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:

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:

Quantitative Discrete

Step-by-step explanation:

The data about the average salary of all general motor workers cooled ONLY as WHOLE U. S DOLLARS

Firstly, data involving worker's salary are best expressed in figure, hence making such data numerical in nature. Numerical variables are quantitative data as it allows for numerical computation and analysis such as addition, subtraction, mean of the data values and so on.

Secondly, since these data has been strictly restricted to be expressed in whole numbers, this makes the range of the data collected finite and hence countable. This properties ensure that the quantitative data (average salary) is discrete in nature.

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:

Step-by-step explanation:

x2 - 4x - 12 = 0

x2 - 6x + 2x - 12= 0

x(x - 6) + 2(x - 6) = 0

x + 2 = 0

x = - 2

x - 6 = 0

x = 6

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]

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

Therefore,

[tex](\frac{25x^{2} }{2x+6})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex](\frac{25x^{2} }{2(x+3)})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{5x}{(x+3)}[/tex]

Explanation:

2 x 4 = 8

8 x 2 = 16

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:

Step-by-step explanation:

[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

Also 1 [tex]\frac{9}{40}[/tex] = 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 .

Answer:

Answer:

X l Y

-2 l 4

-1 l 5

0 l 6

1 l 7

2 l 8

Step-by-step explanation:

X l Y

-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

Note: - (-a) + b = a + b

- (a) + b = - a + b
