Answer:
750 of 100,000 chips would be expected to be defective.
Step-by-step explanation:
(3/400) and (?/100,000)
100,000 ÷ 400 = 250.
Multiply 250 by 3 to find the number of defective chips.
250 x 3 = 750.
The early withdrawal fee on this account
250×0.03×(1÷4)=1.875
Why not actually graph |x|=1? You will find that x = 1 and x = -1 are solutions.
Thus, "closed circles on -1 and 1 with no line" is correct.
