Step-by-step explanation:
frist ordering the data
4,4,4,5,6,7,7,7,10,11 then
3. the most common ages are 4& 7
4. the range = high - low so 11 - 4 =7
5.the median is Nth/2 + Nth/2 +1 then
10th/2 +10th/2 +1
(5th +6th)/2 = median
(6 +7)/2 =13/2 = 6.5 is the median of children
D) 61 degrees
the two angles not touching the exterior angle add up to be the exterior angle therefore you plug in each of the answers by adding them to 57 until you get 118
57+61=118
