Answer:

To find out the number coming from each school, you need to use the proportion of the school's population out of the population of all three.

Total population = 618 + 378 + 204

= 1,200 students

North Middle school:

= 618/1,200 * 20

= 10 students

Central Middle School:

= 378 / 1,200 * 20

= 6 students

South Middle School:

= 204/1,200 * 20

= 4 students

A total of 100 students are taking a history exam. Each student is required to write an essay on one of six possible topics. Wha
amid [387]

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.

A glass cylinder is completely filled with 24x^5y^8 cubic inches of salt solution. The jug has a base area of 4x^5 square inches
xz_007 [3.2K]
We know that

volume of a cylinder=area of the base*height
area of the base=4x^5  in²
height=<span>24x^5y^8/ 4x^5 in
volume=</span>24x^5y^8 in³

height=24x^5y^8/ 4x^5 ------> (24/4)*(x^5/x^5)*(y^8)------> (6)*(1)*(y^8)-----> 6y^8

the answer is
B: 6y^8
