The first term of a progression is 5x and the second term is x^2 a. For the case where the progression is arithmetic with a common difference of 14
i. show that x^2 - 5x - 14 = 0
ii. find the possible values of x and the corresponding values of the third term
b. For the case where the progression is geometric with a sum to infinity of 10
i. explain why x cannot be equal to zero
ii. show that 5x/1-x/5 = 10
iii. find the third term

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? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
