Question

3. ) Which of the following equations gives the relationship between S and T in the table below? (* means multiplication in the answers)

S	1	2	3	4	5	6
T	1	4	7	10	13	16

T = 2 – S

T = 4 – 3*S

T = 3*S +1

T = 3*S -2

None of the above

5. Given the following functions:

ceil(x)returns the smallest value as a decimal that is not less than x i.e. Round up

Examples: ceil(3.8) = 4.0 ceil(-2.3)= -2.0 ceil(2.3)= 3.0 ceil(-3.8) = -3.0

floor(x)returns the value of x rounded downward as a decimal

Examples: floor(3.8) = 3.0 floor(-2.3)= -3.0 floor(2.3)= 2.0 floor(-3.8) = -4.0

Given the following calculations

ceil(floor( 3.7) ) + floor( ceil( 3.7) ) (1)

ceil( ceil( 3.7 ) ) + floor( floor( 3.7) ) (2)

Which of the following statements about the above calculations is true?

(1) is greater than (2)

(2) is greater than (1)

(1) and (2) are equal
