Answer:
We have 96% of confidence that the true proportion of people who responded that they have a plan to buy one electric car is between (0.121 and 0.303).
Step-by-step explanation:
For this case the estimated proportion of people who responded that they have a plan to buy one electric car is given by:
Where X represent the number of people who responded that they have a plan to buy one and n represent the sample size selected
We know that the confidence level for this case is 96% of confidence, then our significance level would be 
and 
. And the critical value would be:
The confidence interval for the true proportion is given by this expression:
Replacing the data given we got:
We have 96% of confidence that the true proportion of people who responded that they have a plan to buy one electric car is between (0.121 and 0.303).

Step-by-step explanation:
Answer: 152.46 squared centimeters.
Step-by-step explanation:
- The equation to find the area of the trapezoid is A = ½ (6.6 + 16.5) 13.2
- Distribute ½ into (6.6 + 16.5) . A = (3.3 + 8.25) 13.2.
- Add the numbers inside the parenthesis. A = 11.55 * 13.2
- Multiply 11.55 * 13.2. A = 152.46.
The correct answer is A. "separate but equal"
Explanation:
The excerpt presented belongs to the decision taken by Chief Justice Earl Warren (chief judge from 1943- 19539) as part of Brown v. Board of Education. In this, Chief Justice Warren declares integration is a must and the doctrine of "separate but equal" is unconstitutional as he demands "to admit to public schools on a racially nondiscriminatory basis".
Moreover, the doctrine of "separate but equal" defined by the Chief Justice as "inherently unequal" was a strategy and phrase opponents of integration used to avoid the process of integration as this implied building separated facilities for non-whites and claiming these facilities offered the same conditions. However, this doctrine still promoted discrimination as non-whites were not admitted or accepted in white schools. Moreover, in most cases the education offered and conditions were unequal. According to this, the phrase or doctrine used to drag out the process of desegregation or slow down integration is "separate but equal"
