Prove that sin 2x cos 2x=sin 3xx sin of the equation
Answer:
y = 1/6x + 7/3
Step-by-step explanation:
(-2 ,2) and (-8, 1)
Slope=(1-2)/(-8- - 2) = (-1/-6) = 1/6
b = 2 - (1/6)(-2) = 2 - 2/6 = 2 - 1/3 = 7/3
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
