Hey there! I'm happy to help!

A variable is a letter or symbol used to represent an unknown number.

HELP ASAPPPP
Nookie1986 [14]

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

A distribution has the five-number summary shown below. What is the range
Nady [450]

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.
