Answer:
Step-by-step explanation:
In constructing a confidence interval about the mean, the central limit theorem is usually applied. This makes it possible to use the normal distribution. As the number of samples is increasing, the distribution tends to be normal. This would require using the z distribution. In the case where the sample size is small, we assume a normal distribution and use the t distribution. Therefore, the given statement is true.
Answer:
The angle that is supplementary to angle ∠ Z2 is 136°
Step-by-step explanation:
Given as :
∠ Z2 = 44
Let The supplementary to ∠ Z2 = ∠x
∵ For Supplementary angle , measure of Two angles = 180°
Or, ∠x + ∠ Z2 = 180°
Or, ∠x + 44° = 180°
Or, ∠x = 180° - 44°
So, ∠x = 136°
Hence The angle that is supplementary to angle ∠ Z2 is 136° Answer
The answer for 10x - 2y = 20 is y= 5x - 10
The answer for 5x = y + 10 is y = 5x - 10
so basically from this 5x - 10 is the results and 10x - 2y = 20 and 5x = y + 10 are different problems that lead to the same result, hope this helps
