Take a ruled sheet of paper. Draw (in thick colour) two parallel lines I and m. Draw a transversalt to the lines land m. Label Z1 and 22 as shown [Fig 5.28(i)].
Place a tracing paper over the figure drawn. Trace the lines 1, mandt.
Slide the tracing paper along t, until I coincides with m.
You find that 21 on the traced figure coincides with 22 of the original figure.

Rose drew a regression line for this paired data set. her line passed through (1, 2) and (3, 5) . what is the equation of rose's regression line?

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
