Answer:
It doesn’t matter
Step-by-step explanation:
Latitude and longitude each refer to their own direction so noting the direction is useless. Yes, the number comes first.
Answer:
Step-by-step explanation:
f(x) = y = 3x/(8 + x) (I am assuming that the 8 + x is the denominator. Please use parentheses in the future if you forgot this. If there are no parentheses, then my solution will not work for you.)
Exchange x and y; that is, replace x by y and y by x simultaneously:
x = 3y/(8 + y).
Then use algebra to solve for y in terms of x:
(8 + y)x = 3y (multiply both sides by the denominator to clear the fraction)
8x + xy = 3y (distribute)
xy − 3y = −8x (rearrange terms with all y's on the left side of the equation)
y(x − 3) = −8x (factor out y as a common factor)
y = −8x/(x − 3) (divide by x − 3)
Finally, replace y by f-1(x):
f-1(x) = −8x/(x − 3).
This is the inverse of f(x). It can be checked by finding f(f-1(x)) and f-1(f(x)), and verifying that both equal x after simplifying.
Answer:
The probability that a customer purchases a black SUV is 0.05.
Step-by-step explanation:
<em>The question is incomplete:</em>
<em>At a certain car dealership, the probability that a customer purchases an SUV is </em><em>0.20</em><em>. Given that a customer purchases an SUV, the probability that it is black is </em><em>0.25</em><em>.</em>
The probability that a customer purchases a black SUV can be calculated as the multiplication of this 2 factors:
- The probability of a customer purchasing a SUV: P(SUV).
- The probability that it is black, given that he or she purchases a SUV (conditional probabilty): P(B|SUV)
We know then:
We can now calculate the probability as:
Y = 2x-6
Just move the y to the other side (add y so it gets pushed to the right) then subtract the six from the right to the left side.
