One study found that one star's worth of improvement on Yelp leads on average to an increase of between 5 and 9 percent in revenue. For a restaurant with revenue of $500,000, how much is a one star improvement worth (in additional revenue) if you use the middle of the range, 7%?

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

the correct answers i think are b. and d.

give me brainliest if it is correct!

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
