What is the value of pi based on the equation for the best-fit line?.
1 answer:
The line of best fit is used to illustrate a linear regression.
The value of pi based on the equation for the best-fit line is 3.0017
<h3>How to determine the value of pi</h3>The equation of the line of best fit is given as:
Where:
- C represents the circumference
- D represents the diameter
The circumference of a circle is calculated as:
Where k represents a constant.
By comparison, we have:
Cancel out D
Hence, the value of pi is 3.0017

Answer:
Seth has 21 nickels
Step-by-step explanation:
Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.
Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then
Solve this equation:
