The ANSWERS and how to get them
1 answer:
Answer: The answers for question 3 are x = 5, y = 13, and z = 10.
Now for question #4. The answer for those are a = 6.40312, b = 6.70820, c = 9.43398, d = 5.29150, e = 4.89898, f = 7.54983.
You would solve all these problems by using this formula a^2 + b^2 = c^2 with a and b representing two of the legs and c representing the hypotenuse (the longest side.) Simply input the respective numbers for the appropriate variables and solve for the missing variable.
Now lastly question #5. We just need to solve for the diagonal length. The answers are as follows. 5.66, 7.07, and 9.9. You get these answers by using the formula for finding a diagonal in a square which is d=2a

The sample mean is
The standard deviation is
Given that the confidence level is then the level of significance is mathematically represented as
=>
Next we obtain the critical value of from the normal distribution table
The value is
Generally the margin of error is mathematically represented as
