Alex was trying to determine how much money he owed the bank. Since his checking account has a balance of -155 dollars, he thinks that he can find the absolute value of -155 to determine that he owes the bank 155 dollars. Is Alex correct?
Answer:
Alex is correct.
Step-by-step explanation:
In order for Alex to get to $0, meaning he owes the bank nothing, he has to add 155 dollars to negative 155 dollars, because this means he has no debt left. The absolute value of -155 is 155 and if Alex pays the 155 dollars, he will not have to pay anything else to the bank.

its Algebra
Answer: The answer is D
Step-by-step explanation:
You add z to the other side then it will cancel out which then it would be (w+z) and then you times it by 2 by both sides which would be 2(w+z) and then you would subtract x from both sides which will be 2(w+z)-x

A restaurent pays a water R18 per hour in one week he worked a shift from 12h00 to 23h00 Calculate the number of hours the water works per shift
Answer:
Number of hour work per shift = 11 hour per day
Amount paid for one shift = Rs 198
Step-by-step explanation:
Given:
Amount pay per hour = Rs 18
Shift time = 12 h to 23 h
Find;
Number of hour work per shift
Amount paid for one shift
Computation:
Number of hour work per shift = 23:00 - 12:00
Number of hour work per shift = 11 hour per day
Amount paid for one shift = Number of hour work per shift x Amount pay per hour
Amount paid for one shift = 11 x 18
Amount paid for one shift = Rs 198

Answer:
D: (2, -3)
Step-by-step explanation:
We have;
y = 3x - 9 - - - (1)
y = -2x + 1 - - - (2)
By substitution method, from eq 1, we see that: y = 3x - 9
Thus,let's put 3x - 9 for y in eq 2;
3x - 9 = -2x + 1
Rearranging to get;
3x + 2x = 9 + 1
5x = 10
x = 10/5
x = 2
Thus;
y = 3(2) - 9
y = 6 - 9
y = -3
Thus,the solution (x, y) = (2, - 3)
Double Dice is a game in which two dice are rolled. A player wins the game if a certain sum is rolled. A player wins $7.00 if he rolls a sum of 5 or 6 and $20.00 if he rolls a sum of 2 or 3. He wins nothing if any other sum is rolled.
A. Define the random variable, X.
B. Write out the probability distribution function for the game.
C. What is the expected value of the game?
D. Assuming you have to pay $6.00 to play the game, explain what happens in the long run. (Is it a good idea to play the game?)
Answer:
3.417
Kindly check explanation
Step-by-step explanation:
X : $7 ; $20 ; $0
Sample space for the sum of two die rolls :
Probability of obtaining a sum of 5 or 6 ;
P(sum of 5 or 6) = 9/36 = 1/4
Probability of obtaining a sum of 2 or 3 ;
P(Sum of 2 or 3) = 3/36 = 1/12
Probability of obtaining a sum of other Tha 2,3, 5 or 6 ; = 24/ 36 = 2/3
The probability distribution :
X _____ 0 _______ 7 _____ 20
P(x) ___ 2/3 _____ 1/4 ____ 1/12
Expected value of the game ; E(X) ;
E(X) = Σx*p(x)
E(X) = (0*2/3) + (7*1/4) + (20*1/12)
E(X) = 0 + 1.75 + 1.6667
E(X) = 3.417
This means that if the game is paid for a long time, the mean or expected winning will be ; $3.417
If game has to be played with $6 ; then to determine if it is a good idea to play the game on a long run, we calculate the payoff ;
The payoff is :
Expected value - playing cost
$3.417 - $6 = - $2.583
Since payoff is negative, we can conclude that it is not a good idea to play the game in the long run : as the expected value is lesser than the playing fee.

A box is filled with several party favors. It contains 12 hats, 15 noisemakers, 10 finger traps, and 5 bags of confetti. Let H = the event of getting a hat. Let N = the event of getting a noisemaker. Let F = the event of getting a finger trap. Let C = the event of getting a bag of confetti. Find P(N).
Answer:
P(N) = 5/14
Step-by-step explanation:
Find P(N) by finding the probability of getting a noisemaker.
There are 42 items in total, and 15 are noisemakers. Find the probability by dividing 15 by 42:
15/42
Simplify:
5/14
So, P(N) = 5/14
