Can you help me to do this please?Finding the inverse of each function

marusya05 [52]

Let

$y=-\frac{3}{x+1}+2$

Find the equation in terms of y in the form x = f(y).

$\begin{gathered} y-2=\frac{-3}{x+1} \\ x+1=\frac{-3}{y-2} \\ x=\frac{-3}{y-2}-1 \end{gathered}$

Replace y by x in the right hand side, which will be the required inverse of the function.

$g^{-1}(x)=-\frac{3}{x-2}-1$

A long distance telephone company offer two plans . The deluxe plan cost $30 a month and offers unlimited long distance calling.

Gnesinka [82]

Answer:

399 minutes a month

Step-by-step explanation:

As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.

The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).

The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.

Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.

According to exit polling from the 2014 U.S. midterm elections, 36% of voters had a household income less than $50,000, while 64

Veseljchak [2.6K]

Answer:

0.6946 = 69.46% probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Republican

Event B: From a household that makes at least $50,000.

Probability of Republican:

43% of 36%(makes less than $50,000).

55% of 64%(makes more than $50,000).

$P(A) = 0.43*0.36 + 0.55*0.64 = 0.5068$

Republican and from a household that makes at least $50,000.

55% of 64%. So

$P(A \cap B) = 0.55*0.64 = 0.352$

What is the probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.352}{0.5068} = 0.6946$

0.6946 = 69.46% probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000.
