Answer:
1 1/5
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
Step-by-step explanation:
Two angles are coterminal if they differentiate in a factor of k*(2pi). This is a multiple of 360 degrees.
In this case 21 [pi /10] = [pi / 10] + 20 [pi/10] = [pi/10] + 2pi, then 21pi/10 is coterminal with pi/10.
In the case of -pi/10 you cannot get to pi/10 by adding a multiple of 2pi , then they are not coternminals.
Conclusion: you would not be right.
Two conditions under which we can assume that the sample means follow a normal distribution are as follows:
1). If the sample size is large enough, n greater than or equals 30, the sampling distribution is approximately normal regardless of the shape of the population.
2). In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean.
