You measure cacti growth at two different points. After 20 days the cacti has grown to 20cm, while after 60 days it has grown 30cm. Given this, the growth can be considered exponential. Develop your own exponential model to show the relationship g(t) - growth in cm to time in days. I will mark you as brainliest.

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels. ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis?
