Answer:
39/56
Step-by-step explanation:
When you add fractions, both of the base numbers (denominators) have to be the same number in order to add the top numbers (numerators).
The easiest way to do this is to multiply each denominator by the other number. For example, 8 * 7 and 7 * 8. So you will have 56 and 56. You also need to multiple the numerator by that number. So, 1 * 7 and 4 * 8. So you will have 7 and 32. This will show as 7/56 + 32/56. Finally, add the numerators - > 39/56

Answer:
Mean Deviation = 5
Step-by-step explanation:
The numbers are given as;
8, 12, 12, 25, 10, 14, 4, 3, 22, 10
Mean = Sum of numbers / Population = 120 / 10
Mean = 12
mean deviation involves finding the sum of the absolute values of the differences between the individual elements and the mean. Then divding by the population.
Mean Deviation = |(8 - 12) + (12 - 12) + ( 12 - 12) + (25- 12) + (10- 12) + 14- 12) + (4- 12) + (3 - 12) + (22- 12) + (10- 12)
| / 10
Mean Absolute Deviation = 5
