hi, i need to clarify that do i need to know the sample problem on pg 220 for the quiz..thanks
No, this example is for the bonus assignment only and will NOT be covered on the quiz on Tuesday.
The bonus assignment will later be taken up with the class and there will be a related question on your unit test.
Hello Ms, my question is about the bonus assignment, do we check the answers that are on the back of the book, and what if the answers there are wrong????
You can check your answers in the textbook. As it is a bonus assignment, I will not confirm the accuracy of the textbook answers. If you answered the questions correctly and you pay attention to significant digits and units of measurement you are set.
i been trying to enroll in class all day, i tried about 250 times to enter the class code, i get this message:
That class code was found, but no space is available in the class. Please see your teacher about this problem.
what do i do?
I just set up another class with the same gizmo - use the class code LY4FABXUCP. Then use your user name and password as before and it should work. If it doesn't let me know.
thx it works
now it says: You are already enrolled in this class.
