Answer:
electromagnetic waves
Explanation:
Radiation is the transfer of heat energy through space. Most of them are sent through electromagnetic waves.
To calculate the mean, you add up all of the data values, and then divide that sum by the *number* of values.
For instance, if you wanted to find the mean score at a home run derby, and you’re given the following numbers for home runs scored by each player:
5, 4, 6, 5, 3, 1
You could calculate the mean by adding all of the score up
5 + 4 + 6 + 5 + 3 + 1 = 24
And dividing by the number of hitters (in this case, 6)
24 / 6 = 4
So the *mean score* of the home run derby would be 4.
You can pick it up and move it
