Do the area of the triangle and then the square
the answer is 7/6. hope it is right
Answer:
Wen did not take the reciprocal of the divisor.Step-by-step explanation I hope this helps.
Given that sample standard deviation is zero. This indicates that the variance of sample is also zero as square of sample standard deviation is sample Variance. Variance is average of the squared deviations from mean. As shown in below formula
Since Variance = 0 , we substitute in formula and we get the sum of squares of deviations of all data points from mean should be zero. This is only possible if and only if all the data points in the data distribution are same as mean of the data distribution. In the case the variance and standard deviation will be zero.
Variance = Summation n to i = 1
0 = Summation n to i = 1
Summation n to i = 0
