Step-by-step explanation:
We know that AXB + CYD and AXB + FZE = 90
20 + CYD = 90 and 20 + FZE = 90
We can see that CYD and FZE are equal so we can use one equation
Let's use 20 + CYD = 90
CYD = 70 and FZE is also equal to 70 because CYD and FZE are equal.
so 70 + 70 = 140 degree
Answer:
a. True
Step-by-step explanation:
This is because, since the sample mean equals the population means, the distribution of the sample means about the sample size would also be the distribution of the sample size distributed about the population mean.
This usually results in a normally distributed population for a sample size greater than 30.
So, if the sample size is greater than 30, the population mean and sample mean would have the same value and distribution.
