Sometimes it helps to draw it out...

21
therefore, CM + MQ = CQ
17 + MQ = 21
MQ = 21 - 17
MQ = 4 <===
Answer:
Two standard deviations
Step-by-step explanation:
The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;
one standard deviation lie within 68% of the mean
Two standard deviations lie within 95%
Three standard deviations lie within 99.7%
Hence, for the question given, 95% fall within 2 standard deviations of the mean
Answer: 5
Step-by-step explanation:
Let A denotes the number of major defects and B denotes the number of design defect.
By considering the given information, we have

Now, the number of major defects or design defects:

Also,

Hence, the number of design defects were major=5
Discrete data in information that we collect that can be counted and that only has a certain number of value. EXAMPLES OF DISCRETE DATA: include the number of people in a class, test questions answered correctly, and home runs hit.
Hope this helps :)
