The average is 37.
63 * 11 = 693
11/63 is already in its simplest form, because 11 is a prime number and is not an integral factor of 63.
(-9) + (-11-4) + (-11-63) =-9 - 11 - 4 - 11 - 63 = -98
63/11 = 58/11
0.1746
Their product.
It is: 7/11 times 100/1 = 63.'63'% recurring '63'
(Assuming 100 is 100 degrees)cos 100 degrees is equal to - sin 10 degrees.In radians, this is - sin (pi/18).Approximating pi as 22/7, this is - sin (11/63)Using four terms of a Taylor series, this is approximately:- (11/63) + (11/63)^3 /6 - (11/63)^5 / 120 + (11/63)^7 / 5040.- (11/63) + (11^3/63^3) /6 - (11^5/63^5) / 120 + (11^7/63^7) / 5040.Rewriting the fractions with the common denominator 63^7:- (11*63^6/63^7) + (11^3*63^4/63^7) /6 - (11^5*63^2/63^7) / 120 + (11^7/63^7) / 5040.Rewriting again with common denominators of 5040:- 5040*(11*63^6/63^7)/5040 + 840*(11^3*63^4/63^7)/5040 - 42*(11^5*63^2/63^7) / 5040 + (11^7/63^7) / 5040.Now add it all up:[- 5040*11*63^6 + 840*11^3*63^4 - 42*11^5*63^2 + 11^7] / (5040*63^7)Now, some seriously long multiplication gives:(- 3466302962466960 + 17612440516440 - 26846879598 + 19487171) / 19852462421401680Some really easy addition:-3448717349342947 / 19852462421401680And finally, do the long division:-0.17371735939 ... and so on.The actual value is -0.17364817766693034885171662676931So, I got 3 decimal places right. Maybe use a better approximation of pi (like 355/113) and more terms of the Taylor series. But you get the picture.
63*100/11 = 572.7272..
63-52 = 11
the answer of the average of 42, 57, and 63 is 54.
63 11/20 = 63.55
