I have a solution here however with a slight change in the equation:

<span> f(x)=3x^2-6x+1

My solution is:

</span>The domain is all real numbers--there are no restrictions like a square root or variable in the denominator 
<span>
this is a U shape parabola and you want to find the bottom point, it is at the vertex </span>
<span>x=-b/2a =- (-6) /2 (3) =1 </span>
<span>f(1) =3(1)^2 -6(1) +1 =3-6+1 =-2 </span>
<span>the minimum is (1, -2) </span>
<span>so the range is all real numbers >= -2
</span>
By examining my solution, you could just answer the problem on your own! I hope it helps!

The histogram shows the prices for six-packs of adult socks and six-packs of kid socks at a store. What is true about the variab
Agata [3.3K]

Answer:

a. There is more variability in the prices of kid socks because they have a greater range.

Step-by-step explanation:

A measure of variability is a summary statistic that represents the amount of dispersion in a dataset. Common examples are range, interquartile range (IQR), variance, and standard deviation.

From the histogram

Highest Number of Packs of Adult Socks = 7

Lowest Number of Packs of Adult Socks = 5

Range = 7 - 5 =2

Highest Number of Packs of Kid Socks = 7

Lowest Number of Packs of Kid Socks = 4

Range = 7-4 = 3

We conclude that there is more variability in the prices of kid socks because they have a greater range.

The correct option is A.
