Answer:
Step-by-step explanation:
Multiply it by the conversion factor to get 350 x 10^-10 meters. You can simplify to 3.5 x 10^-8 meters
The frequency of the second class is 6.
Since the class width is 6 and the lower limit of the first class is 50, this means the first class goes from 50-55. This would put the second class at 56-61. There are 6 data points in this set that would go in the second class.
The answer is -10. I think about negative numbers on a number line with numbers being behind and in front of the zero. To check the answer you can imagine being on -10 and when it says to minus a number you always know that it’s going to go further into the negative. So -10-10 is -20.
I need a picture of the problem or something at least
