use the accompanying statcrunch session to obtain a simple random sample of 5 high schools in the city of chicago.

Answers

Answer 1

Using sampling concepts, one sample of 5 high schools in the city of Chicago is given by:

Englewood Stem, Hyde Park, Lake View, Marshall, Noble - UIC.

What is the missing information?

The problem is incomplete, but researching it on a search engine, it gives us a list of 15 high schools in Chicago, and asks us to take a sample of 5.

What is population and sample?

Population: Collection or set of individuals or objects or events whose properties will be studied.Sample: The sample is a subset of the population, and a well chosen sample, that is, a representative sample will contain most of the information about the population parameter. A representative sample means that all groups of the population are inserted into the sample.

Hence, from the concepts of sample and populations, the sample of 5 means that we have to select 5 schools from the 15 listed, hence they are:

Englewood Stem, Hyde Park, Lake View, Marshall, Noble - UIC.

Answer:

The two circles intersect at one and only point A(0 , 0)

Step-by-step explanation:

Let ς₁ be the circle of equation :

ς₁ : (x - 2)² + y² = 4

and ς₂ be the circle of equation :

ς₂ : (x + 2)² + y² = 4 

Consider the point M (x , y) ∈ ς₁∩ς₂

M  ∈ ς₁ ⇔ (x - 2)² + y² = 4

M  ∈ ς₂ ⇔ (x + 2)² + y² = 4

M (x , y) ∈ ς₁∩ς₂ ⇒ (x - 2)² + y² = (x + 2)² + y²

⇒ (x - 2)² = (x + 2)²

⇒ x² - 4x + 4 = x²+ 4x + 4

⇒  - 4x = 4x

⇒  8x = 0

⇒  x = 0

Substitute x by 0 in the first equation:

(0 - 2)² + y² = 4

⇔ 4 + y² = 4

⇔ y² = 0

⇔ y = 0

Conclusion:

The two circles intersect at one and only point A(0 , 0).

a baker is building a rectangular solid box from cardboard to be able to safely deliver a birthday cake. the baker wants the volume of the delivery box to be 540 cubic inches. if the width of the delivery box is 3 inches longer than the length and the height is 4 inches longer than the length, what must the length of the delivery box be?

Answers

The length of the rectangular solid delivery box is 6 inches.

Volume of a rectangular solid, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units

It is given that, the volume of the delivery box is 540 cubic inches, the width of the delivery box is 3 inches longer than the length and the height is 4 inch longer than the length.

Width of the rectangular solid delivery box = (length + 3) inches

Height of the rectangular solid delivery box = (length + 4) inches

Now,

let us assume that the length of the rectangular solid delivery box is X.

So, Width = (X+3) inches and Height = (X+4) inches.

Volume of rectangular solid delivery box = Length × Width × Height

=> Length × Width × Height = 540 cubic inches.

After putting all the values in the above equation,

=> X × (X+3) × (X+4) = 540

=> X=6 inches

Therefore, the length of the rectangular solid delivery box is 6 inches.

$5 - $5 = $0 (another 5 $1 bills)

Total: 8 x $1 and 6 x $5

Answer:

The number of $5 bills is 6

The number of $1 bills is 8

Step-by-step explanation:

Given the number of $1 bills is x, and of $5 bills is y

Then x + y = 14 or x = 14 - y

And 1(x) + 5(y) = 38

then 1(14 - y) + 5y = 38

14 - y + 5y = 38

4y = 38 - 14

4y =24

y = 6

if the number of $5 bills is 6

then the number of $1 bills is 14 - 6 = 8

Chang wants to plant grass in his backyard. His backyard is in the shape of a rectangle. Its length is 32 feet and its width is 21 feet. Suppose each pack of seed covers 12 square feet. How many packs of seed will he need to cover the backyard?

Answers

Answer:

56 packs of seeds

Step-by-step explanation:

To find the area of Chang's backyard, we can use the formula for an area of a rectangle.

Area = length·width or A = lw

32·21 = 672 sq ft.

To find how many packets of seed he will need to cover the backyard, we can take the area of Chang's yard and divide it by how many square feet each pack of seed covers.

672/12 =  56

Chang will need 56 packs of seeds to cover the backyard.

Answers

The values of the functions are h(0) = 1, h(10) = 3, h(-3) = 7 and h(3) = 4

How to evaluate each of the function values from the piecewise function?

The piecewise function is given as:

h(x) = {7, when x<0

         {x+1, when 0 ≤x ≤4

          {√x-1, when x>4

Next, we solve the function values

1. Function h(0)

This means that x = 0

To do this, we make use of h(x) = x + 1 because x= 0 is in its domain

So, we have

h(0) = 0 + 1

h(0) = 1

2. Function h(10)

This means that x = 10

To do this, we make use of h(x) = √x - 1 because x= 10 is in its domain

So, we have

h(10) = √10 - 1

h(10) = √9

h(10) = 3

3. Function h(-3)

This means that x = -3

To do this, we make use of h(x) = 7 because x= -3 is in its domain

So, we have

h(-3) = 7

4. Function h(3)

This means that x = 3

To do this, we make use of h(x) = x + 1 because x= 3 is in its domain

So, we have

h(3) = 3 + 1

h(3) = 4

Hence, the values of the functions are h(0) = 1, h(10) = 3, h(-3) = 7 and h(3) = 4

Step-by-step explanation:

corporation uses trucks to transport bottles from the warehouse to different retail outlets. gasoline costs are per mile driven. insurance costs are per year. calculate the total costs and the cost per mile for gasoline and insurance if the truck is driven​ (a) miles per year or​ (b) miles per year. ​(round the cost per mile to the nearest​ cent, $x.xx.)

Answers

The total cost = $5000 (Option A) and $9400 (Option B)

Cost per mile = $0.33 (option A) and $0.25 (Option  B)

What is unitary method?

A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.

Given:

Cost of gasoline for each mile driven = $0.20Cost of insurance for each year = $2000

To find: Total costs and cost per mile, when the truck is driven (A) 15000 miles per year (B) 37000 miles per year.

Finding:

(A) By unitary method,

When the truck is driven 1 mile, cost of gasoline = $0.20

When the truck is driven 15000 miles, cost of gasoline = $ 0.20(15000) = $3000 in an year

Cost of insurance in an year = $2000

Thus, total cost = $ 3000 + $2000 = $5000

Now, for per mile cost:

Cost of gasoline = $0.20

Cost of insurance = $0.13

Thus, Cost per mile = $0.20 + $0.13 = $0.33

(B) Again, by unitary method,

When the truck is driven 1 mile, cost of gasoline = $0.20

When the truck is driven 37000 miles, cost of gasoline = $ 0.20(37000) = $7400 in an year

Cost of insurance in an year = $2000

Thus, total cost = $ 7400 + $2000 = $9400

Now, for per mile cost:

Cost of gasoline = $0.20

Cost of insurance = $0.5

Thus, Cost per mile = $0.20 + $0.5 = $0.25

Part of the proceeds from a garage sale was $330 worth of $5 and 520 bills. If there were 6 more $5 bills than $20 bills, find the number of each denomination.

Answers

The number of bills worth $20 is found to be 18 and the  number of bills worth $5 is 12.

What is defined as the linear equation in two variables?

A linear equation in two variables is one that is written in the form;

ax + by + c=0, where a, b, and c are real numbers and also the coefficients of x and y, i.e. a and b, are not equal to zero.

Now, as per the given question;

Let 'X' be the number of bills worth $20.

Let 'Y' be the number of bills worth $5.

Then, the total cost of the bills $330 is written as;

330 = 20X + 5Y

Now, if 6 more $5 bills is added to than $20 bills.

Y = X + 6, as there are 6 more $5 bills than $20 bills.

Substitute the value of Y in original equation.

330 = 20X + 5(X+6)

330 = 20X + 5X + 30

Further solving the equation.

300 = 25X

X = 300/25

X = 12 (number of bills worth $20)

Substitute the value in Y to find the number of bills worth $5.

Since, there are 6 more $5 bills than $20 bills, Y = 12+6 = 18

Thus, there are 18 number of bills worth $20.

Answers

Answers:

   16.50     for the first box

    10         for the second box

======================================

Explanation:

Part (a)

Plug in x = 20 and solve for p.

0.2x+4p = 70

0.2*20+4p = 70

4 + 4p = 70

4p = 70-4

4p = 66

p = 66/4

p = 16.50

They should charge $16.50 per gallon if the demand is 20 million gallons.

------------------------

Part (b)

Let's say the price is initially $10 per gallon. The starting price could be anything you want.

Plug p = 10 into the equation and solve for x.

0.2x+4p = 70

0.2x+4*10 = 70

0.2x + 40 = 70

0.2x = 70-40

0.2x = 30

x = 30/(0.2)

x = 150

The demand is 150 million gallons if the price were $10 per gallon.

Now let's increase the price by $0.50 to get to p = 10.50

Let's solve for x based on this larger value of p.

0.2x+4p = 70

0.2x+4*10.50 = 70

0.2x+42 = 70

0.2x = 70-42

0.2x = 28

x = 28/(0.2)

x = 140

The demand is now 140 million gallons if the price were $10.50 per gallon.
