Using the net, we see that the square pyramid breaks down to 4 equivalent triangles and a square. We can use this formula to solve for the surface area:
Sa=A(square)+4*A(triangle)
The formula for the area of a square is
A=l*w
A=7*7
A=49mm²
The formula for the area of a triangle is:
A=1/2b*h
A=1/2*7*12.2
A=42.7mm²
Now that we have the individual areas of the shapes, we can solve for the surface area.
Sa=A(square)+4*A(triangle)
Sa=49mm²+4*42.7mm²
Sa=49mm²+170.8mm²
Sa=219.8mm²
Answer=219.8mm²
ANSWER=A
Answer: Our required probability is 81%.
Step-by-step explanation:
Since we have given that
Probability of defective calculators (C)= 10%
Probability of defective batteries (B) = 14%
Probability of both defective calculators and defective batteries = 5%
So, it becomes.
![P(C\cup B)=P(C)+P(B)-P(B\cap C)\\\\P(C\cup B)=10+14-5\\\\P(C\cup B)=19\%](https://tex.z-dn.net/?f=P%28C%5Ccup%20B%29%3DP%28C%29%2BP%28B%29-P%28B%5Ccap%20C%29%5C%5C%5C%5CP%28C%5Ccup%20B%29%3D10%2B14-5%5C%5C%5C%5CP%28C%5Ccup%20B%29%3D19%5C%25)
So, probability that the calculator has a good case and good batteries is given by
![100\%-19\%=81\%](https://tex.z-dn.net/?f=100%5C%25-19%5C%25%3D81%5C%25)
Hence, our required probability is 81%.
