Answer:
4.75x=54+2.5x x=24
Step-by-step explanation:
x=Number of games
4.75x=54+2.5x
Subtract 2.5x from both sides:
2.25x=54
Divide both sides by 2.25:
x=24

Answer:
The probability is 0.081
Step-by-step explanation:
Here, we want to calculate the probability that the 3rd inspection will be defective.
What this means is that the first two would
not be defective.
Probability of having a defective DVD = 10% = 10/100 = 0.1
Probability of not having a defective DVD = 1 -0.1 = 0.9
So the probability of third being defective = Probability of first not defective * Probability of second not defective * Probability of third defective
= 0.9 * 0.9 * 0.1 = 0.081
So if 199.75 is the cost after a 18% discount
The original price is 100%
Then the price after a 18% discount is
Tell me as a percentage
Answer:
(1, 0) and (3, 0)
Step-by-step explanation:
y=2x²-8x+6
x- intercept when y=0
- 2x²-8x+6=0
- x²-4x+4=1
- (x-2)²=1
- x-2=1 ⇒ x= 3
- x-2= -1 ⇒ x= 1
