The metric table goes millimeters, centimeters, decimeters, meters, dekameters, hectometers, kilometers. To move up the table, move the decimal point one to the left. If you wanted to change it to centimeters, the answer would be 8,340,000. In kilometers, this is 83.4 kilometers. Hope this helps!
Answer:
(a) The expected score is 12.8
(b) The standard deviation is 3.2 and variance is 10.24
Step-by-step explanation:
Consider the provided information.
You are to take a multiple-choice exam consisting of 64 questions with 5 possible responses to each question.
Here n=64 p=1/5 and q=1-1/5=4/5
Part (a) we need to find the expected score on the exam.
Expected = np
Expected score = number of questions × P(right)

Hence, the expected score is 12.8
Part (b) Compute the variance and standard deviation of x.
Standard Deviation: 
Now calculate the standard deviation as shown:



Variance: 



Hence, the standard deviation is 3.2 and variance is 10.24
