The equation that represents the number of hours the plumber worked is

90(x) = 855.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, A plumber charges his customers $90 for each hour he works.

Assuming the no. of hours to be 'x'.

∴ The equation that represents the number of hours the plumber worked is

90(x) = 855.

Complete Question

The probability that a single radar station will detect an enemy plane is 0.65.

(a) How many such stations are required to be 98% certain that an enemy plane flying over will be detected by at least one station?

(b) If seven stations are in use, what is the expected number of stations that will detect an enemy plane? (Round your answer to one decimal place.)

Answer:

a

 [tex]n \approx 4[/tex]  

b

Step-by-step explanation:

From the question we are told that

The probability that a single radar station will detect an enemy plane is [tex]p =0.65[/tex]

 Gnerally the probability that an enemy plane flying over will be detected by at least one station is mathematically represented as

     [tex]P(X \ge 1 ) = 0.98[/tex]

=>   [tex]P(X \ge 1 ) = 1 - P(X < 1) = 0.98[/tex]

=>   [tex]P(X = 0) = 1 - 0.98[/tex]     Note [tex]P(X < 1) = P(X = 0)[/tex]

=>   [tex]P(X = 0) = 1 - 0.98[/tex]

=>   [tex]P(X = 0) = 0.02[/tex]

Generally from binomial probability distribution function

     [tex]P(X = 0) = ^nC_0 * p^{0} * (1- p)^{n- 0}[/tex]

Here C represents combination hence we will be making use of of combination functionality in our  calculators

Generally any number combination 0  is  1

So  

     [tex]P(X = 1) = 1 * 1* (1- 0.65)^{n- 0} = 0.02[/tex]

=>  [tex](1- 0.65)^{n- 1} = 0.02[/tex]

taking log of both sides

     [tex]log [(0.35)^{n- 1} ] = log (0.02)[/tex]

=>  [tex]{n- 1}log[0.35] = -1.699[/tex]

=>  [tex]{n- 1}* -0.4559 = -1.699[/tex]

=>  [tex]n= 3.7264 + 1[/tex]

=>  [tex]n= 4.7264[/tex]

=>  [tex]n \approx 4[/tex]  

Gnerally the expected number of stations that will detect an enemy plane is  

    [tex]E(X) = 7 * 0.65[/tex]

=> [tex]E(X) \approx4.5[/tex]

Known today as the Code of Hammurabi, the 282 laws are one of the earliest and more complete written legal codes from ancient times. The codes have served as a model for establishing justice in other cultures and are believed to have influenced laws established by Hebrew scribes, including those in the Book of Exodus.

Answer:

The Hammurabi Code is significant because it is one of the earliest complete written legal law codes that were used in the ancient times. The lasting impact is that the Hammurabi Code helped established the idea of legal laws and rules that will help shape society for the greater good. Also they helped served as a model for what laws we have and will continue to have.

Answer:

180 ft

Step-by-step explanation:

We are told that the scale model is 40:1. And that it's being used to conduct wind - tunnel tests.

This means 40 units represents 1ft.

This means that 4.5ft will be;

(4.5 × 40)/1 = 180 ft

Thus, the actual length of airplane would be 180 ft.

Selection of all the true statements:

A: dilations always increase the length of line segments.

B: Dilations take perpendicular lines to perpendicular lines.

C: Dilations of an angle are congruent to the original angle.

F: Dilations of a triangle are similar to the original triangle

Step-by-step explanation:

Dilations are transformations that enlarge or reduce a figure from its original shape and size to another that a bigger or smaller. Dilations create similar figures because multiplying by the scale factor creates proportional sides while leaving the angle measure and the shape the same.  This also implies that dilations of an angle are congruent to the original angle.

Answer:

The value is  [tex]P(Z' | N )= 0.92[/tex]

Step-by-step explanation:

From the question we are told that

   The proportion of defective widgets produced by older widget is  [tex]p = 23\% = 0.23[/tex]

  The proportion of defective widgets produced by new  widget is  

[tex]q = 0.08[/tex]

Generally since we are considering the new machine in this question it then mean that the probability that widget was defective given that it was produce by the new machine is

      [tex]P(Z | N ) = 0.08[/tex]

Here Z  is the event that the widget was defective

         N  is the even that the widget was produced by the new machine

Also  the probability that the widget was defective given that it was not produced by the new machine is  

      [tex]P(Z | N') = 0.23[/tex]

Generally  from the question the probability that the widget was produced by the new machine is mathematically represented as

      [tex]P( N) = \frac{3}{4}[/tex]

=>   [tex]P( N) = 0.75[/tex]

Generally the probability that the widget is defective  and that  it was produced by the new  is mathematically represented as

      [tex]P( Z\ n \ N) = P(Z | N ) * P(N)[/tex]

=>   [tex]P( Z\ n \ N) = 0.08 * 0.75[/tex]

=>   [tex]P( Z\ n \ N) = 0.06[/tex]

Generally the probability that the widget is defective and that  it was not produced by the new machine is

     [tex]P(Z\ n \ N') = P( Z | N' ) * [1 -P(N)][/tex]

=>   [tex]P(Z\ n \ N') = 0.23 * [1 -0.75][/tex]

=>   [tex]P(Z\ n \ N') =0.0575[/tex]

Generally the probability that the widget is defective is  

       [tex]P(Z) = P(Z \ n \ N) + P(Z \ n \ N')[/tex]

=>     [tex]P(Z) = 0.06 + 0.0575[/tex]

=>     [tex]P(Z) = 0.1175[/tex]

Generally the probability that the widget is not defective and it produced by the new machine is mathematically represented as

      [tex]P(Z' \ n \ N ) = P(N ) - P(Z \ n \ N)[/tex]

=>    [tex]P(Z' \ n \ N ) =0.75 - 0.06[/tex]

=>    [tex]P(Z' \ n \ N ) =0.69[/tex]

Generally the probability that the widget was produced by the new machine,given that a randomly chosen widget was tested and was found to be defective is mathematically represented as

       [tex]P(Z' | N ) =\frac{P(Z' \ n \ N)}{P(N)}[/tex]

=>     [tex]P(Z' | N )= \frac{0.69}{0.75}[/tex]

=>     [tex]P(Z' | N )= 0.92[/tex]

Answer:

The absolute difference between the two calculations is 0.2

Step-by-step explanation:

Student 1

When the events do not affect each other, they are known as independent events. That is, two events are independent if the result of the second event is not affected by the result of the first event.

When two events are independent, the probability that A and B occur is equal to the product of the probability that A occurs and the probability that B occurs. Then:

P(A∩B)= P(A)*P(B)

The probability of the opposite event is equal to 1 minus the probability of the  event. So in this case you have:

P(A'∩B')= 1 - P(A∪B)

Being P(A∪B)= 0.7, then:

P(A'∩B')= 1 -0.7

P(A'∩B')= 0.3

Being P(A)= 0.5 and P(A'), so

0.3= 0.5*P(B)

[tex]P(B')=\frac{0.3}{0.5}[/tex]

P(B')=0.6

Being P(B)= 1 - P(B') so P(B)= 1 - 0.6 and you get P(B)=0.4

Student 2

Two events are mutually exclusive when both cannot occur simultaneously. In other words, two events A and B are incompatible or mutually exclusive when they have no element in common. This is: P(A∩B)= 0

Being P(A∪B) =P(A) + P(B) - P(A∩B), P(A)=0.5 and P(A∪B)= 0.7, you get:

0.7=0.5 + P(B) -0

Solving:

0.7=0.5 + P(B)

0.7 - 0.5 = P(B)

0.2 = P(B)

Finally the absolute difference between the two calculations can be calcutated as:

|0.4 - 0.2|= 0.2

The absolute difference between the two calculations is 0.2
