First of all, for median, <em>list the numbers in order.</em>
60, 60, 66, 70
If there are an odd number of numbers, the median is the number in the middle.
If there are an even number of numbers, the median is the average(mean) of the two numbers closest to the middle.
Average of 60 and 66:
60+66 = 126
126/2 = 63
Median: 63

Answer:
1 and 9/20
Step-by-step explanation:
add your fractions together 7/10 + 3/4
make them have the same denom 14/20 + 15/20
so its 29/20
to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.
Suppose <span>A</span><span> is invertible. Therefore the equation </span><span><span>Ax=0</span></span><span> has only one solution, the zero solution. This means that the columns of </span><span>A</span><span> are linearly independent.</span>
You started with $15. 15-15 = 0 and then you earned $30, but spent $12... 30-12= 18
