Now we can multiply 3*2 and 5*1
3*2 =6
5*1=5
Next we add the two numbers
6+5 =11
So this is how we get the answer 11

Putting the values, we get,
The mean temperature of the given data − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3 is 1.9
mean= 1.9
<h3>What is mean of the data?</h3>The mean, or average, is calculated by adding up the data and dividing by total number of data.
Given data: − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3
Now, mean =
mean =
=
mean= 1.9
Hence, the mean of − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3 is 1.9
