Answer:
A. fixed ratio
Step-by-step explanation:
Here worker is paid a fixed amount of $25 for every 20 chimes that she builds ( work quantity is also fixed). Therefore, the of reinforcement on which she is paid is Fixed ratio. In this schedule the reinforcement is done after a completion a fixed number of responses which 20 here. And in every cycle of reinforcement number of responses remain the same.
Answer:
The function is positive at . The function has no zeros. The function is undefined at x= -4.
Step-by-step explanation:
The given function is
It is rational function. The numerator is constant and the degree of denominator function is 2, therefore the value of denominator is always positive for any value of x.
Therefore the function is positive for any real value of x. The function is positive at .
To find the zeros we have to equate numerator equal to 0.
Since this statement is false for all values of x, therefore the function has no zeros.
Equate denominator equal to 0.
The number -4 divides the number line into two parts and .
Since at x=-4 the value of the denominator is equal to 0 and the function is not defined.
34,669 to the nearest thousand is 35,000 because you look at the number to the right of that place value. less than 5, round down. 5 and up, round up.
Subsitte
y=6-x and y=x-2
both equal y so set equal;
6-x=y=x-2
6-x=x-2
add x both sides and addd 2
8=2x
divide 2
4=x
sub back
y=6-x
y=6-4
y=2
(x,y)
(4,2)
answer is C
