Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
E let A=all of the cars that had an automatic transmission.. B=all of the cars that had anti-lock brakes SI just tells us that B is a part of A...not suffi SII tells us AUB, which is set A itself is 23..not suffi combining two... still not sufficient as we require A-B
An NoA T ......... ___________ Auto |___|___|___| Man |___|___|___| T........|___|___|___|
-I hope that came out. If not: You need to make a box with 9 square so there are 3 rows, 3 columns. Label the columns as Antilock, No Antilock, and Total... and the rows at Automatic, Manual, and Total.
-In the bottom right cube, fill in the total of 25 cars. This was given to you. Then, plug in numbers, and sum columns and rows. Here is how mine came out for this problem while looking to see if both statements together can work.
