Answer:
Step-by-step explanation:
There isn't one. The first term is x^4.
The other two are stated in terms of k. There is nothing common here.
You can do 2 of the three. Terms 2 and 3 have a common factor of 4k, so what you can get is
x^4 - 4k(k^2 - 1)
Step-by-step explanation:
slope(m)= y2-y1/x2-x1
-2-6/4+2
= -8/6
= -4/3
Answer:
Answer:
Both centres are best described by the median.
Step-by-step explanation:
Here is a summary of the statistics from your data.
City Min Q1 IQR Q3 Max Median Mean σ
Rome 0 3.60 8.65 12.25 16 8.25 7.99 5.20
NY 1 2.25 4.69 6.64 20 5.45 6.39 5.91
The box plots below show that both centres are best described by the median.
The outlier in the New York data greatly distorts the mean but does not affect the median. The mean without the outlier would have been 4.45.
Answer:
The original dimensions of the card were 9 inches length and 9 inches width
Step-by-step explanation:
Let x be the original length and width of the card in inches (remember that it was squared originally). The exercise says that the area of the new width, with dimensions x-4 and x-5 is 20 square inches, therefore
(x-4)*(x-5) = 20
x²-9x+20 = 20
x²-9x = 0
x*(x-9) = 0
x = 0 or x = 9
Since x must be positive, then it cant be 0, thus, x has to be 9. The original dimensions of the card were 9 inches length and 9 inches width.
