The mean is 12. First, I added all the numbers together. 16+14+15+8+16+3. The sum is 72. Then, I divided the sum by the amount of numbers. 72/6=12. The final answer is 12.
THE LCM OF 3 8 12 15 is 120.
8 and 5/15 - 3 and 8/15 = 4 and 12/15 = 4 and 4/5
8a - 15 = -3 8a = 15 - 3 8a = 12 a = 12/8 = 6/4 = 3/2
4/12 + 3/15 = 4x1/4x3 + 3/15 = 1/3 + 3/15 = 1x5/3x5 + 3/15 = 5/15 + 3/15 = 8/15
The mean is 12. First, I added all the numbers together. 16+14+15+8+16+3. The sum is 72. Then, I divided the sum by the amount of numbers. 72/6=12. The final answer is 12.
THE LCM OF 3 8 12 15 is 120.
8+(-12)+(-3) simplifies to 8-12-3 which simplifies to 8-15 which simplifies to -7.
The mean is the sum of the values divided by the number of values. In this case (12+10+19+8+2+15+1+20+6+11+3+7)/12 = 9.5.
8 and 5/15 - 3 and 8/15 = 4 and 12/15 = 4 and 4/5
5 + -8 = 3 + 12 -3 is not equal to 15
8a - 15 = -3 8a = 15 - 3 8a = 12 a = 12/8 = 6/4 = 3/2
There is only one set of data so there is only one mean. Therefore there is no standard error of the mean.
Mean = 12 Median = 9 Range = 12
4/12 + 3/15 = 4x1/4x3 + 3/15 = 1/3 + 3/15 = 1x5/3x5 + 3/15 = 5/15 + 3/15 = 8/15
Mean = (sum of the samples) divided by (number of samples) = (8 + 12 + 15 + 11) / 4 = 46/4 = 11.5
15/4 x 8/3 = 120/12 = 10
