 0.0432

Step-by-step explanation:

Formula of Margin of Error :-

Given : Sample size : n= 400

The proportion of individuals use public transportation.=

Level of confidence = 0.95

Significance level :

Critical value :

Substitute the values in the given formula , we get

Hence, the margin of error for the confidence interval for the population proportion with a 95% confidence level. = 0.0432

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
