the lowest value.
Thus, we have,
Range = Highest value - Lowest value
Range = 75 - 21
Range = 54
Thus, the range of the given distribution is 54.
Hence, Option D is the correct answer.
