This is the "empirical rule." Approx. 68% of a data set lie within one standard deviation of the mean.
Answer:
An important use of the dot product is to test whether or not two vectors are orthogonal. Two vectors are orthogonal if the angle between them is 90 degrees. ... Thus, two non-zero vectors have dot product zero if and only if they are orthogonal.
Step-by-step explanation:
Time taken by Diana to finish her project is 5 1/3 hours
Gabe took 1 1/4 times as long as Diana, therefore Gabes time will be:
1 1/4 × 5 1/3
=5/4 × 16/3
=20/3
=6 2/3 hours
Paula took 3/4 times as long as Diana, therefore time taken by Paula will be:
3/4 × 16/3
=4 hours
- Hope this helps :)
You would need to get y be itself to make an equation so you would first subtract 1 from both sides--
Py = Qx - 1
Then you would need to divide both sides by P to have y by itself--
y = Qx-1/P
