Answer:
b)11
since 11^2 is 11*11 = 12
and when you take the square root of 121
we get 11
(in b- √11^2) , it cancels out the square
square root cancels square since they perform opposite functions
Answer:
-.222
Step-by-step explanation:
-6 x -8= 48 because a negative times a negative is a positive number
Using the binomial distribution, where the number of trials is n and the probability of success is p, the mean is equal to np.
Therefore the mean of x in the question is 100 * 0.7 = 70.
The answer is: 70 circuit boards.
Answer:
R - chart
Step-by-step explanation:
Range chart (R chart) is a control chart used for processes with two or more subgroups to determine if a process is stable or not. It monitors the mean and range of a normally distributed variable simultaneously collected at regular intervals during a given time. It is used when measuring small subgroups between two and ten at regular intervals from a process. Iy is a;so used for constant subgroups.
