Answer:
27720
Step-by-step explanation:
Given that there are 12 students in a graduate class. The students are to be divided into three groups of 3, 4, and 5 members for a class project.
From 12 students 3 students for group I can be selected in 12C3 ways.
Now from remaining 9, 4 students can be selected for II group in 9C4 ways
The remaining 5 have to be placed in III group.
Hence possible divisions for grouping the 12 students in the class into three groups
= 12C3 *9C4
= 
The answer is :23
B:34
C:56
From the given Venn diagram, the number of students who participate in at least 2 types of sports is
66 + 32 + 74 + 97 = 269
The total number of students is 824.
The percentage that participates in at least 2 type of sports (2 or more) is
100(269/824 = 32.6%
Answer: D. 32.6%
The surface area of the cone is: A. 184π units².
<h3>What is the Surface Area of a Cone?</h3>
Surface area of a cone = πr(l + r), where r is the radius and l is the slant height.
Given the following:
- Slant height (l) = 15 units
- Radius = (r) = 8 units
Surface area of a cone = π8(15 + 8)
Surface area of a cone = 184π units²
