Answer:
Not a function. See below for explanation.
Step-by-step explanation:
In order for a relation to be a function, each input must have one unique output. In this set, we see that points (1,5) and (1,4) have two different outputs with the same input. Therefore, this relation cannot be a function.
Answer:
Step-by-step explanation:
The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. The empirical rule is further illustrated below
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations.
From the information given, the mean is 500 and the standard deviation is 100.
95% of the scores of students would fall within two standard deviations.
2 standard deviations = 2 × 100 = 200
500 - 200 = 300
500 + 200 = 700
Therefore, the probability that a randomly selected student math score is between 300 and 700 is
95%

Answer:
Step-by-step explanation:
radius squared multiplied by pi = area
2 squared = 4
3.14 x 4 = 12.56
Area= 12.56 feet squared
The question is asking you to find the measure of YZ's arc.
The arc of a circle is found by finding the central angle. In this case, that's angle YCZ. Remember that a circle's total degrees is 360. Since the angle that you are trying to find is 16% of the circle, you need to find 16% of 360.
360*0.16 = 57.6
The measure of arc YZ is 57.6 degrees.
