Answer:
The mean number of the children is 1.2
<em></em>
Step-by-step explanation:
Given
Children: 0, 1, 2, 1, 2
Required
Determine the Mean number
The mean of a set is calculated as follows;
Where x is the given set and n is the number of sets
In this case, n = 5 children
Hence;
<em>Hence, the mean number of the children is 1.2</em>
If the 2q is raised to the second power the answer is 2q^2+7q+3
The factor of 11 is going to be 77 because you have to stay in between 70 to 80
and 7 times 11 is 77. It also has to be a number in the 11 timetables. It can't be 88 because we can't cross 80 so the factor is going to be 77.
Hope it helps
