1. The answer is d
2. The answer is a
3. The answer is a. The slope of a constant function is always 0.
So to find the medium you need to put the numbers in order from least to greatest so for the first one it would be like this 103, 111, 113, 114, 122, 129,
<span>130, 138, 140, 141, 145 and then you find the number that is in the middle of the set so for sample one it would be 129</span>
Solution:
we are given that
The difference of two numbers is equal to 0.6.
Let the numbers be x and y so we can write

Their quotient is also 0.6.
so we can write

Now solve these two equations together we get





Hence the numbers are -1.5 and -0.9
