Complete the steps in order to write the inverse of f(x) = x + 5
rusak2 [61]

Answer:

see the procedure

Step-by-step explanation:

we have

f(x)=x+5

step 1

Let

y=f(x)

y=x+5

step 2

Exchange the variables

x for y and y for x

x=y+5

step 3

Isolate the variable y

y=x-5

step 4

Let

f^{-1}(x)=y

f^{-1}(x)=x-5

The table shows the record low temperatures for several states. Graph the temperatures on a number line.
OlgaM077 [116]

Step-by-step explanation:

Please find the attachment.

We have been given a table that shows the record low temperatures for several states. We are asked to graph the temperatures on a number line.

First of all we will draw a number line going to infinity into both directions.  

To graph the given temperatures on number line let us arrange temperatures in less negative order.  

-34, -32, -30, -29, -27.  

Since we know that numbers with large negative values lie on the left at number line. Let us graph our large negative temperature on the left at our number line.      

We can see that -34 is the most negative temperature, therefore, it will be on the left most side of our number line.  

-27 is greatest of our given negative temperatures. -27 is less negative temperature than our other given low temperatures, therefore, it will lie on the right most side of our number line.  

Other temperatures will lie between these two values according to their temperatures.    

-32 is second large negative temperature after -34, therefore, it will lie on the right side of -34.

-30 will lie on the right side of -32 and -29 will lie on the right of -32.

The interior angles of a triangie have measures 100° (4y + 25) ° , and (3y + 20) What is the value of y?
Mama L [17]

Answer:

since the sum of all angles of a triangle is 180°

Step-by-step explanation:

so 100°+4y+25°+3y+20=180°

145°+7y=180°

7y=180°-145°

7y=35°

y=5°

A family has j children with probability pj , where p1 = .1, p2 = .25, p3 = .35, p4 = .3. A child from this family is randomly c
aliya0001 [1]

Answer:

A) the conditional probability that the has only 1 child = 0.24

B) The conditional probability that the family has only 4 children = 0.18

Step-by-step explanation:

To answer the questions, we first start with defining each event. Let E be the event that the child selected is the oldest and let Fj be the event that the family has j children.

From this, we can deduce that the probability that the child is the oldest, given that there is j children is ; P(E | Fj ) = 1/j.

In addition, we know P(Fj ) = pj as given in the problem. In answering the 2 questions, we seek the probability P(Fj | E). Thus, by the Bayes’s formula;

P(Fj | E) = P(EFj )/P(E) which gives;

P(Fj | E) = {P(E | Fj )P(Fj )} / {Σ(4,i=1)P(E | Fj )P(Fj )}

= (1/j)/ Σ(4,i=1)(1/j)pj

= ((pj)/j) / {p1 + (p2)/2 + (p3)/3 +(p4)/4}

Therefore, the conditional probability that the family has only 1 child; P(F1 | E) = p1 / {p1 + (p2)/2 + (p3)/3 +(p4)/4} = 0.1/ (0.1 + (0.25/2) +(0.35/3) + (0.3/4) = 0.1/0.4167 = 0.24

The conditional probability that the family has only 4 children =

{(p4)/4} / {p1 + (p2)/2 + (p3)/3 +(p4)/4} = (0.3/4)/ (0.1 + (0.25/2) +(0.35/3) + (0.3/4) = 0.075/0.4167 = 0.18
