Step-by-step explanation:
Answer:
<u>The z-score = -3.7 and p (-3.7) = 0.00011 or 0.011%</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Mean of time to finish a test = 60 minutes
Standard deviation of time to finish a test = 10 minutes
Time that a student finishes the test = 23 minutes
2. What is the z-score for the student?
z-score = (Time that a student finishes the test - Mean of time to finish a test)/Standard deviation of time to finish a test
Replacing with the real values:
z-score = (23 -60)/10 = -37/10 = -3.7
<u>z-score = -3.7 and p (-3.7) = 0.00011 or 0.011%</u>
Answer:
E) Ray DC
Step-by-step explanation:
The bisecting line is Ray DC because comparing your answer, Ray CB is still part of the original line AB. The Bisecting line would be a ray that intersects on the original line AB. Which in this case would be Ray DC.
Answer:
$17.85 for the 21 fancy cupcakes
Step-by-step explanation:
The greatest common factor in this expression is 3x^4. Let's take it out:
3x^4(u^4 - 1)
u^4 - 1 is a difference of two squares and can be factored further:
3x^4(u^2 + 1)(u^2 - 1)
u^2 - 1 is also a difference of two squares:
3x^4(u^2 + 1)(u + 1)(u - 1)
