The lowest score you can earn on the next test and still achieve an average of at least an 88 is 107
<h3>Mean of data</h3>
Mean is the average of numbers.
Mean = sum of data/sample size
Let the lowest score be "x" such that;
Mean = 74+78+90+91+x/5
88 = 74+78+90+91+x/5
88(5) = 74+78+90+91+x
440 = 74+78+90+91+x
440 = 333 + x
x = 440 - 333
x = 107
Hence the lowest score you can earn on the next test and still achieve an average of at least an 88 is 107

Answer:
The range of the graph is:
-∞ < y < 2
Hence, option C is correct.
Step-by-step explanation:
We also know that range is the set of values of the dependent variable for which a function is defined.
In other words,
Range refers to all the possible sets of output values on the y-axis.
From the given graph, we can easily observe the vertical extent of the graph is all range values between -∞ and 2.
In other words,
The range of the function lies in the interval: (
-∞, 2)
Therefore, the range of the graph is:
-∞ < y < 2
Hence, option C is correct.
