What is the formula for finding residuals? - y-yhat=residual When do you know a residual graph is over predicting? - When the point on the residual graph is below the x-axis, meaning that it's negative. When do you know a residual graph is under predicting? - When the point on the residual graph is above the x-axis, meaning it is a positive number How do you know a relationship between x & y is positive? - If the slope is positive, the graph is positive, so that means it's a positive rel...

NCSSM PLACEMENT TEST WITH COMPLETE SOLUTIONS 100% 2024 latest update Tangent intersects a circle in only 1 place. Secant intersects a circle in 2 places. Intersection of a tangent and a radius form right angles when they intersect. Equation of a circle x minus h squared plus y minus k squared equals radius squared. Circumference of a circle 2 times pi times radius or pi times diameter. Area of a circle pi times radius squared. Central angle is equal to its i...

Accuplacer-Math Terms Define - "ordered pairs" = (x, y) = a single point on a coordinate plane Define - "origin" = (0,0) = the point where two axes meet Explain - "quadrants" = when the two axes (x and y) cross they form 4 quadrants Explain what - "the distance" means Define - "distance formula" for a line(s) = "distance" - the length between two points on a plane - (x1, y1), (x2, y2) * does not have to be forming a line *distance is ALWAYS positive = (Dis...
