Lucy and her family are going for a hike. the trail they are hiking starts at 32.8 feet below sea level and ends at 35.98 feet above sea level. what is the total distance they hiked?

Distance=68.78 ft

Step-by-step explanation:

With this data, we can find the total vertical distance Lucy and her family hiked, which will be given by the distance above sea level plus, the one below sea level. Both have to be considered, given that the distance is accumulative.

Distance=32.8 feet+35.98 feet=68.78 feet.

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,

here given table is,

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

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
