I am sorry but it is just an example !
Question ) A university has 30,330 students. In a random sample of 270 students, 18 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answer ) 2,022 students will speak three or more languages
Here's why:
Using proportions.
18. x
--- =. ----
270. 30,330
Cross multiply
18 x 30,330 = 545,940
270 multiply x = 270x
545,940 divided by 270 = 2,022
x = 2,022 students
Answer:
the play area is a circle with radius = 12
Step-by-step explanation:
Circle area = A= π r²
r = radius
A = 144 π = 452.39
Diameter = 2r
= 24
circumference = C = 2π r
= 24 π = 75.4
Q2)
Area = π r²
r = 15
r²= 225
area = 706.5
