Answer:
The relation is 'a function that is one-to-many'.
Step-by-step explanation:
From the table, we can see that element 10 i.e. y=10 in the range, corresponds to two elements i.e. x=-5, and x=5 in the domain.
In other words, the given table represents the many-to-one function as an element of the range y = 10 corresponds to more than one element in the domain.
Therefore, the relation is 'a function that is one-to-many'.
Answer:
a) Total cost = 49 + 38.75m
b) Total cost = 149 + 38.75m
c) The graphs of the lines are parallel and both has slope of - 2.5
d)Difference in total cost = $132.5
Step-by-step explanation:
Total cost , TC = Initial membership fee + monthly charges
a) TC = 49 + 38.75m
b)TC = 149 + 38.75m
d) 149 + 38.75(6months) = 381.5
49 + 38.75(12months) = 514
Difference in total cost = 514 -381.5 = $132.5
Answer:
Step-by-step explanation:
Given that in the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College.
Table is prepared as follows
Bus coll. Lib Arts coll Educ. coll Total
Observed 90 120 90 300
Expected p.c. 35 35 30 100
Expected number 105 105 90 300
Percent*300/100
Hence expected frequency for business college = 105
