those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below
that means, the squared variable is the "x", thus the form is
now, we know the vertex is at 0,1, and two x-intercepts of
thus
solve for "a", to see what that coefficient is, then plug it back in the vertex form equation
I found the table that contains the following data:
25 times:
Column No. 1 2 3 4 5 Total
New York 3 2 2 1 2 10
Connecticut 1 1 1 2 0 5
Pennsylvania 1 1 1 1 1 5
Rhode Island 0 1 1 1 2 5
New York: 10/25 or 2/5
Connecticut: 5/25 or 1/5
Pennsylvania: 5/25 or 1/5
Rhode Island: 5/25 or 1/5
300 times * 2/5 = 120 times for New York
The best estimate of the number of times Amber would pull out a New York quarter is 120.
D, because we already know how much he spent in total so it isnt B, trust me its D
x - 3y =2
2x+ y =11 | *3
x - 3y = 2
6x +3y=33
--------------
7x =35
x=35:7
x=5
x-3y=2
5-3y=2
3y=5-2
3y=3
y=1
Answer:
Count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number. If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
The range is calculated by subtracting the lowest value from the highest value.
