Answer:

Part B

This statement means that we are 95% confident that our confidence interval and our point estimate of our results from this sample contains the true proportion of national adults who fulfill a certain condition. The margin of error is plus or minus 4 percentage points in our survey, so we are fairly accurate / close to our point estimate.

Part C

Personally, I think that the minimum quota should be different, because nowadays very few people have landlines, and most people have cell phones. I would put it at 80% cell phones, 20% landlines, for the most representative survey possible.

Part D

Unfortunately, there isn't enough information to explain this one, because I can't see the link or view the responses and trends. I would give you the advice that you might want to include all variables and survey conditions: what type of survey was it? how many adults were sampled? what are your hypotheses or preconceived notions? what is the standard error? This should help; if not, please clarify.

Answer:

-12x^2 + 11xy - 2y^2

Step-by-step explanation:

Answer:

-12x² + 11xy - 2y²

Step-by-step explanation:

To solve this:

You can distribute -3x to 4x

-3x*4x = -12x²

Then distribute the -3x to -y

-3x*-y = 3xy

Distribute the 2y to 4x

2y*4x = 8xy

Distribute the 2y to -y

2y*-y = -2y²

-12x² + 3xy + 8xy - 2y²

Combine like terms and add 3xy to 8xy

Final Answer: -12x² + 3xy + 11xy - 2y²

Answer:

AE Measure: 23.36 units

Step-by-step explanation:

BA: 20cm

BC:20cm

BE:10cm  CE: 10cm

a^2 +b^2=c^2

BE^2 +BA^2 = AE^2

√100 + √400 = √500

AE^2 = √500 = 23.36

AE = 23.36 unit

Repeat effort :-)

Step-by-step explanation:

As ABCD is a square , BC = 20 cm

BE = 20/2 = 10 cm

Also , angle B = 90⁰

By pythagoras theorem :

AE² = 20² + 10²

AE² = 400 + 100

AE² = 500

AE = 10√5 cm

Step-by-step explanation:

Answer:

rolling a number less than 4=

1,2,3 are less than 4 and a die is 6 sided so that will be 3/6 which in lowest terms is 1/2

1/2 as a percentage is 1/2*100=50%

rolling an odd number=

on a 6 sided die there are 3 odd numbers which are 1,3 and 5=

3/6 which in lowest terms is also 1/2

so 1/2*100=50%

Answer: Reasonable

Step by Step:

You add week 1 and week 2

so, 11.9 + 15.05 = 26.95

That's basically it

The total distance travelled is 26.95, and the steps followed are given.

Sum is the output of the mathematical operation, Addition.

Jessica added the two distances in the table to get a sum of 26.95 miles.

The step followed to determine the sum of the distances is

Step 1:

Total distance travelled =  Distance travelled in Week 1 +  Distance travelled in Week 2

Step 2:

Total distance = 11.9 + 15.05

Total distance = 26.95 miles

Answer:

98

Step-by-step explanation:

Let b = the total number of boxes

b * 4/7 = 56

Multiply each side by 7/4

7/4 * b* 4/7 = 7/4 *56

b =98

The store had 98 boxes

Answer:

the second one, 98

Step-by-step explanation:

56/4=14

14*7=98

Step 1) Use the area formula to find the length of the radius

A = (3.14 x r^2) / 4

3.14 = (3.14 x r^2) / 4

12.56 = 3.14r^2

r^2 = 4

r = 2 feet

Step 2) Use the perimeter formula to find the perimeter

C = ((pi x 2r) / 4) + 2r

C = ((3.14 x 4) / 4) + 4

C = (12.56 / 4) + 4

C = 3.14 + 4

C = 7.14 feet

" Unit rate is defined as relation which is represented as the ratio of two different quantity in which value denominator is always one."

According to the question,

Given ratio of different quantity,

[tex]\frac{4}{6}:\frac{1}{3}[/tex]

Convert it into unit rate we get,

[tex]= \frac{4}{6}\times \frac{3}{1} \\\\= \frac{4\times 3}{6\times 1}\\ \\= \frac{12}{6} \\\\= 2 : 1[/tex]

Answer:

I think its 66

Step-by-step explanation:

Since if you draw it out properly F would be opposite of H.

Oppsite angles in a quadrilateral are supplementary(in a circle at least) meaning they add up to 180.

So 180-114= 66

So H=66

Answer:

The probability of a student to hit any small circle is 4.66 %.

Step-by-step explanation:

In order to determine the probability of the students to hit the small circles, we need to calculate the are of the rectangle and the area of each circle. These are shown below:

area circle = pi*r² = pi*(3)² = 28.26 in²

area rectangle = 35*52 = 1820 in²

Since there are three circles and the students can hit any of those the probablity of hitting them is given by the area of one circle multiplied by 3 and divided by the area of the rectangle.

p = [(3*area circle)/(area rectangle)]*100%

p = [(3*28.26)/1820]*100 = 4.66 %

Answer:

The mean  absolute deviation is 2

Answer:

M A D is 2

Step-by-step explanation:

A right triangular prism has 3 rectangular faces.

If each of the edges of the triangular base measures 4.5cm,

and the length (the height) of the prism is 22.5cm,

the 3 rectangular faces (sides of the box) are rectangles,

22.5cm long and 4.5cm wide.

Each face has a surface area of (22.5cm)(4.5cm)=101.25 square centimeters.

The total lateral surface area for the 3 rectangular sides of the box is

3(101.2 square centimeters)=303.75 square centimeters.

If the triangular faces of the box are triangles

with a base measuring 4.5cm and a height measuring 4.0cm,

the surface area of each triangular face is

(1/2)(4.5cm)(4.0cm)=9 square centimeters.

The surface area of the two triangular faces adds up to

2(9 square centimeters)=18 square centimeters.

The total surface area for the box is

303.75 square centimeters + 18 18 square centimeters= 321.75 18 square centimeters,

and that rounds up to highlight 322 square centimeters.

NOTE:

The answer above is the one your teacher wants,

but there is a problem with this problem.

An equilateral triangle with sides measuring 4.5cm

would have a height of approximately 3.9cm.

The Pythagorean theorem says so.

However, the 4.0cm value makes the calculations easier.

Answer:

A right triangular prism has 3 rectangular faces.

If each of the edges of the triangular base measures 4.5cm,

and the length (the height) of the prism is 22.5cm,

the 3 rectangular faces (sides of the box) are rectangles,

22.5cm long and 4.5cm wide.

Each face has a surface area of (22.5cm)(4.5cm)=101.25 square centimeters.

The total lateral surface area for the 3 rectangular sides of the box is

3(101.2 square centimeters)=303.75 square centimeters.

If the triangular faces of the box are triangles

with a base measuring 4.5cm and a height measuring 4.0cm,

the surface area of each triangular face is

(1/2)(4.5cm)(4.0cm)=9 square centimeters.

The surface area of the two triangular faces adds up to
