Michael and lincoln race home from school each day. lincoln won on monday, tuesday and wednesday, but michael beat him on thursday. what is the experimental probability that michael will beat lincoln home again on friday?

The amount of days they raced is mon, tue, wed and thurs so therefore, four

so our sample size is 4
andlincoln won 3/4 times
andmichael won 1/4 times

so following this process, there is a one in four chance or 25% chance  michael will beal lincoln home

Mechanic A worked for 5 hours and Mechanic B worked for 15 hours

I hope my answer and explanation helped!

okay to get started you need to make a system of equations:

x= number of hours worked by mechanic A

y= number of hours worked by mechanic B

x + y= 20

95x + 60y= 1375

substitute in an equation:

x + y= 20

y= 20- x

95x + 60(20-x)=1375

Solve for x

95x + 1200 - 60x=1375

35x =175

x= 5

plug in x to solve for y

x + y= 20

5 + y= 20

y=15

Check work

then you're done :D
