The range of the dataset = 47
What is the range of a dataset?
The range of a set of data is the difference between the greatest number and least number
The given data set is:
{14, 25, 61, 18, 30, 32, 28, 45, 21}
The greatest number = 61
The least number = 14
The range of the dataset = Greatest Number - Least Number
The range of the dataset = 61  -  14
The range of the dataset = 47

Answer:
<u>The equation is:</u>
<u>We have two points:</u>
A)
<u>Find the slope using these two points:</u>
- m = (99 - 68)/(620 - 310) = 31/310 = 0.1
<u>Use one of the points to find the y-intercept b:</u>
- 68 = 0.1*310 + b
- 68 = 31 + b
- b = 68 - 31
- b = 37
<u>The equation is:</u>
B)
<u>Find the value of y when x = 980:</u>
- y = 0.1*980 + 37
- y = 98 + 37
- y = 135
The total cost is $135

Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of the circle into center radius form is equal to

where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have


so
the center is the point 
the radius is 
therefore
the graph in the attached figure
