Answer:
(c) 
Step-by-step explanation:
Given
The attached graph
Required
Find h(3)
The formula to use in solving this is:

Substitute 3 for x

From the attached graph, the value od x = 3 points to the value of y = 1.
So, we have:

260.5 is the median for the data set hope this helps;)
Answer:
Step-by-step explanation:
The easiest and most proper way to approach this task is to combine like terms inside parentheses: (24x + 7 – 12x) => (12x + 7).
Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7). This is an acceptable answer. There is the option of carrying out the multiplication, which results in
3x + 7/4, which is another acceptable answer.
A(b+c)=a•b+a•c
18=18•1
54=18•3
18(1+3)=18•1+18•3
Good luck
-1 - (-7) over 3 - (-1) = M
-1 + 7 over 3 + 1 = M
6 over 4 = M
6/4 = M
3/2 = M
