Answer:
The student's z-score will not change
Explanation:
Z-scores are used to compare results of an individual or entity to the average population's scores.
Since the adjustment of additional points is added to each class member's score, the adjustment will shift the entire distribution of scores. However, there will not be a change in the relative position of the student's score in the class. As a result, the student's z-score will not change.
<u>Answer:</u>
The correct answer option is: Each x value has one and only one y value.
<u>Step-by-step explanation:</u>
A relationship from a set of inputs to a set of outputs where each input has exactly one corresponding output value is said to be a function.
Here, we are given 
which happens to be a function as no x value is repeated and there is only one corresponding y value to it.
Therefore, option c is the correct answer.
Answer:
-3
Step-by-step explanation:
Step one: Subtract $15 - $5.50 = $9.50
<span>Step two: divide $9.50 ÷ $15 = .633 (rounded) </span>
<span>Step three: Multiply .633 * 100 to change it to a percent. It becomes 63.3% (rounded) </span>
<span>The decrease is 63.33% </span>
<span>Proof: $15 * .63333 = $9.50 </span>
<span>Subtract $15 - $9.50 = $5.50

Answer:
x = 8√3
Step-by-step explanation:
Using the Pythagorean Theorem:
a² + b² = c²
x² + 8² = 16²
x² + 64 = 256
x² = 192
√x² = √192
x = √64 √3
x = 8√3
