EMILIO Andrea says that a system of two linear equations must have at least one solution as long as the lines have different y-intercepts. For example, the equations y = 2x + 4 and y = 4x - 6 have different y-intercepts and have a solution at (5, 14). Select the pair of linear equations that can be used to disprove Andrea's claim. y = - x+4 y=3x-4 @ y-2x = 4 4y-8x = 16 ©y+4x 1 y+ 4x = 3 y =

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
