Answer:
2.25
Step-by-step explanation:
divide
An inverse function is a function that reverses another function, so we have a function called:

Then, the inverse function will be as follows:

Given that

, we need to isolate x in terms of y:

∴

So:

and

therefore, exchanging variables x and y:

and


and

Which are the figures shown below.
Answer:
y=1/4x-1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-(-2))/(8-(-4))
m=(1+2)/(8+4)
m=3/12
m=1/4
y-y1=m(x-x1)
y-(-2)=1/4(x-(-4))
y+2=1/4(x+4)
y=1/4x+4/4-2
y=1/4x+1-2
y=1/4x-1
Independent, x-coordinate, input, domain.

Answer:
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Step-by-step explanation:
From the data, to produce a probability distribution for the data :
X : number of times blood is drawn ;
P(x) : probability that blood is drawn at X times
Hence, the probability distribution table for the data Given goes thus :
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Probability that blood is drawn 0 times = 6/15
Probability that blood is drawn 1 time = 5/15
Probability that blood is drawn 2 times = 3/15
Probability that blood is drawn 3 times = 1/15
(6/15 + 5/15 + 3/15 + 1/15) = 1
