Can you help me to create a histogram graph with the following data please?
AlekseyPX

The attached graph represents a histogram that has a range of 55

<h3>How to create the histogram?</h3>

The range is given as:

Range = 55

The range is calculated as:

Range = Maximum - Minimum

So, we have:

Maximum - Minimum = 55

Rewrite as:

Maximum = Minimum + 55

Let the minimum be 10.

So, we have:

Maximum = 10 + 55

Evaluate

Maximum = 65

The following dataset can be used to create the histogram

Score   Frequency

10           2

15            5

45          3

65         1

This is so because it has a range of 55

See attachment for the histogram

Step-by-step explanation:

The equation of a circle of radius r, with center is (a,b) is

(x-a)^2+(y-b)^2=r^2.

x^2+(y+1)^2=4^2=(x-0)^2+(y-(-1))^2=4^2 so that a=0, b--1 and r=4.
