the graph represents the money collected at the movie theater on saturday. find the domain when the maximum number of people allowed in the movie theater is 30 people.

graph of y equals 2 times x plus 40 with x axis labeled number of people and y axis labeled amount of money

0 ≤ y ≤ 30
40 ≤ x ≤ 100
0 ≤ x ≤ 30
40 ≤ y ≤ 100

Choose the linear inequality that describes the graph. the gray area represents the shaded region. a: y ≤ –4x – 2 b: y > –4x – 2 c: y ≥ –4x – 2 d: y < 4x – 2

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

Which graph shows the solution to the system of linear inequalities? y-4t< 4 y
