Answer:
The value of the car will be x - (0.15)x after a year.
Step-by-step explanation:
The car was 15% more when it first came out, and the price went down by 15% after a year.
Therefore, to solve this problem, we need to multiply 0.15 by the initial cost, which will tell you how much the car price decreased.
Then, we need to subtract this amount from x, or the initial cost, in order to find how much the car will be worth after a year.
Therefore, the value of the car will be x - (0.15)x after a year.
Hope this helps! :D
Answer:180 is what it need to be
Step-by-step explanation:
Since the denominator of any fraction can’t =0, then 3x-4 can’t = 0. What will make that 0? Let’s see: 3x-4=0. 3x=4. X= 4/3. Everything else will work!
Answer:
1/18
Step-by-step explanation:
We are considering that we have 2 dices with 6 faces each (so, the probability to getting any face in any dish is 1/6). To get an 11, we only have two ways to obtain it:
Dice 1= 6 and Dice 2 =5 or Dice 1= 5 and Dice 2 =6
So, the probability of the event is given as:
P(Dice1=5 ∧ Dice2=6) ∪ P(Dice1=6 ∧ Dice2=5) = P(Dice1=5) x P(Dice2=6) + P(Dice1=6) x P(Dice2=5) = 1/6 x 1/6 + 1/6 x 1/6 = 1/36 + 1/36 = 2/36 = 1/18.
As 1/18 = 0,055, and 0,055 > 0,05, we consider the event as not significative (according to the definition of significance in the sentence).
Answer:
The inverse function is 3x+2
Step-by-step explanation:
To get the inverse function exchange x and y and then solve for y
y = (x-2)/3
Exchange x and y
x = (y-2)/3
Solve for y
Multiply by 3
3x = 3/3 *(y-2)
3x = y-2
Add 2 to each side
3x+2 = y-2+2
3x+2 =y
The inverse function is 3x+2
