Jennifer has a map of yellowstone national park. the scale on this map is 1 cm = 9.8 miles. jennifer measured some distances on the map. what is the actual distance from old faithful to canyon? a) 22.54 miles b) 24.5 miles c) 27.44 miles d) 29.4 miles

D) 29.4 miles

Step-by-step explanation:

Given , Jennifer has a map of Yellowstone National Park.

The scale on this map is 1 cm = 9.8 miles.

Jennifer measured some distances on the map.

On map , The distance of Old Faithful to Canyon = 3 cm

Then by applying the scale of map ( 1 cm = 9.8 miles. ) , the actual distance from Old Faithful to Canyon would be :

3 x (9.8 miles )

= 29.4 miles

Therefore , the actual distance from Old Faithful to Canyon would be 29.4 miles.

Hence, the correct answer is D) 29.4 miles.

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
