Answer: The answer is C
Step-by-step explanation:
Step-by-step explanation:
1) the length of the side is:
![\frac{4-\sqrt{2} }{\sqrt{2}}=2\sqrt{2}-1.](https://tex.z-dn.net/?f=%5Cfrac%7B4-%5Csqrt%7B2%7D%20%7D%7B%5Csqrt%7B2%7D%7D%3D2%5Csqrt%7B2%7D-1.)
2) the required perimeter is:
![P=4(2\sqrt{2} -1)=8\sqrt{2} -4.](https://tex.z-dn.net/?f=P%3D4%282%5Csqrt%7B2%7D%20-1%29%3D8%5Csqrt%7B2%7D%20-4.)
3) the required area is:
![A=(2\sqrt{2} -1)^2=9-4\sqrt{2}.](https://tex.z-dn.net/?f=A%3D%282%5Csqrt%7B2%7D%20-1%29%5E2%3D9-4%5Csqrt%7B2%7D.)
Answer:
B. 4
Step-by-step explanation:
4 is the best answer for your question
Add all the chips to find the total amount.
7 + 9 + 3 + 6 = 25 chips
Since there are 6 blue chips (6/25), that's the probability of just getting once.
When you pick a blue chip and it doesn't get replaced, then that means there is one fewer blue chip and one fewer from the total amount.
5/24
Multiply both probabilities.
6/25 * 5/24 = 30/600
Simplify.
30/600 → 1/20
Therefore, the answer is B
Best of Luck!
