<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.
Answer: See below
Step-by-step explanation:
In scientific notation, you can tell that it is greater or less than 1 by looking at the exponent. The scientific notation looks like _.__×10⁻. Note: The little lines are blanks for you to fill in. The dot at the bottom is a decimal.
If the exponent on top of 10 is positive, you are moving the decimal to the right side, making the number greater.
If the exponent on top of 10 is negative, you are moving the decimal to the left side, making it smaller and smaller.
By those statements, you can tell if a number is greater or less than 1 by looking at the exponent.
D. there is a perfect association between the variables
