It is 639.5. this is how you round numbers to the nearest tenth:
if the digit in the hundredths place is 5 or more you round up one, if it is lower than 5 it stays the same, pay no attention to the thousandths place....ex--> 0.497
the 4 is the tenths place
th 9 is the hundredths place
the 7 is the thousandths place......since 9 is 5 or more you round the 4 up one number, so the 4 would be a 5. pay no attention to the 7. lets do another
0.426
the 4 stays as a 4 because 2 is a lower number than 5.

Answer: Exponents are like the multiplication of a number against itself that many times.
Step-by-step explanation: 2^4=2x2x2x2
3^3=3x3x3
Mean: The average or the center of the value. To find this, you add up all the numbers and divide by how many numbers there are.
Example: 3, 4, 5
3+4+5 = 12.
There are 3 numbers.
12/3 = 4. The mean is 4
Median: Median means the middle value. You place the numbers in order and locate the middle value.
Example: 5, 4, 3 -> 3,/ 4,/ 5. Middle number 4.
Mode: Place the numbers in order then count how much each number appears. The number that appears the most repeatedly would be the mode.
Example: 3, 4, 4, 4, 5, 5.
The mode would be 4.
Range: Locate the highest and the lowest values of the given set and subtract the smallest to the largest.
