Answer:
In the first two parts you have filled in the table and found the correct graph of the function y = x² - x - 2, which is C.
Now, to solve for part C, you need to consider y = 3 value on the graph C.
Corresponding points on x-axis are the points you are looking for.
<u>The points are: </u>

Answer:
8.5 hrs
Step-by-step explanation:
-A 75th percentile mathematically means that 75% of the time data points are below that value and 25% of the time are above that value.
-We plot the given our data {3 12 2 3 5} to determine the 75th percentile
#We can use to plot our boxplot.
-From the plot, we find our 75th percentile to be 8.5 hrs
Hence, 75% of the time the number of hours spent to prepare was less than 8.5hrs.
