Answer:
-4 ; -1 ; 2 ; 5
Step-by-step explanation:
-4 is smaller because when counting from zero to the left it is descending but ascending numerically. 0 to -1 to -2 to -3 etc
After that you write the next numbers in ascending order
Answer:
THe expected annual cost is $282200
Step-by-step explanation:
We should take the base cost and sum it by the anual cost multiplied by 3, because the lifetime of the machines is 3 years. Since the expected return is 10%, then we have to multiply the result by 1.1, therefore
cost = (750000+12000*3)*1.1 = $864600
Now, we divide this by 3 to obtain the annual cost
Annual cost = 864600/3 = $288200
Answer: A symbol
Step-by-step explanation: Nothing in that picture gives a value for x
Answer:
The probability is 9/266
Step-by-step explanation:
The first thing to do here is get the total number of marbles = 5 + 7 + 9 = 21 marbles
Now we are drawing the marbles without replacement, this means once a marble is drawn there is a decrease in the total number of marbles left.
The probability of drawing a green marble initially = number of green marbles/ total
number of marbles = 9/21 = 3/7
Now, we want to draw a blue marble
There are 5 blue marbles and we have already drawn one marble from the total. So the probability of drawing a blue marble would be 5/20 = 1/4
And lastly, another green marble
That would make 6 green marbles left and a total of just 19 left. So the probability at this point for green marbles = 6/19
Having and in probability means we multiply all
So this means the probability we are calculating is; 3/7 * 1/4 * 6/19 = 18/(28 * 19) = 9/(14 * 19) = 9/266
