Answer: 25%
Step-by-step explanation:
To find percent decrease, you take your final number minus your initial number, over your initial number, so you start with 6-8/8, and get 2/8 or 1/4, then you multiply that by 100, so you get 25. That's your percent decrease.
M=square root of 10 all over 2
Answer:
I think it's D but I am not sure.
coordinates are (x,y)
so for each point, go across the x axis and up the y axis
for the first point, you go over 1 unit and up one unit so the point is
(1,1)
for the second point, you go over 1 unit, but up 4 units so the point is
(1,4)
for the third point, you go over 5 units and up 1 unit so the point is
(5,1)
so your answer is
B) (1,1), (5,1), and (1,4)
Using average makes these scores seem overall low: because it you add them up and divide them by the quantity you get 61.5 as the average which is low for a quiz grade
