Determine the area and the perimeter of the garden
Calculating Area
First, we calculate the 
Where:
So:
Next, we calculate the area of the two semi-circles.
Two semi-circles = One Circle
So:
Where
Area of the garden is
Calculating Perimeter
First, we calculate the perimeter of the rectangle
But in this case, we only consider the length because the widths have been covered by the semicircles
Where:
So:
Next, we calculate the perimeter of the two semi-circles.
Two semi-circles = One Circle
So:
Where
Perimeter of the garden is
To find the answer to this, first, multiply the denominator by the whole number. So 3 times 4.
12+1/4
Next, add together the numerator to the value and put that number as the numerator.
Final Answer: 13/4
True false true cause look it up and you will figure it out
Answer:
The probability is 
.
Step-by-step explanation:
There are 7 democrats and 6 republicans
Number of ways in which 4 democrats and 2 republicans can be selected=![\[{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}\]](https://tex.z-dn.net/?f=%5C%5B%7B%7D%5E%7B7%7D%7B%7BC%7D_%7B4%7D%7D%5Ctimes%20%7B%7D%5E%7B6%7D%7B%7BC%7D_%7B2%7D%7D%5C%5D)
Number of ways in which 5 democrats and 1 republican can be selected= ![\[{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}\]](https://tex.z-dn.net/?f=%5C%5B%7B%7D%5E%7B7%7D%7B%7BC%7D_%7B5%7D%7D%5Ctimes%20%7B%7D%5E%7B6%7D%7B%7BC%7D_%7B1%7D%7D%5C%5D)
Number of ways in which 6 democrats can be selected = ![\[{}^{7}{{C}_{6}}\]](https://tex.z-dn.net/?f=%5C%5B%7B%7D%5E%7B7%7D%7B%7BC%7D_%7B6%7D%7D%5C%5D)
So, favourable outcomes are ![\[{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}\]](https://tex.z-dn.net/?f=%5C%5B%7B%7D%5E%7B7%7D%7B%7BC%7D_%7B4%7D%7D%5Ctimes%20%7B%7D%5E%7B6%7D%7B%7BC%7D_%7B2%7D%7D%2B%7B%7D%5E%7B7%7D%7B%7BC%7D_%7B5%7D%7D%5Ctimes%20%7B%7D%5E%7B6%7D%7B%7BC%7D_%7B1%7D%7D%2B%7B%7D%5E%7B7%7D%7B%7BC%7D_%7B6%7D%7D%5C%5D)
Total possible outcomes =![\[{}^{13}{{C}_{6}}\]](https://tex.z-dn.net/?f=%5C%5B%7B%7D%5E%7B13%7D%7B%7BC%7D_%7B6%7D%7D%5C%5D)
Now, probability=![\[\frac{Favourable}{Possible}=\frac{{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}}{{}^{13}{{C}_{6}}}=0.383\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7BFavourable%7D%7BPossible%7D%3D%5Cfrac%7B%7B%7D%5E%7B7%7D%7B%7BC%7D_%7B4%7D%7D%5Ctimes%20%7B%7D%5E%7B6%7D%7B%7BC%7D_%7B2%7D%7D%2B%7B%7D%5E%7B7%7D%7B%7BC%7D_%7B5%7D%7D%5Ctimes%20%7B%7D%5E%7B6%7D%7B%7BC%7D_%7B1%7D%7D%2B%7B%7D%5E%7B7%7D%7B%7BC%7D_%7B6%7D%7D%7D%7B%7B%7D%5E%7B13%7D%7B%7BC%7D_%7B6%7D%7D%7D%3D0.383%5C%5D)
