Answer:
a) Figure attached
b)
Step-by-step explanation:
For this case we can find first the probability of being dfective on the shipment like this:
Since he select 10000 and 1000 of theme were defective.
Now we know that the inspector select 2 switches at random so then we can create the possible outcomes.
Part a
The tree diagram is on the figure attached, the sample space on this case is:
D = represent a defective switch
N= represent a non defective swicth
Part b
For this case we want the probability that both switches would be defective and on this case we can do this:
Assuming independent between the events.
length, width, and height are (b+2), (b-2), (b+3)
Step-by-step explanation:
Doing what the problem statement tells you to do, you get ...
(b^3 +3b^2) -(4b +12)
= b^2(b +3) -4(b +3) . . factor each pair of terms
= (b^2 -4)(b +3) . . . . write as a product
= (b -2)(b +2)(b +3) . . . . use the factoring of the difference of squares
The three factors are (b-2), (b+2), and (b+3). We have no clue as to how to associate those with length, width, and height. We just know these are the dimensions of the box.
Answer:
x=$2.50, y=$4.00
Step-by-step explanation:
Let x=cost of the water slide
Let y=cost of the ferris wheel
System of equations:
3x+3y=19.50
2x+3y=17.00
Subtract the 2nd from the 1st to get:
x=2.50
Now plug into first equation to get:
3(2.50)+3y=19.50 so y=4.00
Check in 2nd equation:
2(2.50)+3(4) = 5+12 = 17
