Consider the regression ln yi = β0 + β1xi + i . (a) how would you derive the formulas to estimate β0 and β1? [note: no need to derive the formulas] (b) suppose you estimated βˆ 0 = 0, βˆ 1 = 1. suppose the standar error of βˆ 0 is 1 and the standard error of βˆ 1 is 2. how would you go about computing the standard error of the prediction of y at x = 1?

Need 50 will mark brainliest answer. find the lengths of all the sides and the measures of the angles.

Fa bus driver leaves her first stop by 7: 00 a.m., her route will take less than 37 minutes. if she leaves after 7: 00 a.m., she estimates that the same route will take no less than 42 minutes. which inequality represents the time it takes to drive the route, r?

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?
