Answer:
1) Total length in inches = 162 inches
Step-by-step explanation:
express the total length of rope the three friends have in inches, feet, and yards.
2) Total length in Feet = 13.5 feet
3)Total length in yard = 4.5 yard
a) Total length in inches
Morgan has 42 inches of rope
Malcolm has 4 feet of rope
Convert to inches
1 foot = 12 inches
4 feet = 4 × 12 inches
= 48 inches
Roberto has 2 yards of rope
Convert to inches
1 yard = 36 inches
2 yards = 2 × 36 inches
= 72 inches
Hence, the total length of rope in inches
= (42 + 48 + 72)inches
= 162 inches
2) Total length in Feet
1 inch = 0.0833 feet
162 inches = 162 × 0.0833 feet
= 13.5 feet
2) Total length in yard
1 inch = 0.0278 yard
162 inches = 162 × 0.0278 yard
= 4.5 yard
Give me a picture of the problem and i will solve it
Answer:
a. Identify the population of interest in this study.
- 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)
