The range is <span>is greater for data set 2.
- This is because it goes from 21-34 in the first set and 12-36 in the second.

The mean is greater for data set 2.
- This is because the first mean is 27.4 and the second is 28.05. </span>

Answer:

is greater for data set 2 ; is greater for data set 2

Step-by-step explanation:

The range is found by subtracting the highest and lowest value. The range of the first plot would be

34-21 = 13.

The range of the second plot would be

36-12 = 24.

The mean is found by adding together all of the data points and dividing by the number of data points. For the first plot, the sum of the data is 274 and there are 10 data points; this makes the mean 274/10 = 27.4.

For the second plot, the sum of the data is 280.5 and there are 10 data points; this makes the mean 280.5/10 = 28.05.

Answer: 2.12 × $10^{-3}$

The coefficient (in green) will be 2.12

Step-by-step explanation:

Scientific notation is written by multiplying the number by a power of 10. This number is a number between 1 and 10.

Since this is a smaller number, we will be multiplying it by a power of 10 to a negative number.

To get this value to a number between 1 and 10, we must multiply it by 10 3 times (also shown as 10³) which gives us 2.12.

To get back to the original value, we multiply this by $10^{-3}$ . This gives us our answer.

Explain how an estimate helps you place the decimal point when multiplying 3.7 times 5.1

Yuki888 [10]

An estimate helps you place the decimal point because when you place 3.7 and 5.1 to multiply you have to count how many spaces of numbers there are. So the answer is 18.87.
