A protons and electrons is the correct one
Answer: 22
Step-by-step explanation:
Two dozen equals 24, divide it in half leaves 12 vanilla sprinkle doughnuts
the remaining 12 minus the 2 strawberry cream equals 10 chocolate sprinkles
add the 10 chocolate plus 12 vanilla to get 22
Mean - find the sum of that set of numbers then divide your answer by the total of numbers in the set. E.g if the numbers are 10, after finding the sum you divide it by 10 since the numbers are ten.
Median - first arrange the numbers from small to big than find the middle number and if they are two like when the numbers are of an even number than you add the two numbers and divide answer by 2.
Range - arrange the numbers from small to big than minus the smallest one from the biggest number.
