Answer:
2 students
Step-by-step explanation:
32 students are divided into fourths:
32/4 = 8
Each group has 8 people.
1/4 of the students in each group is the same as dividing 8 into fourths:
8/4 = 2
2 students from each group will go up to the front of the classroom.

Answer:
51%.
Step-by-step explanation:
If we have that the probability when at least one wins is 0.3, it means that the probability that none wins would be:
1 - 0.3 = 0.7 would be the probability of not winning any of the first two games, how are two games and are independent events, the probability of not winning any of the 4 games would be:
(0.7) * (0.7) = 0.49
Therefore, the probability of winning at least one game, would be the complement of not winning any, that is:
1 - 0.49 = 0.51
Which means that the probability of winning at least 1 of the four game is 51%.
Answer:
256 sq cm
Step-by-step explanation:
cube is a three-dimensional figure with six congruent square faces. Since each face is congruent, each of the edges have the same length.
The cross-section described is shown below.
The cross-section is also a square which is congruent to the other faces of the cubes. Therefore, the edges of the cross-section will each measure 16 cm. Find the area by using the formula for the area.
A=lw
=(16cm) (16cm)
=256 sq cm
So, the area of the cross-section is 256 sq cm.
