Answer:
The answer is the first one.
Step-by-step explanation:
Okay, so the first one is solved like this:
You do 360*30%. 30% is 0.3 in decimal form. So 360*0.3=108. 108 is the amount that is discounted, NOT the price. You have to do 360-108, which is 252. The discounted price is $252.
Now the second one is solved like this:
You do 360*10% FIRST because the problem says it was marked 10% BEFORE the 20%. 10%=0.1, so 360*0.1=36. You subtract 360-36, which is 324. Then, you multiply 324 by 20% or 0.2, to get 64.8, which is the discount of 20%. You subtract 324-64.8, which is $259.20. So the first one is the answer because it is cheaper since 252 is less than 259.20. If you need this explanation, don't use this word for word. Summarize this in YOUR own words!

Answer:
The median length of all pregnancies will be 266 days.
Step-by-step explanation:
We have been given that the length of human pregnancies varies normally with a mean of 266 days and a standard deviation of 16 days. We are asked to find the median length of all pregnancies.
We know that mean, median and mode all are equal for normal distribution.
Since we are told that the length of human pregnancies varies normally, therefore, the median length of all pregnancies will be same as mean that is 266 days.
