Answer:
The equation for total cost function is
C(x)=100+270x
Step-by-step explanation:
Variable cost per per board =total cost per day-fixed cost per day/daily output
total cost per day is $5,500
fixed cost per day is $100
20 boards are produced per day
variable cost per board=($5,500-$100)/20=$270 per day
Total cost C(x)=fixed cost per day+ variable per board*number of daily output
Since daily output is represented also by x ,total cost function is given thus:
C(x)=100+270x

The measure in linear-regression analysis that provides the percent of variation in the dependent variable as explained by the regression equation is the Coefficient of Determination.
<h3>What is the Coefficient of Determination?</h3>
This is a measure that allows us to see just how much the variation in the dependent variable, is as a result of the independent variable and is therefore explained by the regression equation.
The Coefficient of Variation is very important because it helps to show the usefulness and accuracy of the regression equation model.

Answer:
Every decade, the number of species decays by a factor of 0.0834.
Step-by-step explanation:
Let be 
, 
. The decay rate per decay is deducted from the following relation:
