Let U = {-7, -6, -3, 2, 3, 6, 10, 12, 17, 18}, A = {-7, -3, 3, 10, 17}, B = {-6, 2, 6, 12, 18}, and C = {-7, -6, 2, 3, 12, 17}. Find each set. (Enter your answers using roster notation. Enter {} or ∅ for the empty set.)
(a) (A intersection B) union C =

(b) (A union B union C)c =

(c) (A intersection B intersection C)c

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
