Just add the numbers of the groups 20-34 years and 35-49 years
Our angle teta is:
teta = 3pi/4
since that is larger than pi/2 but less than pi that means that our angle lies in II quadrant (x negative y positive)
sin(3pi/4) = √2/2
cosine and tangent of that angle must be negative because of position of the angle.
cos(3pi/4) = -√2/2
tan(3pi/4) = -1
Answer:
9
Step-by-step explanation:
5x+3x-3= 8x+16-10
5x+3x-8x=16-10+3
8x-8x=9
= 9
Answer:
548 miles
Step-by-step explanation:
O.25m + 210 = 347
0.25m = 347 - 210
0.25m = 137
m = 137/0.25
m = 548
Probabilty = 12×(1/12)^3=1/144
