The fewest number of students who could have chosen the topic selected by most students is 17.
Since there are six essays and each student is required to write an essay on one of the six topics, the probability of choosing one of the six topic is
P(one topic) = one topic/total number of topics
= 1/6.
Since we have 100 students, the fewest number of students that could choose the topic selected by most students is
n = Probability of selecting one topic × total number of students
= P(one topic) × 100
= 1/6 × 100
= 16.67
≅ 17 students.
So, the fewest number of students who could have chosen the topic selected by most students is 17.

hope it helps tho
Answer: 12.32 is the answer.
Step-by-step explanation: Using the pythagorean thereom we can solve this by using the formula A^2+B^2=C^2.
We substitute in the values,
17^2+B^2=21^2.
Now we simplify.
289+B^2=441
We subtract the 289 from both sides,
B^2=152
Now we use square root to find the answer.
12.32 is the answer.
Hope this helps!
The expression of Volume in cubic meter 
(8)(6)(6)+(8)(6)(4)
The correct option is (1)
<h3>What is Volume?</h3>
Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.
Volume will be,
V= Volume of rectangular pyramid + Volume of cuboid
Volume of rectangular pyramid= * base area* height
= * 6*8*(10-4)
= * 6*8*6
Volume of cuboid= l*b*h
= 4*6*8
So, Volume = * 6*8*6 + 4*6*8
= (8)(6)(6)+(8)(6)(4)
So, The expression of Volume in cubic meter (8)(6)(6)+(8)(6)(4).
