To determine the best estimate for the number of COVID-19 cases in the UK on day 22 using the graph, locate day 22 on the x-axis and find the corresponding value on the y-axis.
Since I cannot view the image directly, I cannot provide an exact answer. However, you should look carefully at the graph around day 22.
If you see that the y-axis value for day 22 is around 30,000, then that would be the right choice. If it appears closer to 25,000, then that’s your answer. Similarly, check for values near 21,000 and 3,500.
Please select the answer that aligns with the number corresponding to day 22 on the graph.
