Answer: B
hope this helps :)
True because the cost economics is an economic model that includes the cost of negative
Rates of operant responding are <u>higher</u> for fixed-ratio than for fixed-interval schedules; they are <u>higher</u> for variable-ratio then for variable-interval schedules.
Rates of operant responding are higher for fixed-ratio because on the interval contingency the higher response rates observed on ratio than on matched interval reward schedules has been assigned to the differential reinforcement of longer inter-response times (IRTs).
In the fixed-ratio schedule, as the ratio increases, resistance to extinction increases. On the other hand, in the fixed-interval schedule, resistance to extinction increases as the interval lengthens in time.
Hence, rates of operant responding are higher for fixed-ratio and for variable-ratio.

Answer:510 students
Explanation: given that total student is 850
And Of every 10 student 6 will have to sit for a refresher math course
Hence the number that will need a refresher math course will be (850/10)*6= 510
Or better still to better understand this let's use the crossing multiplication method
of 10 student 6must do a refresher math then
Of 850 students x must do a refresher math
Cross multiplying we have
X=(850*6)/10=510 students
