The second choice is not a relation.
The first and third choices have multiple (input, output) pairs that have the same input. Such a relation is not a function. Any time you see this, you know the relation is NOT a function.
The best answer is the 4th choice ...
... {(0, -9), (-9, 0), (-3, -3)}
The normal distribution is also known as the Gaussian distribution. The correct option is D, while the z-score is -2.29.
<h3>What is Normal Distribution?</h3>
The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Since the normal distribution is symmetrical about the mean. Therefore, 0.89 area from the left will be equal to 0.11 area from the right. Therefore, the correct option is D, while the z-score is -2.29.

Answer:
a=2.25
Step-by-step explanation:
Given the equation 4.5=2a, you'd finds the value of "a" and divide both sides by 2.
4.5/2=a
2.25=a
a=2.25
X + 4y = 7 as they both equal the answer. Hope this helps
