Answer:
It should be (-1,5). Are you sure the answers are written correctly? The third one is correct but the 1 in it needs to be a negative
Answer:
It increases the mean value of the prizes
Step-by-step explanation:
If you order the numbers from the lowest to the highest, the median is the number placed in the middle of the ordered list. In this case, there are values repeated many times (there are 100 values, $1 is repeated 44 times and $5 is repeated 25 times, so $5 is the mean), then the presence of a high value with only one presence doesn't modify this median.
On the other hand, the mean is always affected but all data set, given that $100 is the highest value, the mean will increase.
Equation of a line is:
y=mx+C
------------------------
We're looking for m as m stands for gradient.
2x-6y=0 (Divide all terms by 2)
x-3y=0
3y=x
y=1/3x
y=1/3x+0
Therefore m=1/3, C=0.
Example A means
For every #of felt pieces you multiply that by the cost of one piece of felt to see how much you spent
Example
Felts cost $3 a piece
You get 7 pieces
7 x 3= 21
You spent $21 on felt
