keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

\(y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{3}}x+1\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}\)

so we're really looking for the equation of a line whose slope is 1/3 and that it passes through (-6 , 8)

\((\stackrel{x_1}{-6}~,~\stackrel{y_1}{8})\hspace{10em} \stackrel{slope}{m} ~=~ \cfrac{1}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{ \cfrac{1}{3}}(x-\stackrel{x_1}{(-6)}) \implies y -8= \cfrac{1}{3} (x +6) \\\\\\ y-8=\cfrac{1}{3}x+2\implies {\Large \begin{array}{llll} y=\cfrac{1}{3}x+10 \end{array}}\)

a.) The probability that the girls play at least 3 games is 0.36.

b.) The probability that the girls play 5 games is 0.1024.

c.) On the second day the girls are expected to play more games of Monopoly.

Probability is the branch of discrete mathematics. It is used for calculating how likely an event is to occur or happen.

We know that,    P ( E )   +   P ( \(E^{'}\) )    =   1

         where,     P ( E )  =   Probability of possible outcomes

                           P ( \(E^{'}\) ) =  Probability of impossible outcomes

                   ⇒    P ( E )   =   1   -   P ( \(E^{'}\) )        →  1

a.) Probability that the girls play at least 3 games

                          P ( E )   =   1   -   P ( \(E^{'}\) )  

                                       =   1   -   ( 2/5 + 3/5 × 2/5 )

                                       =   1   -   ( 0.4 + 0.6 × 0.4 )

                                       =   1   -   ( 0.64 )

                          P ( E )   =  0.36    

b.) Probability that the girls play 5 games

                           P ( E )   =    ( 5 1 )  ×  0.2  ×  \((0.8)^{3}\)  ×  0.2

                                        =    ( 5 1 )  ×  0.2  ×  0.512  ×  0.2

                                        =    ( 5 1 )  ×  0.02048

                           P ( E )    =    0.1024

c.) The day on which girls played more games of monopoly

⇒ Number of games to be played on the first day   =   1 / 0.4

                                                                                     =   2.5

⇒ Number of games to be played on the second day   =   2 / 0.2

                                                                                            =   10

Therefore, 0.36 is the probability that the girls play at least 3 games, 0.1024 is the probability that the girls play 5 games and the girls are expected to play more games of Monopoly on the second day.

The surface area of that part of the plane 10x+7y+z=4 that lies inside the elliptic cylinder \(\frac{x^2}{25} +\frac{y^2}{9}\) is 15π√150 and this can be determined by using the given data.

We are given the two equations are:

10x + 7y + z = 4---------(1)

\(\frac{x^2}{25} +\frac{y^2}{9} =1-------------(2)\)

equation(1) is written as

z = 4 - 10x - 7y-----------(3)

The surface area is given by the equation:

A(S) = ∫∫√[(∂f/∂x)² + (∂f/∂y)² + 1]dA------------(4)

compare equation(4) with equation(3) we get the values of ∂f/∂x and

∂f/∂y

∂f/∂x = -10

∂f/∂y = -7

substitute these values in equation(4)

A(S) = ∫∫√[(-10)² + (-7)² + 1]dA

A(S) = ∫∫√[100 + 49 + 1]dA

A(S) = ∫∫√[150]dA

A(S) = √150 ∫∫dA

Where ∫∫dA is the elliptical cylinder

From the general form of an area enclosed by an ellipse with the formula;

comparing x²/a² + y²/b² = 1  with x²/25 + y²/9 = 1, from that we get the values of a and b

a = 5 and b = 3

So, the area of the elliptical cylinder = πab

Thus;

A(S) = √150 × π(5 × 3)

A(S) = 15π√150

Answer:

Dilation of 3

Step-by-step explanation:

Total number of people = (4 classes x 23 students x 3 adults) = 276 people
Number of buses = 5
So, the numbers of people on each bus = 276/5 = 55.2
Since the number of people on each bus must be a whole number, we need to round up to the nearest whole number, which is 56. Therefore, there will be 56 people on each bus.

First, let's find the total numbers of people going on the field trip:

There are 4 classes with 23 students and 3 adults each, so there are 26 people per class (23 students + 3 adults). Since there are 4 classes, we have a total of 4 * 26 = 104 people.

Now, let's divide the total number of people by the number of buses to find out how many people will be on each bus:

104 people / 5 buses = 20.8 people per bus

However, we cannot have a fraction of a person on a bus, so the solution must belong to the set of natural numbers. In this real-world context, having 20.8 people on each bus is not a valid solution, as it is not a natural number.

Therefore, the correct answer is:
C. Because of the real-world context, the solution must belong to the set of all natural numbers. Therefore, the solution is unacceptable.  The statement that must be true about the solution is C. Because the real-world context involves a group of 4th-grade students and their teachers, the solution must be a whole number, since we cannot have a fraction of a person and the solution must belong to the set of all natural numbers, and any solution that is not a natural number would be unacceptable.

Answer:

The second train speed is 356.4 miles per hour

And, the first train speed is  361 miles per hour

Step-by-step explanation:

The computation of the speed of each train is as follows

Given that

The Sum of the speed of two trains is 717.4 miles per hour

Let us suppose the second train speed be x

So for the first train, the speed is x + 4.6

Now the equation is

x + x + 4.6 = 717.4

2x + 4.6 = 717.4

2x = 717.4 - 4.6

2x = 712.8

x= 356.4

Therefore the second train speed is 356.4 miles per hour

And, the first train speed is = 356.4 + 4.6 = 361 miles per hour

A "required parameter" requires an assigned value for the argument used to call the method, while "optional parameters" do not need to be included in the method call and have a default value assigned to them.

The type of parameter that requires that the argument used to call the method must have an assigned value is a "required parameter".

Required parameters are parameters that must be included in the method call, and the argument passed for the required parameter must have a value assigned to it. If a required parameter is not included in the method call, or if the argument passed for the required parameter does not have a value assigned to it, an error will be thrown.

In contrast, there are also optional parameters, which are parameters that do not need to be included in the method call. If an optional parameter is not included in the method call, the method will use a default value assigned to the parameter.

In many programming languages, the syntax for specifying required and optional parameters in a method or function call is specified using different symbols, such as parentheses or square brackets.

This expression gives us a present value of approximately $1,376,500.

To calculate the present value of John Doe's winnings, we need to find the present value of each individual payment and then sum them up.

The formula to calculate the present value of an annuity is:

PV = C * (1 - (1 + r)^(-n)) / r

Where PV is the present value, C is the annual payment, r is the discount rate, and n is the number of periods.

In this case, John Doe will receive $100,000 each year for 30 years, and the discount rate is 6%. Plugging these values into the formula, we get:

PV = $100,000 * (1 - (1 + 0.06)^(-30)) / 0.06

Calculating this expression gives us a present value of approximately $1,376,500.

To find this answer you do the equation:

630/30 = ?

This equals 21.

Therefore, her hourly rate is $21 per hour.

Answer:

n 1 week, she worked 30 hours. So, she earned $630 for 30 hours. The hourly rate is then 630 / 30 = 21.

The amount of petrol consumed in one hour will be 200 liters.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

In 45 minutes, an automobile uses 150 gallons of gasoline.

Consequently, the rate of gasoline consumption in liters per minute will be

= 150 / 45

= 10 / 3  Liters per minute

We are aware that an hour is made up of 60 minutes.

The amount of gasoline that will be used in an hour will then be

= (10 / 3) x 60

= 10 x 20

= 200 liters

Thus, 200 liters of gasoline will be burned in an hour.
