  • all the population of the country

b. Identify the sample for the study.

  • 50 adults (the ones that were surveyed)

c. Identify the parameter of interest in the study.

  • the parameter of interest is the people that believe that coffee shops are overpriced

d. Find and interpret a 95​% confidence interval for the parameter of interest.

z score for a 95% confidence level = 1.96

margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579

95% confidence level interval:

0.4 - 0.13579 = 0.26421

0.4 + 0.13579 = 0.53579

  • 95% confidence interval (0.26421 , 0.53579)

Given teo circles whose radii are 9" and 24", the ratio of thuer circumfrence is?
saul85 [17]

Answer:

The ratio is 3:8

Step-by-step explanation:

The circumference of a circle can be calculated using the formula;

C = 2 * pi * r

for 9 inches;

C = 2 * pi * 9 = 18 pi inches

For 24 inches;

C = 2 * pi * 24 = 24 pi inches

The ratio is thus;

18 pi : 48 pi

divide through by 6 pi

= 3: 8

2(2y − 12) = 0 PLS SHOW YOUR WORK<br><br> 20 points
g100num [7]

Answer:

y = 6

Step-by-step explanation:

2(2y -12) = 0

a. Distribute the problem out

4y - 24 = 0

b. Add 24 to both sides to seperate the constants and the terms.

4y - 24 = 0

    +24    +24

4y = 24

c. Divide 4 out of both sides to isolate y

y = 6

d. Plug the 6 back into the equation to see if the answer is correct.

2(2(6) -12) = 0

2(12-12) = 0

2(0) = 0

Hope this helps!
