Answer:
A,C,E
Step-by-step explanation:
A statistical question has variability in the answer, so,
A=could range from any numbers providing a wide range of results
B=it's one answer (eg.5ft4) meaning a range can't be produced
C=could range from any food providing a wide range of results
D=One answer so no variations possible
E= could be a range of numbers
The Answer to this problem is BN=3.8 Units.
<EFD is also shown as e on the diagram. It is 90 degrees. <EFG is made up of the same two lines and is equal to 90 degrees (shown by the little box) so <EFD must be equivalent.
