Assuming display of computer is at 100%
So increase by 20% = 120 (20/100 *100)
then 20% of 120 is: 20/100 * 120 = 24
So the display is now 120-24 = 96
Hope this helps!
Part a
For horizontal 8*50% = 4 and for vertical 12*75%= 9.
So these values are less than the originals so the new frame is a reduction.
Part b
For horizontal 8*125% = 8*1.25 = 10 and for vertical 12*140% = 12*1.4 =16.8
So these values are greater than the originals sothe new frame is a enlargement.
Simply the standard deviation of the data values is the square root of the variance:

=18
Answer:
D)18
M(p) = -1/m
m(p) = -1/7
y=-1/7x+b
Y intercept
(0,0) or 0
We can substitute this for b giving
Y= -1/7x+0 or Y= -1/7x
I hope this help you
