9.The Bridgeport water department has a monthly service charge of $12.60 and a volume charge of
$1.38 for every 100 cubic feet of water. Write an equation that can be used to determine the Morgan
family's monthly water bill.

Answers

[tex]y = 1.38x + 12.60[/tex]

Step-by-step explanation:

the 12.60 is going to be charged every months no matter what it's fixed so that's why it's added! the 1.38 is a rate, so how many cubic inches she uses in increments of 100 she will be charged so that depends on how much she uses in addition to that 12.60for example she uses 700 cubic feet of water once month well (x) will be 7 because u divide it by 100 and it'll give u ur "x". put it into the formula and it'll give the price she'll have to pay. 1.38(7) + 12.60 and this will equal $21.70 !

If g(x) =5-9x and f(x) = 5+ 3x
Find g(2)
Find f(g(2))

Answers

Answer:

Step-by-step explanation:

g(2)= 5-9(2)

= -13

f(g(2))= 5+3(-13)

= -34

Answer:

g(2) = -13

f(g(2)) = -34

Explanation:

For g(2), just substitute 2 in for the x, multiply, and simplify.

g(x) = 5-9(x)

g(2) = 5-9(2) = 5-18 = -13

For f(g(2)), substitute this output in for x, multiply, and simplify.

f(x) = 5 + 3(x)

f(g(2)) = 5 + 3(g(2)) = 5 + 3(-13) = 5-39 = -34

In the cafeteria, 100 milk cartons were put out for breakfast. After breakfast there were 40 milk cartons left. What is the ratio of milk cartons taken to total milk cartons put out for breakfast.

Answers

Answer:

3:5

Step-by-step explanation:

There were 100 milk cartons there and someone took 100-x=40.  Add 100 on both sides 40-100=-60 so 60 milk cartons were taken.  So the ratio would be 60:100, which can be simplified further 30:50 15:25 3:5.

WXYZ is a kite. Angle WXY has a measure of 133 degrees and angle ZWX has a measure of 60 degrees. Find the measure of angle ZYW.

Answers

Answer:

ZYW = 17.

Step-by-step explanation:

ZYW = XYW = 180 - 133 + 30(sum of angles in a triangle) = 17.

The measure of angle ZYW is 17.

Given that,

The Angle WXY has a measure of 133 degrees.And, the angle ZWX has a measure of 60 degrees.

Based on the above information, the calculation is as follows:

= 180 - 133 - 30

= 17

Also ZYW = XYW

Therefore we can conclude that the measure of angle ZYW is 17.

To multiply mixed numbers:

Step-by-step explanation:

1. convert to improper fractions

2. top * top

3. bottom * bottom

4. convert back into a mixed number

Answer:

Hi!

In these questions you're being asked to multiply mixed numbers. The easiest way to do this is to convert the mixed numbers to improper fractions, and then multiply them in that form.

For the first question:

[tex]1\frac{3}{5} = \frac{8}{5} ; 1\frac{2}{5} =\frac{7}{5} \\[/tex]  To convert the mixed numbers to improper fractions, you just     multiply the denominator by the whole number, and then add it to the current  numerator, forming the new numerator. The denominator stays the same.

[tex]\frac{8}{5} *\frac{7}{5} = \frac{56}{25}[/tex]       Next, multiply together the numerators, and then multiply together the denominators.

[tex]\frac{56}{25} = 2\frac{6}{25}[/tex]

Luke and Leia are selling hot dogs and hamburgers at a minor league baseball game. At the end of the day they determine they have sold a total of 45 items and earned $195. If hot dogs cost $4 and hamburgers cost $5, how many did they sell of each?

What would be a system of equations for the scenario above?

Answers

Answer:

15 hamburgers were sold and 30 hotdogs were sold.

The systems of equations are x + y = 45 and 4x + 5y = 195.

Step-by-step explanation:

Let's make two equations.

x + y = 45

This represents the total of hotdogs and hamburgers sold

4x + 5y = 195

This represents the amount of money made for each food.

These are systems of equations, when you use 2 equations to solve a problem. I will use the strategy, Elimination for the following systems of equations. Anyways the goal is to multiply a number to x + y = 45 to cancel out one of the variables in 4x + 5y = 195. In other words, when we add these equations, the sum of the xs or ys will equal 0.

Let's multiply -5 to both x and y.

Now we have -5x -5y = -225 + 4x + 5y= 195

We will end up with -x = -30. This means that x = 30.

Now that we know x = 30, we can plug in 30 as x in one of the equations. I will plug in 30 into x + y = 45. 30 + y = 45.

Solve for y in 30 + y = 45, so y=15.

This means 15 hamburgers were sold and 30 hotdogs were sold.

A resident of Bayport claims to the City Council that the proportion of Westside residents

(2) The City Council decides to test this claim by collecting a random sample of resident incomes from the Westside of town and a random sample of resident incomes from the Eastside of town.

Calculate the value of the test statistic (round to 4 decimal places).
Calculate the p-value (round to 4 decimal places).

Answers

Answer:

The test statistics is  [tex]z =  -1.56 [/tex]  

The p-value is   [tex]p-value =  0.05938 [/tex]

Step-by-step explanation:

From the question we are told  

   The West side sample  size is [tex]n_1  =  578[/tex]

    The  number of residents on the West side with income below poverty level is [tex]k  = 76[/tex]

    The East side sample size  [tex]n_2=688[/tex]

  The  number of residents on the East side with income below poverty level is [tex]u  = 112[/tex]

   The null hypothesis is  [tex]H_o  :  p_1 = p_2[/tex]

    The alternative hypothesis is  [tex]H_a :  p_1 <  p_2[/tex]

Generally the sample proportion of  West side is  

     [tex]\^{p} _1 = \frac{k}{n_1}[/tex]

=>   [tex]\^{p} _1 = \frac{76}{578}[/tex]

=>   [tex]\^{p} _1 =  0.1315 [/tex]

Generally the sample proportion of  West side is  

     [tex]\^{p} _2 = \frac{u}{n_2}[/tex]

=>   [tex]\^{p} _2 = \frac{112}{688}[/tex]

=>   [tex]\^{p} _2 =  0.1628 [/tex]

 Generally the pooled sample proportion is mathematically represented as

    [tex]p = \frac{k + u}{ n_1 + n_2 }[/tex]

=>  [tex]p = \frac{76 + 112}{ 578 + 688 }[/tex]

=>  [tex]p =0.1485[/tex]

Generally the test statistics is mathematically represented as

[tex]z = \frac{\^ {p}_1 - \^{p}_2}{\sqrt{p(1- p) [\frac{1}{n_1 } + \frac{1}{n_2}  ]}  }[/tex]

=> [tex]z = \frac{ 0.1315  - 0.1628 }{\sqrt{0.1485(1-0.1485) [\frac{1}{578} + \frac{1}{688}  ]}  }[/tex]  

=> [tex]z =  -1.56 [/tex]  

Generally the p-value  is mathematically represented as

          [tex]p-value =  P(z <  -1.56 )[/tex]

From z-table  

         [tex]P(z <  -1.56 ) =  0.05938[/tex]

So

     [tex]p-value =  0.05938 [/tex]

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 145145 millimeters, and a standard deviation of 77 millimeters. If a random sample of 3131 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by greater than 33 millimeters

Answers

Answer:

The probability that the sample mean would differ from the population mean by greater than 33 millimeters is 0.0174

Step-by-step explanation:

[tex]Mean = \mu = 145 mm[/tex]

Standard deviation =[tex]\sigma = 7[/tex]

We are supposed to find the probability that the sample mean would differ from the population mean by greater than 3 millimeters

[tex]P(|x-\mu|>33)=1-P(|x-\mu|<3)\\P(|x-\mu|>33)=1-P(-3<|x-\mu|<3)\\P(|x-\mu|>33)=1-P(\frac{-3}{\frac{\sigma}{\sqrt{n}}}<\frac{|x-\mu|}{\frac{\sigma}{\sqrt{n}}}<\frac{-3}{\frac{\sigma}{\sqrt{n}}})\\P(|x-\mu|>33)=1-P(\frac{-3}{\frac{7}{\sqrt{31}}}<\frac{|x-\mu|}{\frac{\sigma}{\sqrt{n}}}<\frac{-3}{\frac{7}{\sqrt{31}}})\\P(|x-\mu|>33) =1-P(-2.38<z<2.38)\\P(|x-\mu|>33) =1-(P(z<2.38)-P(z<-2.38))\\[/tex]

Using Z table

                   = 1-(0.9913-0.0087)

                  =0.0174

Hence  the probability that the sample mean would differ from the population mean by greater than 33 millimeters is 0.0174

Suppose there is a 27.4% probability that a randomly selected person aged 40 years or older is a jogger. In addition, there is a 29.3% probability that a randomly selected person age 40 years or older is male, given that he or she jogs.

Required:

b. Would it be unusual to randomly select a person aged 40 years or older who is male and jogs?

Answers

Answer:

a

    [tex]P(M  \  n \  J ) = 0.0802 [/tex]

b

  Yes

Step-by-step explanation:

From the question we are told that

    The  probability that a random  selected person of age 40  years or older  is a jogger is [tex]P(J) =  0.274[/tex]

    The  probability that a random  selected person of age 40  years or older  is a male given that he/she jogs  is  [tex]P(M |J) = 0.293[/tex]

Generally the probability that a randomly selected person age 40 years or older is male and jogs

    [tex]P(M  \  n \  J ) = P(M|J) *  P(J)[/tex]

    [tex]P(M  \  n \  J ) = 0.293 * 0.274 [/tex]

     [tex]P(M  \  n \  J ) = 0.0802 [/tex]

Generally it would  be unusual  because the probability that a randomly selected person age 40 years or older is male and jogs is  greater than 0.05[border line for statistical  significance]
