Answer:
D. 3(x - 1)(x+3)(x + 2).
Step-by-step explanation:
3(x - 1)(x + 3)(x + 2)
= 3(x - 1)(x^2 + 5x + 6)
= 3(x^3 + 5x^2 + 6x - x^2 - 5x - 6)
= 3(x^3 + 4x^2 + x - 6)
= 3x^3 + 12x^2 + 3x - 18.
The probability it will take 20 minutes or more is about 6.3%.
Answer:
1.3455
Step-by-step explanation:
A 15% increase is a multiplication by 1.15
So a 15% and a 17% increase is a multiplication of 1.15*1.17 = 1.3455
Answer: Hence, the probability that he will get at least one lemon is 0.70.
Step-by-step explanation:
Since we have given that
Number of cars = 30
Number of lemon cars = 10
Number of other than lemon cars = 30-10 = 20
According to question, he bought 3 cars,
we need to find the probability that you will get at least one lemon.
So, P(X≤1)=1-P(X=0)=1-P(no lemon)
Here, P(no lemon ) is given by

so, it becomes,

Hence, the probability that he will get at least one lemon is 0.70.
