12. Suppose a reward for a CS follows a probabilistic schedule. If the probability of receiving the reward increases then: a) firing will increase for CS and increase for US b) firing will increase for CS and decrease for US c) firing will decrease for CS and decrease for US d) firing will decrease for CS and increase for US e) none of the above; firing will remain unchanged for CS and US
Answer:
d) firing will decrease for CS and increase for US
Step-by-step explanation:
The is the answer going by the probabilistic nature of the schedule. That is, as the probability of relieving reward increase has a direct effect on the CS leading to its decrease as well as a proportional increase for US. On the other hand, a decrease of probability of receiving reward will have an opposite effects on the schedule.

Ken earned $128 from his part-time job this summer. He spent 25% of his money on games. He is going to donate 1/6 of the remaining money to charity. How much will the charity receive?
A) $15
B) $16
C) $32
D) $80
Please explain how to do it also
Answer:
B) $16
Step-by-step explanation:
Alright so first you want to take the total amount of money made :
$128
Next you want to find 25% of this number (or 1/4) and subtract it from the total.
So :
128 / 4 = 32
So now we take 128 and subtract 32. (32 = 1/4 or 25% of 128)
128 - 32 = 96
Ken now has $96 left over after spending money on games.
So now that we have this number we need to find 1/6 of it because he took 1/6 of the money after he bought games and put it towards charity.
So :
96 / 6 = 16
16 is equal to 1/6 of his leftover money after games and is the amount the charity received.
B) $16
I hope this helps! :)
If you are confused or have any questions please comment or dm and I would be happy to help.
Also change the pfp FeelsGoodMan
Answer:
B) $16
Step-by-step explanation:
1. First let's find how much he spent on games. Multiply 0.25 to 188. 0.25 x 128 = 32.
2. Now subtract that amount from the original $128. 128 - 32. = 96.
3. Then, multiply 1/6 from 96. 1/6 x 96 = 16. This $16 is the amount the charity will receive.

A oil well is drilled at -175 meters ever 12 hours . How deep is the well after 15 hours of constant work. Numeric answers only
Answer:
-37.5 m
Step-by-step explanation:
If we assume that "one full day" is 24 hours, then 15 hours represents the fraction 15/24 of a day. Since the drilling rate was constant, and was presumed to start from a height of 0, the height after 15 hours is that fraction of the day's work:
... (15/24)×(-60 m) = -37.5 m
Answer:
-218.75
Step-by-step explanation:
you probably don't need the answer anymore but I still thought I should put it out there
150 into the ratio 4:11
9514 1404 393
Answer:
40 : 110
Step-by-step explanation:
There are a number of ways you can go at this. One of my favorite is to consider the value of a "ratio unit." Here, a total of 4+11 = 15 "ratio units" represent the total to be divided: 150. So the value of each one is ...
150/15 = 10
Then the division is ...
4 : 11 = 10·4 : 10·11 = 40 : 110
_____
Alternate solution
Let x represent the larger share. Then the ratio is ...
(150 -x) : x = 4 : 11
Cross-multiplying gives ...
11(150 -x) = 4x
1650 = 15x . . . . . add 11x, simplify
110 = x . . . . . . . . . divide by 15; the larger share
150-x = 150-110 = 40 . . . . . . the smaller share
The division is 40 : 110.

Gentry Industries has the following information about maintenance costs in the past six months.
Month Machine _Hours Amount
January 200 $2,800
February 350 3,000
March 450 4,000
April 500 5,000
May 600 5,200
June 580 5,800
How much would Gentry pay if maintenance machine hours are 550?
Answer:
Total cost= $5,425
Step-by-step explanation:
Giving the following information:
Month Machine _Hours Amount
January 200 $2,800
February 350 3,000
March 450 4,000
April 500 5,000
May 600 5,200
June 580 5,800
First, we need to calculate the fixed and variable costs. To do it, we will use the high-low method:
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (5,800 - 2,800) / (600 - 200)
Variable cost per unit= $7.5 per hour
Fixed costs= Highest activity cost - (Variable cost per unit * HAU)
Fixed costs= 5,800 - (7.5*600)
Fixed costs= $1,300
Fixed costs= LAC - (Variable cost per unit* LAU)
Fixed costs= 2,800 - (7.5*200)
Fixed costs= $1,300
Now, we can determine the total cost for 550 hours:
Total cost= 1,300 + 7.5*550
Total cost= $5,425

What is the length of side s of the square shown below?
45
90°
A. 2-2
B. 2
C. 42
O D. v2
E. 1
O F. 4
Answer:
D. √2
Step-by-step explanation:
Solve for x by applying trigonometric ratio.
Reference angle = 45°
Hypotenuse = 2
Adjacent side = s
Thus:
Cos (45) = adj/hyp
Cos (45) = s/2
2×Cos(45) = s
2 × √2/2 = s (cos (45) = √2/2)
√2 = s
s = √2
