Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. if the decimal is being moved to the left, the exponent will be positive. all i really did was subtract the numbers without the exponents. but this is useless right now so the answer is: 2.1*10^7
Basically: 2.1 times 10 to the power of 7
Answer:
What are we supposed to simplify? 8/81?
Step-by-step explanation:
First we need to find the common denominator for 8 and 12.
8 = 8, 16, 24
12 = 12, 24
So we have 24 as our common denominator.
5 3/8 = 5 9/24
<u>2 3/12 = 3 6/24</u> now we can add.
8 15/24
So that would be your answer 8 15/24
Hope this helps you. :-)
I believe the answer is 40000
Answer:
(I don't know how to do part B sorry :(. But I can help you with part A)
Part A: The mean of the data is 5
Step-by-step explanation:
To find the mean, you add up all the numbers, then divide the numbers depending on how many numbers there are. In this case:
4 + 3 + 4 + 5 + 6 + 6 + 8 + 4 = 40
------------------------------------------------------------------------------------------------------------
Next we divide:
40 ÷ 8 = 5

Have a good day :)
