(40+41+41+45+48+48+49+49+49+40)/10 = 460/10 = 46
mean = 46
This would be 2 because of the rounding rules of it being 5 and up round up and below 5 round down. I hope I helped!
Answer:
s-8
Step-by-step explanation:
ezyyyy
Let a =70° and b= 10° (and a-b=70-10 =60)
We have the following trigonometric identity:
sin(a-b) = sin(a).cos(b)-sin(b).cos(a) OR:
sin(70-10) = sin70.cos10 - sin10.cos70
But sin(70-10) = sin(60) and we know that sin(60°) =(√3)/2
