The answer to this question would be: 2*52! -1
In this case, the card is either picked up by Naoko or they are not picked up. That means there are two possible outcomes for each card. For 52 card, the possibility should be:
2*52!
If Naoko needs to pick at least one, the possibilities become one less because "no card picked" possibility is ruled out
A.T.Q, equations will be:
x+y = 450
2x+5y= 1800
Substitute value of x from equation (1), in equation (2)
2(450-y) +5y=1800
900-2y+5y=1800
3y=900
y=300
so, your answer is 300
Answer:
Step-by-step explanation:
Here you go mate
Step 1
8.6(x – 1) + 8x Equation/Question
Step 2
8.6(x-1) + 8x Simplify
8.6x+-8.6+8x
Step 3
8.6x+-8.6+8x Combine the terms
(8.6x+8x)+(-8.6)
Step 4
(8.6x+8x)+(-8.6) Add them
Answer
16.6x-8.6
