Over the course of a week, an environmental activist randomly stopped 1,200 people on the street and asked whether they were willing to pay higher prices for gas in order to protect the environment. out of the 1,200 people, 708 of them said they were willing to pay higher prices for gas. with a 99% confidence level (z*-score = 2.58), the activist wants to determine a confidence interval for the estimated proportion of people willing to pay higher prices for gas in order to protect the environment.

d. between 55.3% and 62.7%

Step-by-step explanation:

edgu 2020

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
