Answer:
86 is the mean and the median is 85
Step-by-step explanation:
To calculate the mean all u gotta do is add all the numbers then divide by how many numbers there is and to calculate the median all u gotta do is put them in order 78-95 then mark 1 on each side til you reach the middle and the number in the middle is the answer.
Answer:
undefined
The problem:
Find the slope for the line going through (3,4) and (3,-4).
Step-by-step explanation:
Line up points vertically and subtract.
Then put 2nd difference over 1st.
( 3 , 4)
-(3 , -4)
------------
0 8
So the slope would have been 8/0 but this is undefined.
So the slope is undefined.
Also notice the x's are the same and the y's are difference so this is a vertical line. There is only rise in a vertical line and no run. Recall, slope is rise/run. You cannot divide by 0 so this is why we say the slope is undefined when the x's are always the same no matter the y.
Answer:
[(a + b), c]
Step-by-step explanation:
Midpoint of a segment with extreme ends represented by ordered pairs 
and 
,
Midpoint = 
It is given that extreme ends of the segment QS are Q(2b, 2c) and S(2a, 0)
Coordinates of the midpoint of QS will be,
= 
= [(a + b), c]
Therefore, ordered pair representing the midpoint of QS will be [(a + b), c].
Answer:
$21.25
Step-by-step explanation:
Step one:<em> $100 and you subtract the $15 you spent on a shirt which leaves you with $85.</em>
Step 2: <em>finally you need to divide 4 into 85....Calculate...... You spend $21.25 on each member</em>
