Answer:
Choice B
Step-by-step explanation:
We can perform a least squares regression model in Ms. Excel to determine the equation of the line of best fit for the data given;
The first step is to enter the data into any two adjacent columns of an excel workbook. Next, click on the Data ribbon followed by the Data Analysis tool pack. We then proceed to select regression from the pop-up window. The final step is to select the y range and the x range of values from our data.
Once we click ok, Excel returns our least squares regression model as shown in the attachment below.
The coefficient of X variable 1 is our slope.
Answer:
I'm putting C but I'm not sure ill let you know if its right after the test
Step-by-step explanation:
We know that
if <span>4 electricians can complete a job in 8 hours
then
</span>100% of a job -------> 8 hours
x------------------> 1 hour
x=100/8----> x=12.5%
divide by 4 electricians
12.5%/4-----> 3.125%
that means each electrician can complete 3.125% of a job in 1 hour
therefore
3 electricians-----> 3*3.125%----> 9.375% in 1 hour
so
9.375%-----------> 1 hour
100%--------------> x
x=100/9.375----> x=10.67 hours
the answer is
10.67 hours
I would say it is considered a binomial
14/16
Then reduced it would be
7/8 you leave 16 and add 11 to 3 and get that number
