Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit.
No, the equation is not a good fit because the residuals are all far from zero.
No, the equation is not a good fit because the sum of the residuals is a large number.
Yes, the equation is a good fit because the residuals are not all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.
The equation that produced these predicted values is not a good fit given that the sum of the residuals is a large number.
The sum of the residuals in a regression is a value that is always supposed to be almost equal to zero in a regression analysis.
The residual tells us that the error term has been reduced to the minimum in the regression analysis.

Keep the same compass opening, place the compass point on B, and draw a circle.
Shorten the compass opening, place the compass point on B, and draw two arcs that intersect the circle.
Keep the same compass opening, place the compass at the midpoint of the segment, and draw a circle.
Widen the compass opening, place the compass point on B, and draw a circle.
To construct an equilateral triangle, Ted should maintain the same compass opening and draw another circle from point B. The intersection point of these two circles will form the third point of the equilateral triangle.
To construct an equilateral triangle, the correct next step for Ted, after drawing a circle with compass point on A and reaching B, would be to keep the same compass opening, place the compass point now on point B, and draw another circle. Where this second circle intersects with the first one, that will be the third point of the equilateral triangle.
This is because in an equilateral triangle, all the sides are of the same length. So, keeping the compass opening the same ensures that the distance from A to B is equal to the distance from B to the new point, and hence you get an equilateral triangle.

Step-by-step explanation:
Keep the same compass opening, place the compass point on B, and draw a circle.
you want to buy some shrimp for $100 and you have a coupon for 25% off. This lets the price drop to $75 for your shrimp. You go to the cashier and she says the tax is 5.75. To find the end price you have to multiply .0575 by $75 and then add that to the $75. You get $79.31 as your final price
