A or D
Step-by-step explanation:
Answer:
Option B. ![20\ ft^{2}](https://tex.z-dn.net/?f=20%5C%20ft%5E%7B2%7D)
Step-by-step explanation:
we know that
The area of a triangle is equal to
![A=\frac{1}{2}bh](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7Dbh)
we have
![b=4\frac{2}{3}\ ft](https://tex.z-dn.net/?f=b%3D4%5Cfrac%7B2%7D%7B3%7D%5C%20ft)
![h=8\frac{4}{7}\ ft](https://tex.z-dn.net/?f=h%3D8%5Cfrac%7B4%7D%7B7%7D%5C%20ft)
Convert mixed numbers to an improper fractions
![b=4\frac{2}{3}\ ft=\frac{4*3+2}{3}=\frac{14}{3}\ ft](https://tex.z-dn.net/?f=b%3D4%5Cfrac%7B2%7D%7B3%7D%5C%20ft%3D%5Cfrac%7B4%2A3%2B2%7D%7B3%7D%3D%5Cfrac%7B14%7D%7B3%7D%5C%20ft)
![h=8\frac{4}{7}\ ft=\frac{8*7+4}{7}=\frac{60}{7}\ ft](https://tex.z-dn.net/?f=h%3D8%5Cfrac%7B4%7D%7B7%7D%5C%20ft%3D%5Cfrac%7B8%2A7%2B4%7D%7B7%7D%3D%5Cfrac%7B60%7D%7B7%7D%5C%20ft)
substitute the values
![A=\frac{1}{2}(\frac{14}{3})(\frac{60}{7})\\ \\A=\frac{14*60}{2*3*7}\\ \\A=\frac{840}{42} \\ \\A=20\ ft^{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%28%5Cfrac%7B14%7D%7B3%7D%29%28%5Cfrac%7B60%7D%7B7%7D%29%5C%5C%20%5C%5CA%3D%5Cfrac%7B14%2A60%7D%7B2%2A3%2A7%7D%5C%5C%20%5C%5CA%3D%5Cfrac%7B840%7D%7B42%7D%20%5C%5C%20%5C%5CA%3D20%5C%20ft%5E%7B2%7D)
Answer:
For any normal distribution, the mean and the median will have the same value. For any normal distribution, the proportion corresponding to scores greater than z = +1.00 is exactly equal to the proportion corresponding to scores less than z = -1.00.
