20 POINTS!! can someone please help me? i will give brainiest to the right answer.

Answer:

Step-by-step explanation:

The rate of the change of the car is is its speed.

Speed = distance/time

Given

Distance = 27x³-9x²+3x

Time = 3x hours

Speed =  27x³-9x²+3x/3x

factor out 3x from the numerator:

Speed = 3x(9x²-3x+1)/3x

Speed = 9x²-3x+1

Hence the rate of the car is 9x²-3x+1

Answer:

45=2w+L and L=2w+5          

45=2w+L                                  45=2w+(2w+5)

                                                45=4w+5

                                                40=4w

                                                10=w                  

L=2w+5                                    L=2(10)+5

                                                L=20+5

                                                L=25                        

The length of the patio is 25 feet and the width of one side of the patio is 10 feet. Because there are two width sides and one length side, this all adds up to be 45 feet long.

Answer: 0.0496

Step-by-step explanation:

If events are said to be independent it means that the probability of one happening does not affect the probability of the other.

In calculating the probability that an employee is both male and a drug user using independent events, multiply the probabilities of the individual events to find the probability of the the events happening together.

P(A) * P(B) = P(A and B)

0.08 * 0.62 = 0.0496

Probabilities are used to determine the chances of events.

The probability that a randomly chosen employee is a male drug user is 0.0496

Represent the two events as A and B, such that:

[tex]P(A) = 0.08[/tex]

[tex]P(B) =0.62[/tex]

So, the probability that a randomly chosen employee is a male drug user is calculated as:

[tex]P(A\ and\ B) =P(A) \times P(B)[/tex]

This gives

[tex]P(A\ and\ B) =0.08 \times 0.62[/tex]

Multiply

[tex]P(A\ and\ B) =0.0496[/tex]

Hence, the probability that a randomly chosen employee is a male drug user is 0.0496

Answer:

a. [tex]\frac{5x}{(x+3)}[/tex]

b. [tex]\frac{5x}{(x+3)}[/tex]

Step-by-step explanation:

Given that:

a. [tex](\frac{25x^{2} }{2x+6})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{50x^{2} }{5x(2x+6)}[/tex]

                        = [tex]\frac{50x^{2} }{10x^{2} +30x}[/tex]

                        = [tex]\frac{(50x)x}{(10x+30)x}[/tex]

                        = [tex]\frac{50x}{(10x+30)}[/tex]

                         = [tex]\frac{5x}{(x+3)}[/tex]

b. [tex](\frac{25x^{2} }{2(x+3)})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{50x^{2} }{10x(x+3)}[/tex]

Answer:

a

      [tex]P(U |D ) = 0.198 [/tex]

b

   [tex]P(O\ n \ B) = 0.188[/tex]

c

  [tex]P(O | B) =   0.498 [/tex]

Step-by-step explanation:

The total number of deaths is mathematically represented as

      [tex]T   =  16 +  23 + \cdots  +  16[/tex]

        [tex]T   =623 [/tex]

The total number of deaths in 1996 - 2000 is mathematically represented as

     [tex]T_a =  16 +  23+ \cdots + 30[/tex]

      [tex]T_a = 235 [/tex]

The total number of deaths in 2001 - 2005 is mathematically represented as

     [tex]T_b =  17 +  16 + \cdots + 23[/tex]

      [tex]T_b = 206 [/tex]

The total number of deaths in 2006 - 2010 is mathematically represented as

     [tex]T_c =  15 +  17 + \cdots + 16[/tex]

      [tex]T_d = 182 [/tex]

Generally the the probability that it would occur under the tree given that the death was  after  2000 is mathematically represented as

     [tex]P(U |D ) = \frac{P(A \ n\  U )}{P(A)}[/tex]

Here  [tex]P(A \ n\  U )[/tex] represents the probability that it was after 2000 and it was under the tree and this is mathematically represented as

         [tex]P(A \ n\  U )   = \frac{Z}{ T}  [/tex]

Here Z is the total number of death under the tree after 2000 and it is mathematically represented as

         [tex]Z =  35 +  42[/tex]

=>       [tex]Z =  77 [/tex]

=>       [tex]P(A \ n\  U )   = \frac{77}{ 623}  [/tex]

=>      

Also

     [tex]P(A)[/tex] is the probability of the death occurring after 2000  and this is mathematically represented as

        [tex]P(A) =  \frac{T_b  +  T_c}{ T}[/tex]

=>      [tex]P(A) =  \frac{ 206+  182}{623}[/tex]

=>  

So

         [tex]P(U |D ) = \frac{\frac{77}{ 623} }{ \frac{ 206+  182}{623}}[/tex]

=>      [tex]P(U |D ) = 0.198 [/tex]

Generally the probability that the death was from camping or being outside and was before 2001 is mathematically represented as

      [tex]P(O | B) = \frac{T_z}{ T}[/tex]

Here [tex]T_z[/tex] is the total number of death outside / camping before 2001  and the value is  117  

So

            [tex]P(O \ n \ B) = \frac{117}{623}[/tex]

=>          [tex]P(O\ n \ B) = 0.188[/tex]

Generally the probability that the death was from camping or being outside given that it was before 2001 is mathematically represented as

       [tex]P(O | B) =  \frac{ P( O \ n \ B)}{ P(B)}[/tex]

Here [tex]P(B)[/tex] is the probability that it was before 2001 , this is mathematically represented as  

          [tex]P(B ) =  \frac{T_a}{T}[/tex]

=>       [tex]P(B ) =  \frac{235}{623}[/tex]

So

          [tex]P(O | B) =  \frac{ \frac{117}{623}}{ \frac{235}{623}}[/tex]

=>       [tex]P(O | B) =   0.498 [/tex]

-2 l - (-2) + y =6 => y = 6 - 2=> y = 4

-1 l - (-1) + y =6 => y = 6 - 1=> y = 5

0 l - (0) + y =6 => y = 6 + 0=> y = 6

1 l - (1) + y =6 => y = 6 +1 => y = 7

2 l - (2) + y =6 => y = 6 + 2=> y = 8

Answer:

x= 12

Step-by-step explanation:

(9x -4)° +(5x +16)° = 180° (int. ∠s, L//m)

9x -4 +5x +16= 180

14x +12= 180 (simplify)

14x= 180 -12 (-12 on both sides)

14x= 168

x= 168 ÷14 (÷14 on both sides)

x= 12

Answer:

The probability that, in any hour, less than 2 customers will arrive is 0.0067.

Step-by-step explanation:

The random variable X can be defined as the number of customers arriving hourly at the drive-through window at the Fidelity Credit Union.

The random variable X describes a finite number of occurrences of an event in a fixed time interval.

The random variable X follows a Poisson distribution with parameter λ = 7.1.

The probability mass function of X is:

[tex]P(X=x)=\frac{e^{-7.1}(7.1)^{x}}{x!};x=0,1,2,3...[/tex]

Compute the probability of less than 2 customers arriving as follows:

[tex]P(X<2)=P(X=0)+P(X=1)[/tex]

                [tex]=\frac{e^{-7.1}(7.1)^{0}}{0!}+\frac{e^{-7.1}(7.1)^{1}}{1!}\\\\=0.00083+0.00586\\\\=0.00669\\\\\approx 0.0067[/tex]

Thus, the probability that, in any hour, less than 2 customers will arrive is 0.0067.

Answer:

A)i) Population: Total number of people that reside in Florida..

II) Sample: 62348 people that took part in the random survey.

B) No, the estimates are not close to the truth of the entire population.

Step-by-step explanation:

A)i) The population is the total number of people that reside in Florida.

II) The sample is the 62348 people that took part in the random survey.

B) From the details given in the question, we will see that people who are not part of the healthcare system weren't included due to the fact that they used patients records to judge. This means that if they don't have healthcare, then they will have no patient records. Therefore, we can conclude that the estimates are not close to the truth of the entire population due to the fact that that those who weren't part of the Healthcare system were not considered.

[tex]\frac{3}{5} +\frac{1}{4} +\frac{3}{8} =[/tex] Distance Janie walked

First add [tex]\frac{1}{4} and\frac{3}{8}[/tex] canvert 1/4 by multiplying by 2/2 to get a commmon denominator.

[tex]\frac{1}{4} *\frac{2}{2} =\frac{2}{8}[/tex]

[tex]\frac{2}{8} +\frac{3}{8} =\frac{5}{8}[/tex]

Now find a common denominator for 3/5 and 5/8 by multiplying 3/5 by 8/8  and 5/8 by 5/5.

[tex]\frac{3}{5}*\frac{8}{8}=\frac{24}{40}[/tex]

[tex]\frac{5}{8}*\frac{5}{5}=\frac{25}{40}[/tex]

Now add them.

[tex]\frac{24}{40}+\frac{25}{40}=\frac{49}{40}=1\frac{9}{40}[/tex]miles

You can also convert all to decimals and add.

3/5 = .6

1/4 = .25

3/8 = .375

.6 + .25 + .375 = 1.225

Quantity of flour needed to make 20 pancakes =

[tex] = 1 \frac{2}{3} \: [/tex]

[tex] = \frac{3 \times 1 + 2}{3} [/tex]

[tex] = \frac{5}{3} \: cups \: of \: flour[/tex]

Then , number of pancakes that can be made from 1 cup of floor :-

[tex]20 \div \frac{5}{3} [/tex]

[tex]20 \times \frac{3}{5} [/tex]

[tex] \frac{60}{5} [/tex]

[tex] = 12 \: pancakes[/tex] .

Therefore , 12 pancakes can be made from 1 cup of floor .

Number of pancakes that can be made with 1 cup of flour = 12 pancakes

Number of pancakes that can be made with 9 cups of flour :-

= 9 × 12

= 108 pancakes

Therefore , I can make 108 pancakes with 9 cups of flour .

Yes , I have enough flour to make 100 pancakes . I say this because :-

With one cup of flour I can make = 12 pancakes

With 9 cups of flour I can make =

= 9 × 12

= 108 pancakes

As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .
