If the distance from Haley's house to school is 2.5 cm on the map and the actual distance is 3 miles. What is the scale for the map? I know the answer but I get confused on what I am comparing. Could you explain step by step.

Step-by-step explanation:

so you are trying to find the scale of the map which means you are comparing the distance on the map to the distance in real life. That being said you are trying to find:

For every 1cm on the map how far is that in real life?

so when you make your equation to solve like so (converting the miles to cm for an easy calculation:

2.5x = 48203

in this equation x (your answer) is the scale of map:real life

so x is how far 1cm on the map is in real life

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

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
