Where's the histogram?
Answer:
C. The data are skewed to the left, so the median height is greater than the mean height.
Step-by-step explanation:
If this is this is what your questions look like, then the answer is C because the mean is typically less than the median when the data is skewed left.
X^2+7x-18=0
x^2+9x-2x-18=0 ( splitting middle term)
x(X+9)-2(x+9)=0
(x-2) * (X+9) =0
Therefore, X=+2 or -9
Answer:
(-5,6)
Step-by-step explanation:
Answer:
252 cm^2
Step-by-step explanation:
Let x be the length
and
y be the width of rectangle
Then, the area will be:
![A=length*width\\x*y=112](https://tex.z-dn.net/?f=A%3Dlength%2Awidth%5C%5Cx%2Ay%3D112)
If the length and width are changes by a scale factor 1.5.
Then the area will be:
![Area=(1.5x)(1.5y)\\=(2.25)(x*y)](https://tex.z-dn.net/?f=Area%3D%281.5x%29%281.5y%29%5C%5C%3D%282.25%29%28x%2Ay%29)
We already know that xy=112
So the new area will be:
![Area= (2.25)(112)\\=252\ cm^{2}](https://tex.z-dn.net/?f=Area%3D%20%282.25%29%28112%29%5C%5C%3D252%5C%20cm%5E%7B2%7D)
