Answer:

1800 square meters.

Step-by-step explanation:

In order to find out the dimensions of the actual parking lot, you must convert the cm to meters. Since 25 is 5x5, we only need to multiply 6 and 12 by 5. From there, we get 6x5=30 and 12x5=60. This means the dimensions are 30 meters by 60 meters. Then, you just need to multiply 30 and 60, from which you get 1800.

Answer: $0.4065$

Step-by-step explanation:

Given : In a sociology class there are 14 sociology majors and 11 non-sociology majors.

Total students = 14+11=25

Number of students are randomly selected = 3

Then, the number of ways to select 3 students from 25 students :-

$^{25}C_3=\dfrac{25!}{(25-3)!3!}=\dfrac{25\times24\times23\times22!}{22!3!}\\\\=2300$

Number of ways to select at least 2 of the 3 students re non-sociology majors :-

$^{14}C_1\times^{11}C_2+^{14}C_0\times ^{11}C_{3}\\\\=(14)\times\dfrac{11!}{2!(11-2)!}+(1)\times\dfrac{11!}{3!(11-3)!}\\\\=(14)(11\times5)+\dfrac{11\times10\times9}{6}\\\\=770+165=935$
