Answer: If in a prior study, a sample of 200 people showed that 40 traveled overseas last year, then n= 385

If no estimate of the sample proportion is available , then n= 601

Step-by-step explanation:

Let p be the prior population proportion of people who traveled overseas last year.

If p is known, then required sample size = [tex]n=p(1-p)(\dfrac{z^*}{E})^2[/tex]

z-value for 95% confidence = 1.96

E = 0.04  (given)

[tex]p=\dfrac{40}{200}=0.2[/tex]

[tex]n=0.2(1-0.2)(\dfrac{1.96}{0.04})^2=384.16\approx385[/tex]

Required sample size = 385

If p is unknown, then required sample size = [tex]n=0.25(\dfrac{z^*}{E})^2[/tex]

, where E = Margin of error , z* =critical z-value.

z-value for 95% confidence = 1.96

E = 0.04  (given)

So, [tex]n=0.25(\dfrac{1.96}{0.04})^2=600.25\approx601[/tex]

Required  sample size = 601.

Answer:

a) Interquartile range= upper quartile- lowwr quartile

= Q3- Q1

= 4.75-2.25

= 2.50

b) ( 2.5 ÷ 6 ) × 100

Answer:

1105.28

Step-by-step explanation:

d = 16

r = d/2 = 8

Formula:

SA = 2πr² + 2πrh

SA = 2(3.14)(8²) + 2(3.14)(8)(14)

SA = 2(3.14)(64) + 2(3.14)(8)(14)

SA = 401.92 + 703.36

SA = 1105.28

Answer: 20-10

Step-by-step explanation: 486-466 is 20. Half of 20 is 10. Any expression that equals ten is 1/2 as large as 486-466.

The expression is 1/2 as large as 486-466 is with the data 10.

Fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Let us understand this concept using an example. The following figure shows a pizza that is divided into 8 equal parts. Now, if we want to express one selected part of the pizza, we can express it as 1/8 which shows that out of 8 equal parts, we are referring to 1 part.

Given:

Class = 486 - 466

We have given a class whose upper limit = 486

and, lower limit = 466

the range or difference between class

=486 - 466

=20

Thus, the 1/2 of range is 10.

Hence, expression is 1/2 as large as 486-466 is with the data 10.

The graph of function g is graph Z because the graph of function g is the result of a horizontal compression applied to the graph of function f

Function f(x) is given as:

[tex]f(x) = (\frac 12)^x[/tex]

Function g(x) is given as:

g(x) = f(kx)

The above represents a horizontal compression of function f(x) to form function g(x)

The graph that represents a horizontal compression is graph Z

Answer:

A

Step-by-step explanation:

1) multiply 2 for 5w and 15

5w -13 + 2w + 6 + 10w + 30 = P

2) sum the therms with w and the term without it

17w + 23= P

3) add -23 at the two terms

17w + 23 - 23= P - 23

17w = P - 23

4) divide the two terms by 17

w = (P-23)/17
