Perimeter = 2*(length + width)
53 m = 2*(2.3 m +w) . . . . an equation to find the width, w
26.5 m = 2.3 m +w . . . . . divide by 2
24.2 m = w . . . . . . . . . . . subtract 2.3 m
The width of the rectangle is 24.2 m
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

To answer this question you first have to find angle acb. You’ll take the sum of the triangle and plug it into an equation. 180=65+(4x+5). You combine like terms and then divide the 4 to both sides to get 27.5. Then you do the same thing to find bcd. 180=27.5+9x-5. Which is 17.1667. I hope that helps!
