Answer:
(Second Option) = g of x equals the quantity x squared minus 5x plus 7 end quantity divided by the quantity x minus 3 end quantity
Step-by-step explanation:
A rational function contains a polynomial in both the numerator and the denominator. This answer fits that requirement.
9n - 13 = -48
+13
9n = -35
/9 /9
N= -3.888
The probability is 0.0334.
We will first find the probability that none of the 30 people sampled are infected. Since the probability of one person being infected is 0.00114, the probability that someone is not infected is 1-0.00114 = 0.99886. The probability that none of the 30 people are infected would be (0.99886)^30 = 0.966359. We subtract this from one to find the probability that at least one person is infected:
1 - 0.966359 = 0.0334.
Answer:
f(x) = 2x
Step-by-step explanation:
Remark
What I'm about to do is probably not the best way to do this question, but it is right. The plan is to take out a common factor on the right of f(x - 2) and then derive f(x) from that.
Solution
- f(x - 2) = 2x - 4 Take out a common factor on the right of f(x -2)
- f(x - 2) = 2(x - 2) Now what that means is that in the original equation, wherever you saw an x, you put in x - 2. So the original equation must have been
Check
- f(x) = 2x To check this put x - 2 back in
- f(x - 2) = 2(x -2) Remove the brackets.
- f(x - 2) = 2x - 4 which is what it should be.
Answer:
|8|
Step-by-step explanation:
Let the integer = x
x = - 2x - 24
x + 2x = - 24
3x = - 24
x = - 24/3
x = - 8
Hence, the integer is - 8
The number could be the positive of negative of 8
Hence, it is better expressed as |8|
