It is a sequence of 5 numbers.
The numbers could be the start of the sequence generated by the polynomial:
Un = (59n4 - 562n3 + 1657n2 - 1442n + 360)/24 for n = 1, 2, 3, ...
can 3+23+ 23+10+50=1150
17/5 x 19/10 = 323/50 or 6 and 23/50
15 and 50 / by 5 = 3 and 10 3/10
2.3 = 23/10 and reduces to: 2 3/10
To find the sample mean, add all the numbers together and then divide by the total count of numbers. For the given set (23, 8, 3, 6, 10), the sum is 50. There are 5 numbers, so the sample mean is 50 divided by 5, which equals 10.
-23/7 x 7/50 = -23/50
2 3/10 or 23/10
The decimal 0.0031 as a fraction would be 31/10000.
23 / 10 is equal to 2.3 or 2 3/10
0.3x - 0.2y = 4 (or you can multiply by 10 in order to work with whole numbers) 0.2x - 0.3y = 5/23 3x - 2y = 40 2x -3y = 50/23 2(3x) - 2(2y)= 2(40) -3(2x) - (-3)(3y) = (-3)(50/23) 6x - 4y = 80 -6x +9y = -150/23 6x - 6x - 4y + 9y = 80 - 150/23 5y = 1690/23 y = (1690/23)/(5) y = (1690/23)(1/5) y = 338/23 2x - 3y = 50/23 2(338/23) - 3y = 50/23 676/23 -3y = 50/23 -3y = -676/23 + 60/23 -3y = -616/23 y = (-616/23)/(-3) y = (-616/23)(-1/3) y = 616/69
10/3 * 5 = 5*10/3 = 50/3 50/3 is 16+2/3 and about 16.67
23 + 3 + 17 + 7 = 50
