Find the mean of the data.
{ 4, 5, 7, 10}
Round to the nearest tenth
A)6.5
B)6
C)5.3
D)6
Add the four numbers and divide by 4. What answer do you get?
6.5 ... thanks :)
Right! And you're welcome.
To find the mean of a set of data, you need to calculate the sum of all the values in the data set and then divide by the total number of values.
In this case, the given data set is {4, 5, 7, 10}.
Step 1: Add up all the values in the data set:
4 + 5 + 7 + 10 = 26
Step 2: Calculate the mean by dividing the sum by the total number of values:
26 / 4 = 6.5
To round to the nearest tenth, we look at the digit in the hundredth place (the digit after the decimal point). If the digit is 5 or greater, we round up; if it is less than 5, we round down.
In this case, the digit in the hundredth place is 5, so we round up.
Therefore, the mean of the given data set, rounded to the nearest tenth, is option A) 6.5.
