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
Answer:
Infinite solutions
Step-by-step explanation:
1) First, you can solve this easily by elimination. Multiply the first equation by -2 in order to cancel out terms when adding to the second equation.
2) Then, add the new set of equations together. However, everything cancels out, bringing us to 0 = 0. This means that the lines the equations make must be the same. Thus, all real numbers must make this equation true, meaning that there are infinite solutions.

Answer:
128
Step-by-step explanation:
160 x .20 = 32
160 - 32 = 128
25 to join and 14 each month
25 + 14m...(m = number of months)
for 6 months...
25 + 14(6) = 25 + 84 = 109
