She is incorrect as 10% of the higher marked up price is larger than 10% of the original price.
For example: If you mark up $100 by 10% you get $110.
If you mark down $110 by 10%, you will get $99, as 10% of $110 ($11) is larger than 10% of $100 ($10).
The results are biased.
When you go to a particular sporting event and ask someone their favorite sport, they are more likely to respond the sport that they're watching at that moment. This creates bias.
Answer:
C) 7
Step-by-step explanation:
3^x−2=2187
Step 1: Add 2 to both sides.
3^x−2+2=2187+2
3^x=2189
Step 2: Solve Exponent.
3^x=2189
log(3x)=log(2189) <<Take log of both sides
x*(log(3))=log(2189)
x= log(2189)/log(3)
x=7.000832
