Answer:
a
Step-by-step explanation:
the total cost is 2.50$/m
option a is the answer you are which class same question is there for me
You want to find the time <em>t</em> such that

Divide both sides by $200 :

Take the logarithm of both sides:

Divide both sides by 0.04 and solve for <em>t</em> :

Answer:

Step-by-step explanation:
<u>Simple Linear Regression
</u>
It a function that represents the relationship between two or more variables in a given data set. It uses the method of the least-squares regression line which minimizes the error between the estimate function and the real data.
Let's compute the best-fit line for the data


First, we find the sums


Then, we compute the averages values


We will also compute the sums of the cross-products and the sum of the squares



We will compute Sxy and Sxx





The slope of the linear regression function is given by

The y-intercept ot the linear function is


Thus the best-fit line is

The correct option is the last one
