Answers

This question is incomplete, the complete question is;

A sociologist wants to construct an 80 confidence interval for the proportion of children aged 8-10 living in New York who own a cell phone.

(a) A survey by the National Consumers League taken in 2012 estimated the nationwide proportion to be 036. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.02?

Answer:

the required or needed sample size is 946

Step-by-step explanation:

Given the data in the question;

confidence level = 80%

⇒ 100( 1 - ∝ )% = 80%

100 - 100∝ = 80

100∝ = 100 - 80

∝ = 20/100

level of significance ∝ = 0.2

[tex]Z_{\alpha /2[/tex] = [tex]Z_{0.10[/tex] = 1.2816 { from z-table }

p = 0.36

Allowable margin of error E = 0.02

let n be the required sample size.

we know that

E = √( p( 1 - p) / n )

given that margin of error E = 0.02

⇒ √( p( 1 - p) / n ) × [tex]Z_{\alpha /2[/tex] = 0.02

⇒ √( 0.36( 1 - 0.36) / n ) × 1.2816  = 0.02

⇒ √( 0.2304 / n ) × 1.2816 = 0.02

√( 0.2304 / n ) = 0.02 / 1.2816

√( 0.2304 / n ) = 0.01560549

( 0.2304 / n ) = ( 0.01560549)²  

0.2304 / n  = 0.000243531318

n = 0.2304 / 0.000243531318

n = 946

Therefore, the required or needed sample size is 946

Which side of XYZ is the longest? A. WY B. XZ C. YZ D. Cannot be determined​

Answers

Answer:

B

Step-by-step explanation:

In a triangle the longest side is opposite the largest angle.

∠ Y = 180° - (60 + 43)° = 180° - 103° = 77°

∠ Y is the largest angle in the triangle, then the side opposite is the longest

That is XZ is the longest side → B

which are the expression represents the total area of the large rectangle?


no flile or link or i will be report you ​

Answers

Answer and Step-by-step explanation:

Expressions that represent the total area are:

6(m + n)

6n + 6m

(n + m)6

That is because to find the area of these rectangles, we multiply the length by the width. We would get 6m and 6n, which is one of those options.

Now, if we take out the 6 from each of the values, we get 6(m + n), or (n + m)6.

PLEASE ANSWER ASAP: Dianna can carry up to 15lbs in her backpack. Her lunch weighs 1 lb, her gym shoes weigh 2 lbs, and her books weigh 1.5 lbs each. Which inequality shows how many books Dianna can carry in her bag if she has her lunch and gym shoes?

Answers

Answer: A

Step-by-step explanation:

she can carry 1.5 pounds of books plus the extra 3 pounds as long as its less than or equal to 15 lbs

The inequality that shows the number of books that Diana can carry in her bag if she has her lunch and gym shoes is 3 + 1.5x  ≤ 15.

What inequality represents the number of books that Diana can carry?

The first step is to determine the total weight of the items in her bag:

1 + 2 = 3lbs

The second step is to determine the inequality sign to use:

the inequality sign to be used is the less than or equal to sign - ≤

The equation becomes: weight of items in her bag + (weight of one book x total number of books) ≤ weight the bag can carry

3 + 1.5x  ≤ 15

What is a straight line?

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Here, we have to points (2,4) and, (2,-7)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>(y-4)/(x-2)=(-7-4)/(2-2)

=>0 = x-2

=>x =2

Hence, the required equation is,  x =2

If Mr. Kim need to 5/8 yard of wire for a project he has a stick that is 1/8 yard long how many 1/8 in your lungs links does he need to measure to get 5/8 of a yard long

Answers

Answer:

5 stick lengths

Step-by-step explanation:

The question is not structured well. However, the following can be deduced

[tex]Wire = \frac{5}{8}yd[/tex]

[tex]Stick = \frac{1}{8}yd[/tex]

Required

How many of the stick length can be gotten from the wire length

To do this, we simply divide the length of the wire by the length of the stick.

So, we have:

[tex]Number = \frac{Wire}{Stick}[/tex]

[tex]Number = \frac{5/8yd}{1/8yd}[/tex]

[tex]Number = \frac{5/8}{1/8}[/tex]

Using a calculator, we have:
