Answer:
The probability is 0.31
Step-by-step explanation:
To find the probability, we will consider the following approach. Given a particular outcome, and considering that each outcome is equally likely, we can calculate the probability by simply counting the number of ways we get the desired outcome and divide it by the total number of outcomes.
In this case, the event of interest is choosing 3 laser printers and 3 inkjets. At first, we have a total of 25 printers and we will be choosing 6 printers at random. The total number of ways in which we can choose 6 elements out of 25 is 
, where 
. We have that 
Now, we will calculate the number of ways to which we obtain the desired event. We will be choosing 3 laser printers and 3 inkjets. So the total number of ways this can happen is the multiplication of the number of ways we can choose 3 printers out of 10 (for the laser printers) times the number of ways of choosing 3 printers out of 15 (for the inkjets). So, in this case, the event can be obtained in 
So the probability of having 3 laser printers and 3 inkjets is given by

Answer:
240
Step-by-step explanation:
lets see
if we sell 100 cups of lemonade that would make 200 dollars NOT ENOUGH
if we sell 100 cups of orange juice that would make 300 TOO MUCH
meaning we have the find the right one
lets say if we sell 80 lemonade cups we would make 160 then have 20 orange juice which would make 60 and 160+60= 220 so not enough either
this means we can't have as much lemonade
lets try 75 cups of lemonade
lets say if we sell 50 lemonade cups we would make 100 then have 50 orange juice which would make 150 and 150+100= 250 so too much
lets try 55 cups of lemonade
lets say if we sell 55 lemonade cups we would make 110 then have 45 orange juice which would make 135 and 110+135= 145
sooo close
try 60
60*2-120 40*3-120
120*120= 240
Answer:
The perimeter of parallelogram PQRS = 
⇒
2nd answer
Step-by-step explanation:
* <em>Lets revise some properties of the parallelogram</em>
- Each two opposite sides are parallel
- Each two opposite sides are equal
- Its <em>perimeter</em> is the <em>twice the sum of two adjacent sides</em>
* <em>Lets solve the problem</em>
∵ PQRS is a parallelogram
∵ The length of side SR is 
∵ The length of side QR is 
∵ <em>SR and RQ are two adjacent sides</em>
∵ The perimeter of parallelogram PQRS = 2(RQ + SR)
∴ The perimeter of parallelogram PQRS = 
∵ 
= 
∵ 
= 
∴ The perimeter of parallelogram PQRS =
Answer:
3.8
Step-by-step explanation:
"Let the art prints be p
Cost function is 38 + 2p
Revenue function is 12p
Set cost equal to revenue
12p = 38 + 2p
Subtract 2p from each side
10p = 38"
