Start by subtracting 2 from both side which gives you [-3x<9] then divide by -3 which gets you [x<-3] so the answer is B
Answer:
0.139
Step-by-step explanation:
We are given that
Total number of cards=52
n=18
We have to find the probability of drawing at least 7 spades
Total number of spaded in deck of 52 cards=13
Probability of getting spade=
Probability,
Probability of getting no spade=
By binomial theorem of probability
P(x
The probability of drawing at least 7 spades=
The probability of drawing at least 7 spades=0.139
Answer:
Step-by-step explanation:
In the 3rd question, we are given the equation x ^ 3 + x ^ 2 + 2x + 24. One of the factors is x + 3. Now, we can use long division to find that the equation we have left is x^2 - 2x - 8. We can just factor this to get (x - 4) (x + 2). In the 3rd question, possible factors for the coefficient are 1, 2, -1, -2. Possible factors for the constant are 1, 7, -1, -7. Now, we can try out all of them. The possible factors are 1, 7, -1, -7, 2, 14, -2, -14.
No, the functions shown are not inverses because the inverse for f(n)=-(n+1)^3would be f^−1(n)=−3√n−1.
