Answer:
The inverse is 1/2x -3/2
Step-by-step explanation:
Set the equation equal to y
y = 2x+3
Exchange x and y
x = 2y+3
Solve for y
Subtract 3 from each side
x-3 = 2y+3-3
x-3 = 2y
Divide each side by 2
(x-3)/2 = 2y/2
1/2x -3/2 =y
The inverse is 1/2x -3/2
Answer:
20 x 30 + 11 - 8
Step-by-step explanation:
Answer: The question is incomplete, here is the complete question ;
Let X denote the distance (m) that an animal moves from its birth site to the first territorial vacancy it encounters. Suppose that for banner-tailed kangaroo rats, X has an exponential distribution with parameter ? = 0.01327. (a) What is the probability that the distance is at most 100 m? At most 200 m? Between 100 and 200 m? (Round your answers to four decimal places.
Step-by-step explanation:
- X = denote the distance (m)
- P (X > x) = exp( - 0.01342x)
- Therefore, P (X < = 100) = 1 - P (X > 100) = e-0.01342 X 100 = 0.2613 ; the probability that the distance is at most 100 m
- Similarly, P (X < =200) = e-0.01342 X 200 = 0.0683 ; At most 200 m
- P(100 < X <200) = 0.2613 - 0.0683 = 0.193 ; Between 100 and 200 m
the first one and the last one.
First, let's call "a number": n
Then. "eight less than a number" can be written as: n-8
This expression "is no more than 14" can be written as: n−8≤14
