The range of the following relation R {(3, −2), (1, 2), (−1, −4), (−1, 2)} is Your answer: {−1, 1, 3} {−1, −1, 1, 3} {−4, −2, 2,
nalin [4]
Answer:
The range is all the y values.
Therefore, the range is : {-4,-2,2}.....I realize choice c has all the y values listed, however, if u have repeating y values, u only have to list it once.

Answer:
P (z for -2.23) is -0.9871
Step-by-step explanation:
Given data
mean life x = 753 hours
sample n = 28
mean y = 726
standard deviation SD = 64 hours
to find out
check to have enough evidence to reject his claim
solution
we know that given mean is x ≥ 753
we found mean = 726
so difference = y - x = 726 - 753 = -27
and we know σ = SD/√n = 64 / √28 = 12.094896
Z = y - x / σ
Z = -27 / 12.09
Z = -2.23
so probability value
P (z for -2.23) is -0.9871
so z value is less than alpha = 0.05
so reject
so this is enough evidence to reject his claim

Question:
Felicia makes ½ gallon of fruit punch. She pours an equal amount into 8 glasses.
What fraction of a gallon fruit punch is in each glass?
Answer:
The fraction of a gallon fruit punch is in each glass is 1/16
Step-by-step explanation:
Given
Size of fruit punch = ½ gallon
Number of glass = 8
Required
Fraction of a gallon fruit punch is in each glass?
To solve this question, the following assumption has to be made.
- The 8 glass cups are of equal sizes.
Having said that;
The interpretation of the question is that, the fruit is evenly distributed into the 8 glass cups.
Mathematically, the size of the fruit punch will be divided by the number of glass cups.
So, we have
Fraction = ½ ÷ 8 (convert ÷ to *)
Fraction = ½ * ⅛
Fraction = 1/16
Hence, the fraction of a gallon fruit punch is in each glass is 1/16
