Apopulation of insects increases according to the law of exponential growth. after 2 days of growth there are 100 insects. after 4 days of growth there are 300 insects. find an exponential growth function that models this data. use the exponential growth model y=ae^it
a. y=33e^-0.05493t
b. y=33e^0.5493t
c. y=66e^-0.5493t
d. y=66e^0.5493t

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.
