In the week that ended on January 4, there were 24 cases of flu reported in a city's hospital. In the 5 weeks that followed, the number of new cases
reported each week had grown exponentially and can be modeled by this

If the trend continued, would the number of cases reported be greater than
300 after 5 weeks? Explain or show how you know.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
