step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where, $$a = \frac{\sum y \sum x^2 - \sum x\sum xy}{n\sum x^2 - (\sum x)^2}$$

here given table is,

price ($), x : 18 23 25 29 30 33 pairs sold, y : 16 13 10 8 6 2 so, $$\sum x = 158$$ , $$\sum y = 55$$, $$\sum xy = 1315$$, $$\sum x^2 = 4308$$ and $$\sum y^2 = 629$$, thus, slop of the given line is, $$a = \frac{55\times 4308-158\times 1315}{6\times 4308-(158)^2}$$ ⇒ $$a = \frac{29170}{884}$$ ⇒ $$a =32.9977375566$$≈ 33 answered: Mrdwarf7163 28.06.2019 14:30 answer step-by-step explanation: answered: darriennichole 27.06.2019 22:40 b and c step-by-step explanation: answered: einsigcn8481 25.06.2019 11:30 the answer is a i belaeve atleast thats what my calculator just gfave me step-by-step explanation: ### Other questions on the subject: Mathematics Data are collected to see how many ice-cream cones are sold at a ballpark in a week. day 1 is sunday and day 7 is the following saturday. use the data from the table to create a sc...
