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:

Step-by-step explanation:

If we take the arcs to mean that those angles are congruent, then the sum of exterior angles is ...

  x° +2y° +75° +67° = 360°

  y = 109 -x/2 . . . . . . subtract non-x terms and divide by 2

Because x° forms a linear pair with a right angle, we know ...

  x° = 180° -90° = 90°

Then ...

  y = 109 -90/2 = 64

The values of x and y are 90 and 64, respectively.

Answer:

0.25 = 25% probability of choosing white shoes and a green shirt

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

The probability of choosing a shoe is independent of the shirt. So we find each separate probability, and then multiply them.

Probability of choosing white shoes:

2 shoes option, one of which is white. So

[tex]P(A) = \frac{1}{2}[/tex]

Probability of choosing a green shirt:

2 shirts options, one of which is green. So

[tex]P(B) = \frac{1}{2}[/tex]

What is the probability of choosing white shoes and a green shirt?

[tex]P(A \cap B) = P(A)*P(B) = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4}[/tex]

0.25 = 25% probability of choosing white shoes and a green shirt

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

I rotate 270 degrees means to turn 90 degrees clockwise 3 times, If You rotate once it is in the +x, -y rotate again -x, -y, and the last time is -x +y. Please give brainliest if this is helpful. Sorry if this is confusing :)

The other person did a 180 degrees rotation instead of 270

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

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

Hence, the graph of function g is graph Z
