Answer:
Step-by-step explanation:
Domain is the x values. The interval of x-values that the function encompasses are from 0 inclusive to 7 exclusive. In interval notation that is [0, 7). The range is the y values. The interval of y-values that the function encompasses are from what looks like -2 to 4. In interval notation that is [-2, 4]. The domain goes from the lowest x-value to the highest; the range goes from the lowest y-value to the highest.
A mean is an arithmetic average of a set of observations. The mean number of visits the students made to the library in the last month is 2.32 visits.
<h3>What is Mean?</h3>
A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
For the given frequency table, the sum of the mean and the total number of values can be written as,
Sum = (0×284) + (1×218) + (2×76) + (3×64) + (4×42) + (5×320) = 2330
Total number of values = 284 + 218 + 76 + 64 + 42 + 320 = 1004
The mean for the table can be written as,
Mean = sum/ Total number of values = 2330/1004 = 2.32
Hence, the mean number of visits the students made to the library in the last month is 2.32 visits.
