Answer:
1. You cannot divide by zero.
2. The inequality is equivalent to -20.2 > 0, which is false.
<span>The answer is She should have multiplied by 2 instead of dividing by 2.

The first step to do is to calculate first the total
household waste generate for the two years. That is:
total waste generated = 23,400,000 tons + 48,100,000 tons
total waste generated = 71,500,000 tons
Now, to write either a very big number or a very small number
in a form of scientific notation simply means to write it in a decimal form
such as: 12.5 * 10^10
Now to write 71,500,000 in scientific notation, the decimal
form is 7.15, however we still need to find out the * 10^n factor. The value of
n depends on the number of places the decimal point was moved. If the movement
was from right to left, the value of n is positive and if the movement was from
right to left, the value of n is negative. Since the decimal point was moved by
7 places, hence the complete scientific notation is:
7.15 * 10^7 tons
Answer:
1) The mean is actually 31
2) True, the mean would be about 35.
3) True, the mean would change because more medals were added for the USA.
4) True, the mean would be effected because two is added. It results in a increase
