For each of the following pairs of variables, indicate whether you would expect a positive correlation, a negative correlation, or a correlation close to 0. (a) Maximum daily temperature and cooling costs.
(b) Interest rate and number of loan applications.
(c) Hours studied and grade on test.
(d) Price of soda and amount of soda purchased.
(e) Height and hours slept.
(f) Score on the math section of the SAT exam and score on the verbal section of the same test.
(g) Time spent on homework and time spent watching television during the same day by elementary school children.
(h) Amount of fertilizer used per acre and crop yield. (Hint: As the amount of fertilizer is increased, yield tends to increase for a while but then tends to start decreasing.)

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

answer: (3,11) is your answer.

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.
