3. Gaven is paid $12 per hour for mowing lawns and $15 per hour for planting gardens. He can work a maximum of 40 hours per week, and would like to
earn at least $300 this week. If m represents the number of hours mowing
lawns and g represents the number of hours planting gardens, which system
of inequalities could be used to represent the given conditions?
(3) m+g<40
12m + 15g < 300
(1) m+g2 40
12m + 15g 300
(2) m+g2 40
12m + 15g < 300
(4) m + g 40
12m + 15g 300

Which statement about perfect cubes is true

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.

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
