Answer:
A. 45.28
Step-by-step explanation:
Answer:
z =23
Step-by-step explanation:
The three angles in a triangle add to 180 degrees.
62+95+z = 180
Combine like terms
157 +z = 180
Subtract 157 from each side
157-157 +z = 180-157
z =23
Answer:
B) The sum of the squared residuals
Step-by-step explanation:
Least Square Regression Line is drawn through a bivariate data(Data in two variables) plotted on a graph to explain the relation between the explanatory variable(x) and the response variable(y).
Not all the points will lie on the Least Square Regression Line in all cases. Some points will be above line and some points will be below the line. The vertical distance between the points and the line is known as residual. Since, some points are above the line and some are below, the sum of residuals is always zero for a Least Square Regression Line.
Since, we want to minimize the overall error(residual) so that our line is as close to the points as possible, considering the sum of residuals wont be helpful as it will always be zero. So we square the residuals first and them sum them. This always gives a positive value. The Least Square Regression Line minimizes this sum of residuals and the result is a line of Best Fit for the bivariate data.
Therefore, option B gives the correct answer.
Yes you are correct good job
Answer:
0.16 gallons of paint are used on each piece of furniture.
The answer lies between the whole numbers 0 and 1.
Step-by-step explanation:
we know that
Four gallons of paint are used to paint 20 chairs and 5 small tables.
if each chair and table used the same amount of paint
then
sum the total pieces of furniture
20+5=25 pieces
Find the unit rate
Divide the total gallons of paint used by the total pieces
therefore
0.16 gallons of paint are used on each piece of furniture.
The answer lies between the whole numbers 0 and 1.
