Rickey is planning to take some friends on a rafting trip for his birthday for each trip the rafting company charges are based on the number of people rafting n and the number of miles rafted during the trip t the total charge for a trip will be 35 per person plus 5 per mile of rafting if Rickey has a budget of 300 for the trip which of the following combinations of number of people and number of miles would result in a total charge that is less than or equal to his budget

47 - 90 = 43

43 - 180 = x

x = 137

[tex]Set up the problem using the given picture.[/tex]

answer: 33 ( approx)

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, [tex]a = \frac{\sum y \sum x^2 - \sum x\sum xy}{n\sum x^2 - (\sum x)^2}[/tex]

here given table is,

price ($), x : 18 23 25 29 30 33

pairs sold, y : 16 13 10 8 6 2

so, [tex]\sum x = 158[/tex] , [tex]\sum y = 55[/tex], [tex]\sum xy = 1315[/tex],

[tex]\sum x^2 = 4308[/tex] and [tex]\sum y^2 = 629[/tex],

thus, slop of the given line is,

[tex]a = \frac{55\times 4308-158\times 1315}{6\times 4308-(158)^2}[/tex]

⇒ [tex]a = \frac{29170}{884}[/tex]

⇒ [tex]a =32.9977375566[/tex]≈ 33
