In which of the tables below x and y are inversely proportional? find the constant of variation.

can you tell me which ones are inversly and directly proportiional and the constant of variation for each :

a)

l x l 3 l 4 l 5 l5.5 l
l__l__l__l
l y l 8 l 6 l 4.8 l4 l
l__l__l__l

b)

x 0.1 0.5 75 100
y 300 60 0.4 0.3
(pretend thats a chart)

can you tell me which ones are inversly and directly inversable and the constant of variation for each :

The probability that a college student belongs to a health club is 0.3. the probability that a college student lives off-campus is 0.4. the probability that a college student belongs to a health club and lives off-campus is 0.12. find the probability that a college student belongs to a health club or lives off-campus. tip: p(a or b) = p(a) + p(b) - p(a and b) 0.54 0.58 0.70 0.82

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Adoctor administers a drug to a 38-kg patient, using a dosage formula of 50 mg/kg/day. assume that the drug is available in a 100 mg per 5 ml suspension or in 500 mg tablets. a. how many tablets should a 38-kg patient take every four hours? b. the suspension with a drop factor of 10 ggt/ml delivers the drug intravenously to the patient over a twelve-hour period. what flow rate should be used in units of ggt/hr? a. the patient should take nothing pills every four hours. (type an integer or decimal rounded to the nearest hundredth as needed.)
