Answer:
AUB=(1,2,5,6,7,8,12,13,15, 18,20)
AnB={1,2,6,7,8}
Answer:
Step-by-step explanation:
It is a sphere with radius r = 5 cm
volume = (4/3)πr³
= (4/3)π(5³)
≅ 523.60 cm³
Answer:
2
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. Since midpoints will be involved, use multiples of 2 to name the coordinates for B, C, and D.
The lateral surface area is the surface area of the cube excluding the base and the top, which would make 4 square planes.
First we can find the area of a square plane:
4 1/2 x 4 1//2
=20 1/4 ft²
We can then multiply the area of plane by 4:
20 1/4 x 4
=81 ft²
Therefore the answer is 81 ft².
Hope it helps!
The answer would be 24%.
You need to multiply the probabilities of each of those circumstances occurring separately (9/22 for choosing a blue one and 13/22 for choosing a yellow one) in order to find the probability of them happening in a row.
9/22 * 13/22 * 100% ~ 24%
