Answer:
12.5% bought a hard copy. 42.5% printed it from the web. And 45% read it online.
Step-by-step explanation: Since there are 200 students in total, think of 200 as 100% of students. You would divide 25/200 which equals 0.125 then multiply 0.125 times 100 which is 12.5 or 12.5%. Same process with the other numbers (85/200)x100=42.5 (90/200)x100=45. Hope this is what the question was asking
Answer:
Solve the numbers in the brackets first
9+3 = 12
12/2 = 6
14-5 = 9
9 × 3 = 27
Take the answers got from the two brackets and multiply them together
6×27 = 162
C is at the bottom end so make C there and then you’ll have ABC
Theres a line with origin at (0,0) and ends in (3,-2)
because its known y and x apply
tan ∆= y/x
tan∆ = -2/3 = -0.6666
then ∆ = -33.68 degrees
Angle = 360° - 33.68 = 326.32 degrees
then tan 326.32= -.6666
cotan x = 1/ tanx= -1.5
sin 326.32 = -.554
Cosecx 1/sinx = -1.8050
cos 326.32= 0.8321
secx = 1/cosx= 1.2017
You can use the Ruffini's rule. The answer using this method is,
And you can see that the multiplicity of the zero x=-4 is 2, and the multiplicity of the zero x=+3 is 1.
